(TPAG). This small

cemetery is approximately

8 km south-east of the

Hardwicke Bay along

Cutline Road, on Yorke

Peninsula. As weed invasion is a serious threat to the

nationally endangered Arachnorchis intuta or ghost

orchid which is located at this site, this is a necessary

task. Anyone is invited to join this weeding project but

as the Friends of Brentwood Cemetery will be

providing lunch it is requested that anyone intending to

participate needs to notify NRM Team Leader,

Changes to Field Trip Procedures

From time to time field trips may need to be cancelled

for various reasons beyond our control. In such

circumstances folk intending to participate need to be

informed and to that end the committee has decided to

require bookings for field trips.

The preferred method is to book through:

[email protected] OR if that is not

convenient phone Rosalie at 8294 8014.

It also pays to check the NOSSA website to check the

status of any field trip. http://nossa.org.au/events/

NOTE: Following recent rains the field trip to Mt Billy

will now take place.

SUMMARY OF APRIL MEETING

Lorraine Badger

The guest speaker for the night was Jason Tyndall, regional coordinator of

Natural Resource Management (NRM) which is hosted by the City of

Onkaparinga. His chosen topic, “Orchid Stories: Connecting children to

nature through orchids” proved to be a fascinating and thought provoking

story.

Finding ways to connect children with nature is more important today than

at any other time in history and Jason shared his passion for working with

children in various schools. In his talk he sought to demonstrate the ways

in which he imparts his message by using the powerful form of

storytelling. Accompanied by a photographic power point he shared how

he had used orchids, which he has found to be one of the most interesting

plants, to engage children.

FROM THE PRESIDENT

Robert Lawrence

I am honoured to be able to write my first article as

President of the Native Orchid Society of South

Australia Incorporated.

I would like to thank Geoff Borg who stepped into the

role of President two years ago and oversaw a time of

adjustment. During his term Bill Dear moved to

Western Australia and Cathy Houston was no longer

available to serve the Society. The contribution made

by each of them is sorely missed.

I would also like to thank John Bartram who stepped in

to the role of Secretary early in 2013 after I found it

necessary to leave the role. This enabled the Society to

continue to function. I am pleased to welcome

Michael Clark as Minutes Secretary for the committee

meetings. Bob Gunn has kindly commenced taking

minutes of the general meetings, thus helping to share

the load.

In the later part of the year 2013 Helen Lawrence

started as Assistant Editor and produced an updated

format. John and Lorraine Badger commenced in the

role of Editor from the start of this year. David Hirst

has done a wonderful job as Editor for eleven years

and has served the Society well throughout this period.

He has given the new editorial team an example to

emulate.

Looking ahead, the Society faces a number of

challenges. The number of growers benching plants

and contributing to the annual Spring Show is

dwindling and there appears to be no new growers. It

has been exciting to learn about Trevor Gerrard in his

role as Education Officer of the Orchid Club of South

Australia with the Orchids in Schools Program. We

hope that this will contribute to a new generation of

orchid growers and that

some will take a particular

interest in Australian

orchids.

We also want to make sure

the range of activities and

publications meet the

expectation of all of our

members, many of whom

receive the Journal without

attending general meetings

or field trips. We hope we provide a range of materials

that readers find interesting.

New and exciting opportunities could be started in the

next couple of years. These include a web-based

interactive orchid identification key and

commencement of directed data collection for citizen

science projects on topics such as the distribution of

orchids and the timing of flowering.

This is just a brief snapshot of issues. In writing these

I am mindful of contributions of particular members

that I have not mentioned above; these continue to be

important and I certainly want those who contribute to

know that they are valued. Members are more than

welcome to bring to the attention of the Management

Committee any issues that should be addressed or

would make the Society more relevant to its members,

or if we are doing things well that should not be

changed.

