The genus Wrightia R. Br. was last revised by Ngan (1965) who recognized 23 species and several subspecies. Since then a small number of additional species have been described (Bahadur and Bennet, 1978; L´ y, 1985; Middleton and Santisuk, 2001) from India, Vietnam, and Thailand. The genus is here revised for the forth- coming Flora Malesiana account of the Apocynaceae, subfamilies Rauvolfioideae and Apocynoideae (sensu Endress and Bruyns, 2000). Eight species are recognized, one of which has two subspecies. A new species from recently collected material in Palawan is described, and the status of some of Ngan’s sub- species within Wrightia pubescens are reassessed. Ngan (1965) has given a very good and thorough assessment of the morphological characters in Wrightia. The genus shows some interesting biogeo- graphic patterns in Malesia. Most curious is the complete absence of any collections of the genus from Borneo, despite the widespread distribu- tion of taxa like Wrightia laevis and Wrightia pubescens subsp. lanitii in the surrounding regions. There are two species, Wrightia hanleyi and Wrightia palawanensis, endemic to Palawan in the Philippines, and another, Wrightia can- dollei, more widespread but still endemic to the Philippines. Wrightia novobritannica is known only from one collection from the Papua New Guinea Island of New Britain and would appear to have similarities to Wrightia candollei.

Abstract. The genus Wrightia is revised for the Malesian region. Eight species are recognized, one of whichhas two subspecies. One new species, Wrightia palawanensis, is described, and one new combination, Wrightianovobritannica, is made. A key to the species is given, and the taxa are described. Lectotypes and neotypes aredesignated for a number of names.

Keywords: Apocynaceae, Apocynoideae, revision, Wrightia, Malesia.

This species was included as a subspecies ofWrightia pubescens by Ngan (1965), but it dif-fers substantially from that species in the shapeand form of the corolla and corona and in theflower color. Therefore, it has been raised backto specific level.

Wrightia laevis is an extremely widespreadand variable species. Ngan (1965) recognizedthree subspecies across this range on the basis ofcorona and inflorescence pubescence charac-ters, for which I have been unable to find cleardemarcations. I am not, therefore, recognizing

the subspecies. However, the specimens fromNew Guinea in fruit show a shorter and widerfruit type than is found in the other parts of therange, and the trees are reported as much taller.In flower they are unremarkable except for theextremely long and fine corona lobes of the for-mer subsp. novoguineensis. This variation doesnot, however, correspond to the limits of any ofthe former subspecies and is not the basis forrecognizing any formal ranks.

Inflorescence termi-nal, 2- to 5-flowered, 1–4 cm long; peduncle0.2–1.4 cm long, glabrous; pedicels 5.5–7.0 mmlong, glabrous. Sepals ovate, 1.9–2.1 × 2.4–2.9mm, 0.7–0.8 times as long as wide, apex obtuseto rounded, glabrous, ciliate. Corolla salmonpink or yellow, infundibuliform; tube 3.8–4.0mm long, widening at stamen insertion, 1.8–2.1times as long as sepals, 0.4–0.5 times as long aslobes, sparsely and minutely puberulent at topof tube outside, glabrous inside; lobes 8.5–8.9 ×7.0–7.7 mm, 1.1–1.3 times as long as wide,elliptic, apex rounded, minutely puberulent out-side and inside; antepetalous corona lobesadnate to the corolla lobe for entire length butfree at margins, 4.3–4.5 mm long, apex suben-tire to weakly crenate, glabrous inside, ca. 6times as long as alternipetalous lobes;alternipetalous corona lobes free but often sosmall as to be difficult to see, simple, 0.7–0.8mm long; alternating corona lobes lacking.

Stamens inserted at ca. 0.7 of tube length fromcorolla base, exserted from tube; filament ca. 1mm long; anthers 5.0–7.1 × 1.1–1.7 mm, sagit-tate, adnate to the style head, pubescent on theoutside only at the very tip. Gynoecium of 2free carpels united into a common style, ovaries1.7–2.2 mm high, glabrous; style and style head3.0–5.5 mm long. Fruit unknown (see notes).

Distribution: Philippines (Palawan).Habitat: reported from riverine and mixed

forest and from ultramafic soils at 100–200 maltitude.

Etymology: the specific epithet refers to thedistribution of this species in Palawan.

Additional collections studied: PHILIP-PINES. PALAWAN: Bataraza Munic., Bgy RioTuba, Belanjao Range, Gamayon Settlement,Soejarto et al 8402 (L); Brookes Point munici-pality, ca. 15 miles N, Infanta mining area,Podzorski SMHI 2156 (A, L).

This new species would appear to haveaffinities to Wrightia hanleyi Elmer, but it haslarger flowers and the stamens are insertedhigher in the corolla tube. It differs fromWrightia candollei Vidal in the free carpels andthe lack of pubescence on the outside of theanthers. None of the specimens report the pres-ence of white latex, but it would be surprisingif this were not present. I have not seen anyfruit, but they are reported on one specimen tobe paired.

There are a number of specimens of this sub-species where the fruit is very short and rathermisshapen. The dimensions are not included inthe description above as I suspect insect dam-age in the formation of the fruit.

Wrightia pubescens ssp. lanitii would appearto be as different from ssp. pubescens as ssp.candollei, which has been resurrected as a

species distinct from Wrightia pubescens.Wrightia pubescens ssp. lanitii and ssp. pubes-cens differ in the size and shape of the sepalsand, for the most part, the pubescence of theantepetalous corona lobes. However, there areindividuals that have some pubescence on theinside of the corona lobes, and specimens fromSulawesi have the corona type and sepal shapeof ssp. pubescens but the sepal size of ssp. lan-itii. Because of these intermediates and thegreater similarity in corolla shape and sizebetween these two subspecies compared to ssp.candollei, they are being maintained as sub-species, whereas Wrightia candollei, which isalso sympatric with W. pubescens ssp. lanitii,has been given specific status.

Distribution: Thailand, Cambodia, possiblyPeninsular Malaysia. The natural distributionof this species is now obscure because it is sowidely cultivated, but is probably Thailand andmaybe Cambodia. It may also be native inPeninsular Malaysia, but is certainly widelycultivated in many parts of Malesia.

NOTE

Wrightia timorensis Miq., Fl. Ned. Ind. 2: 433.1857. TYPE: TIMOR. Sine loc., Unknown s.n.(Lectotype: L [898,112–484]; Isotype: U [frag-ment]).

Wrightia timorensis is a synonym of Wrightiatinctoria, a species otherwise known only fromIndia. Its appearance in Timor is a mystery andis likely to be either a mistake on the label or

else a cultivated plant transported from Indiaearlier. There are no notes on the label to indi-cate whether it was a cultivated plant. Untilsuch time as further material is collected inTimor that matches this specimen and its statuscan be reassessed, I am not including this as aMalesian species to be discussed further.