NOSSA @ AUSTRALIAN PLANT SOCIETY AUTUMN SHOW

NOSSA members recently promoted the society at the APS Autumn Sale with a

display of native orchid material even though there were no orchids for sale on this

occasion. Time was taken on the previous to set up the area in such a manner as to

attract the show goers. Gordon Ninnes’ expertise combined with the assistance of

Jan Adams and Rosalie Lawrence meant that people were certainly drawn to the

area on the show days. A favourite attraction was the society’s orchid diorama

created with replica orchids cleverly formed from paper by former member Thelma

O’Neill. Thanks go to all who helped out over the two days.

WINNING PICTURE FOR APRIL 2014

ROSALIE LAWRENCE

With the range of photographs

submitted it is always difficult to guess

which picture is likely to be the winner

but somehow this month’s winning

photograph by Lorraine Badger was not

surprising. With a common name of

Queen Orchid, Thelymitra crinita is

aptly named for the flower has a quiet

regal air of elegance and delicacy that

would appeal to many people. Other

entries were: Jane Higg’s Eriochilus

(2nd), John Badger’s Corunastylis sp

Adelaide Hills (equal 3rd), Helen

Lawrence’s Jonesiopsis capillata

(equal 3rd), David Hirst’s Pterostylis

laxa, David Mangelsdorf’s Acianthus

pusillus, Pauline Meyers’ Caladenia

crebra and Marg Paech’s Calochilus

robertsonii,

T crinita is a common Western

Australian orchid that can be found

from Perth around to Albany with a

disjunct area near Esperance. Back in

1839, it was one of 60 orchids named

by John Lindley in ‘Appendix to the

first twenty-three volumes of Edwards’

Botanical Register together with A

Sketch of the Vegetation of the Swan

River Colony’. Though the register is

written in English the species

description is in Latin, reproduced here

for all those Latin buffs –

(214) helymitra [sic] crinita; folio

radicali oblongo apiculato glabro,

raceme cylindraceo, floribus purpureis,

cuculli laciniis lateralibus barbatis

unguiculatis intermediâ fornicatâ

emarginatâ dorso glanduloso-villosâ.

On a recent visit to the Herbarium, Michelle Waycott, Chief Botanist, explained that there is a strict botanical standard for describing a species. You may be pleased to know that at the 18th International Botanical Congress in Melbourne, Australia in July 2011, it was

determined that from the 1st January 2012 it was no

longer mandatory for descriptions to be in Latin only. English can now be used.

For anyone wishing to enter the monthly photographic

competition images can be:

1. emailed to [email protected] or

2. mailed to PO Box 565, Unley SA (5061) or

3. brought to the meeting on the night

ORCHIDOLOGOGIST JOHN LINDLEY (1799-1865)

R OSALIE LAW R ENC E

John Lindley (1799 - 1865), who named the above mentioned Thelymitra crinita, was one of the world’s earliest orchidologists and has been described as the Father of Modern Orchidology (Pridgeon, p.1). Having

no formal university education his career began under Sir Joseph Banks as assistant-librarian. He eventually rose to Professor of Botany, University College, London, amongst many other numerous official duties and public activities. It was the result of Lindley’s work and involvement with a group of other like-minded men that Kew Garden was saved from

destruction and Corn Tax was repealed at the time of the great Irish potato famine.

Although orchids were not his only area of interest

they were his passion and the common name ‘orchid’ was introduced by him in 1845. Lindley became involved with the naming of orchids at a time when the western world was discovering the wealth of the orchid world and his subsequent work on orchids was prodigious. He personally examined and named thousands of species specimens, with one author

stating that Lindley named over 6,000 orchid species, establishing over 120 genera. Notably he wrote three major orchid works Genera and Species of Orchidaceous Plants (1830-1840), Sertum orchidaceum (1838), and Folia orchidacea (1852-1855). He also wrote for the general public and one delightfully readable textbook was Ladies’ Botany or A

Familiar Introduction to the Study of the Natural System of Botany Volume I and II (1834 – 1837).

Though not referring specifically to South Australia, he lamented “that there are still, however, many species from the East and North Coast (of Australia), with which he has no acquaintance” [sic]. As far as I can

determine none of our endemic orchids were named by him.

REPORT ON NOSSA OUTING WE DID NOT HAVE

LEO DAVIS

Our quest for Leporella fimbriata at

Scott Conservation Park was pencilled

into my Planner so indelibly that I

headed off on my own searches, that

day and on others, and I report on

those forays.

I headed for Scott Creek C.P. first (no,

even though for some years I didn’t

realise Scott and Scott Creek were

NOT the same place, I do know now)

in my usual dream state, so missed the

Stirling turnoff, and settled on

Meadows Flat instead. The Midge

Orchid (Corunastylis sp.) plants John

Badger had led us to on the last visit

were well past flowering, now

pumping up their ovaries, and there

was not a sign of Parson’s Bands

(Eriochilus sp.)

On then to the always reliable Knott Hill NFR

where the results were the same, with the addition

of a single double flowered and a single triple

flowered specimen of the Fringed Hare Orchid (L.

fimbriata). You know what an odd bod I am and

how easily pleased, so you’ll not be surprised that

the day’s highlight was finding many leaves of the

Small Flying Duck, (Paracaleana minor), to 68 x

2 mm, and its large relative, Caleana major, to 42

x 5 mm. These very late flowering species are

always among the first out of the blocks.

I had high hopes for Scott Creek C.P. because Bob

Bates had shown us L. fimbriata growing in an

unexpected location, among Oyster Bay Pines

(Callitris rhomboidea) during our May 27, 2012

outing. More than 20 flowering plants were found

and many more in leaf only. Hopes were dashed

when I arrived on April 30, this year because a

fire, controlled or not, had gone through the area

recently. My plastic tags, on Thelymitra

benthamiana, T. carnea and Caladenia pusilla

sites, are now, let’s say, a lost cause. The Oyster

Bay Pines were gone. Down along the creek the

fire had either not taken or had been held at bay

and a few Parson’s Bands were in flower, Midge

Orchids were in fruit and Pterostylis pedunculata

were well in leaf.

Later the same day I went across to Mark Oliphant

CP and along the Waterfall Track found Parson’s

Bands in flower all along the track. Those few I’d

seen in flower back on March 24 were now in

fruit. There is a wide variation in prime flowering

time at the various locations.

There are clearly local populations of orchids.

Along about 300 or more metres of Waterfall

Track I saw hundreds of Parson’s Bands flowers,

in spasmodic and dense distributions, and I saw

just one double flowered spike. Along Moore’s

Road, at the top of Morialta C.P., throughout the

first half of April, I watched the Parson’s Bands

gradually come into flower and along a 200 m

stretch of fire track verges there were several areas

busy with plants and I found numerous double

flowers and in two spots found triples surrounded

by doubles. It’s all in the genes, I say.

2014 ORCHID SEASON

Robert Bates

After a very dry March and April in the Adelaide Hills

and most of coastal South Australia the wild orchids

were looking very sick due to water deficit and our

first ever autumn plague of flower thrips.

Our April field trip was cancelled and consideration

given to postponing the May excursion. Fortunately

heavy rain at the end of April turned the situation

around and orchid leaves began to show, right on time

indicating an above average orchid season.

Further north in the Gawler and Flinders, heavy rains

in February were of no benefit to orchids but good rain

in early April and early May set the scene for a bumper

orchid year on our desert fringes. Certainly autumn

orchids in the north have been impressive already,

especially in areas burnt by the Bangor Fire.

Editors’ Note: The year certainly has seen a slow start

to the orchid season. The following historic article

makes a good comparison with 2014 as well as

interesting reading.

FIELD TRIP TO HINDMARSH FALLS AND KNOTT HILL 25 4 1981

R.J. Markworth

Reprint from Native Orchard Society of South Australia Journal Vol. 5 No p.35-37

Adelaide's unusually long ‘Indian summer' provided a

really good turnout of members with a perfect autumn

day in which to enjoy our first field trip for 1981.

After some initial socializing involving a great deal of

chin-waging (an important aspect of the Society's

activities which excursions provide excellent

opportunities to indulge in), we walked from the

Hindmarsh Falls picnic area to view Pterostylis obtusa

in one of the few locations in South Australia where it

seems to grow.

The location accords remarkably well with Nicholls'

description of the plants ‘Eastern States' habitat, "…

most commonly or rocky timbered hill slopes - it may

be found plentifully among ferns and on mossy slopes

in sheltered forest areas”

In his delightful little book "South Australian Orchids"

(1911), Dr. R.S. Rogers made the following reference

to P. obtusa: "P. obtusa has quite a blunt tongue." …

obtusus (Latin) - blunt ..:... " This species is said to

have been found at Port Elliot. For many years 1

hunted it unsuccessfully, but two years ago I ran it to

earth in the Ravine de Casoars, in the unfrequented

west coast of Kangaroo Island. Since then I have

received specimens from Mount Muirhead "... between

Millicent and Mount Burr "collected by a school child

in the district."

In the Transactions of the Royal Society of South

Australia (1909), he records the original discovery

(attributed to his wife) as occurring, at the end of

September, 1908. He based his determination of the

species on half a dozen withered specimens which he

thought had probably, flowered in July and August.

It occurs to me that late September is a long time after

the usual flowering period of this plant (April and

May), in which; to see "withered specimens". The

Third Edition of J.N. Black's "Flora of South

Australia" (1978) does not record P. obtusa from

Kangaroo Island. I wonder; whether the good doctor

really saw the plant we know as P. obtusa, or perhaps

some other species.

Unlike our previous visit to this area in 1979, 1981 is

definitely not a vintage year for P. obtusa, having

probably been too dry. Although a number of plants

were flowering and some were in bud, many had

already wilted. They were not present in the numbers

seen in 1979. Other orchids recorded were Acianthus

exsertus in bud, and the basal rosettes of Pterostylis

spp. There was some discussion as to which particular

species the rosettes belonged to, but as P. pedunculata,

P nutans, and P. curva are known to grow here,

perhaps all were represented.

An interesting non-orchidaceous plant seen growing at

the side of the track was a Correa with greenish

flowers, probably Correa calycina.

Regrouping at the picnic area, we then travelled across

the top of the range to Knott Kill in Kuitpo Forest. The

views along the way, through wide valleys to the plains

and the sea beyond, were quite beautiful. However,

although a large part of the way was tree-lined and

through bush land, the greater part of the journey was

over unsealed roads, and tail-enders in the convoy

were more concerned with seeing through the dust than

looking at scenery.

Knott Hill is a favourite venue for members interested

in rare and uncommon species, and has been visited on

several previous occasions. \

This time, we found plenty of flowering specimens of

Leporella fimbriata, Prasophyllum rufum in smaller

numbers, and what must have been the last flowering

plants of Eriochilus cucullata for this season, while

basal leaves of Lyperanthus nigricans and Thelymitra

spp were recorded. Unlike 1979, however, a diligent

search failed to uncover basal leaves of Acianthus

caudatus, A. reniformis, Caleana major or Paracaleana

minor. The area is now somewhat over-grown making

the search difficult, but maybe the season has been just

too dry.

Bob Bates pointed out that since the Leporella is

pollinated by a male bull ant, and these insects only –

emerge under the right conditions of temperature and

humidity, the flower must remain open for an extended

period of time if pollination is to be effected. This is

fortunate for people like ourselves who like to seek

them out.

Probably the most conspicuous non-orchidaceous plant

flowering here was Correa reflexa, its red bell shaped

flowers being infinitely more visible than the Correa

sp. growing at Hindmarsh Falls.

All in all, we enjoyed quite a successful excursion on a

beautiful day, undertaken in an unhurried, even

leisurely fashion, which suited the balmy weather, and

seemed to suit the general inclination of most of the

members present.

A NOTE ON GREENHOOD TAXONOMY

LEO DAVIS

Bob Bates has contributed thoughtful, informative

articles to this Journal that present a strong case for the

use of a number of genera of Greenhood orchids.

These propositions seem soundly based to this amateur

field observer. His arguments, for example, that the

“Bearded or plumed greenhoods became

Plumatichilos, Shell orchids became Diplodium;

striated greenhoods became Bunochilus” just seem

good sense, (DNA and other evidence, etc., aside)

when we consider what clearly discernible

morphological differences we amateurs see in the field.

I have studied some of the published articles behind

the debate and submit my interpretive summary of the

latest published classification, as I understand it. This

places all Greenhoods into the single genus Pterostylis.

(Table below).

Janes and Duretto (2010) reject the division of the

Greenhood orchid genus Pterostylis into 16 genera by

Szlachetko (2001) and Jones and Clements (2002) and

instead propose a single Pterostylis genus comprising

two subgenera (Pterostylis and Oligochaetochilus)

within which they set up 10 Sections.

Janes et al (2010) “concluded that the generic concepts

proposed by Szlachetcho (2001) and Jones and

Clements (2002b) were questionable”.

I suggest that even if Janes and Durettos’

interpretations of literature and data are correct, that is

not sufficient reason not to consider a rational division

of the large and highly diverse genus Pterostylis. A

cursory glance at the table above suggests the

possibility of setting up at least two genera (Pterostylis

and Oligochaetochilus) or, alternatively, up to 10

genera (which, according to Janes et al, would spread

what I like to call Oligochaetochilus species across 5

different genera!). Both these possibilities would be

consistent with the DNA results reported by Janes et al

(2010).

But I’m surrendering. Out in the field, where nobody

knows, I’ll continue to seek out and identify

Bunochilus, Diplodium, Hymenochilus,

Oligochaetochilus, Plumatichilos, Urochilus, etc.,

plants but in public I’m going to be a Pterostylis man

all the time.

INCORRECT IDENTIFICATIONS

Rob Bates

DL Jones’ Native Orchids of Australia (2006) is an excellent book and is certainly my main reference on Australian

orchids. However, the following SA orchids have the wrong species shown in their illustrations

1. Petalochilus prolatus: page 40 shows a pink flowered Caladenia with tall labellum side lobes. True P.

prolatus as shown in Orchids of SA is always white flowered.

2. Corysanthes expansa: the image on page 171 is one of the many forms of C. despectans. For true C.

expansa see Orchids of SA.

3. Corunastylis tepperi: the image on page 189 is acceptable as C. tepperi, but as this species is based on

material from South Australia it would have been better to have chosen an image from SA.

4. Prasophyllum constrictum: is a mallee species so it is hardly useful to show an image of Prasophyllum

species Bushfires from near Mt Lofty (page 206) as an illustration of it. Similarly the image of P. pruinosum

on page 212 is hardly a good example of the species.

a. Prasophyllum fecundum R Bates: on page 218. The image used here is P. sp Enigma.

b. Prasophyllum calcicola R Bates on page 219 is a species based on South Australian material and

the WA image used is very different from P. calcicola in the true sense.

5. Microtis: the images used to illustrate SA and WA species are often way off the mark. M. familiaris R

Bates from WA for example is a species with the lateral sepals clasping the ovary which is not the case in the

image used on page 224. It is clearly M. brownii.

a. M. graniticola R Bates on page 225 is a species with a very large labellum whereas the image used

shows flowers with affinities to M. eremaea R Bates and nothing like graniticola.

b. Likewise with Microtis oblonga on the same page. This species, based on Victorian material, has a

long slender labellum nothing like that of the NSW specimen illustrated.

c. On page 227 the image of a woodland plant purported to be the waterhole species M. quadrata R

Bates is a very poor match.

I admit that Microtis is a difficult genus to work with, but poor images of the wrong species will not help

anyone to work out the genus.

6. Thelymitra images are much better, but I do have a problem with the use of a Tasmanian plant to illustrate

the SA species T. bracteata especially as the image on page 234 is nothing like the real T. bracteata.

7. Calochilus images are great but somewhat misleading on all SA forms. The concept of accepting C.

imberbis as a species but ignoring SA’s C. cupreus is mystifying. Also the use of an Adelaide Hills

woodland image of C. platychilus to illustrate C. robertsonii on page 262 when true C. robertsonii is a heath

land species based on plants from SW Victoria is not at all helpful.

8. Oligochaetochilus: images of South Australian species were most unimpressive especially O. ovata which

showed nothing of the species’ special features. Otherwise the Pterostylis in general are well done.
