deducted as doubtful natives. In addition a few other species have been gathered as strays from garden cultivation. R. cia- namomea, L., found by Mr. Sabine long ago near Pontefract, is frequent in gardens, and widely dispersed as a native plant in continental Europe. R. lucida, Ehrh., found by Mr. Borrer near Keswick (Phyt. ii. p. 437), and by Mr. Reeves near Tunbridge Wells, is a common North-American rose, also frequent in gardens. The same plant has been gathered in a subspontaneous state in France and Germany, and is R. baltica, Roth (Enum. ii. p. 464 ; Koch, Syn. p. 444). The subspontaneous Porkshire and Sussex Roses, mentioned by Mr. Borrer in the ( British Flora,’ 3rd edit. p. 245, do not appear to be essentially different from R. provin- cialis, Ait. j and the R. amensis, var. Andersmi, mentioned by Smith, ‘Eng. Flora,’ ii. p. 398, I believe to be R. austriaca, Crantz. The two latter are both members of the Qallicaram group.

Notes on the Stictei in the Kew Museum. By CHABLEH KNIQHT, Esq., F.L.S.

[Read April 15, 1869.1

DR. NYLANDER arranges the Stictei under three genera-Stictina, Sticta, Xicasolia. An examination of these lichens in the Kew collections shows that this distinguished lichenologist, in his ( Synopsis Methodica Lichenum,’ has not in every case arranged the species in accordance with his own scheme of classification.

The essential distinctive characters which separate Stictina ~ from Sticta depend on differences in the colour and structure of

the gonidial cells. In the genus Sticta the gonidial layer con- sists of free cells and hyaline filaments; and each cell contains bright green protoplasm. I n Stictina, on the other hand, we find in the gonidial layer irregular-shaped cellular “ nodules,” in the cells of which are imbedded two or more bluish granules (granula gonimrt) .

Stictina faveolata (Nyl. Syn. p. 337). The numerous specimens in the Kew Collections, whether

named by Babington or Nylander, belo’ng to the genus Sticta, with the exception of Lechler’s plaut no. 598 c. “Sticta cervicornis 13. atrovirens, Flot.,” and another from the Paris Museum ticketed (‘ Sticta fnveolata :” thesc two plants being identical, it would

241 MR. C. EYIQHT ON THE STICTEI

be convenient to retain the name Stictina cervicornis ; the others will be referred to the genus Sticta under the name of Sticta f a - ueolata.

Stictina carpoloma (Nyl. Syn. p. 339). The lichens arranged under this name in the Kew collections

must be referred to the genus Sticta, with the exception of two specimens-one (Stictinn gilva) collected by Lyall in the Falk- land Islands, and the other (also Stictina gilva) collected by Dr. Mueller in Victoria (no. 154). As far as one can determine from the Kew collections, which are extremely rich in specimens, S. yilva has been mistaken for 8. caqnoloma.

Dr. Nylander, in his ' Synopsis,' quotes as synonyms of S. carpo- loma, Wl., the S. Desfontainii, DB1, and S. gyrosa, Flot. (Lechler's P1. Yacleov. no. 66). The specimens of S. Desfontanii in the Kern Museum (no. 562, Lechl. P1. Chilenses) are widely different from S. carpolomn; and those of S. gyrosa from the Falkland Islands bear no resemblance whatever to it.

Stictina granulata (Nyl. Syn. p. 340). These, Dr. Nylander has since found, belong to the genus

Sticta retigera (Nyl. Sgn. p. 351). Belongs to the genus Stictina.

Sticta.

There are numerous specimens in the Kew Museum, chiefly arranged under Sticta pulnzonacea.

Sticta linita (Nyl. Syn. p. 353). Several specimens arranged under this name in the Kew Mu-

Beurn belong to Stictina. They differ from Stictina retigera and S. scrobiculata in having white powdery pseudocyphellae, and from Stictapulmonacea and S. linita in having the gonidial layer made up of bluish " granula ganima " instead of true gonidia. I have named them Stictina reticulata.

Sticta scrobiculata (Nyl. Syn. p. 353). nr. Nylander has lately correctly referred it to Stictina.

Sticta dammcornis, var macrophylla, D61. (Nyl. Syn. p. 366). The plants collected in the Mauritius by Dr. Ayres, and the

Sticta specimen from Mus. Hist. Nat. Paris, belong to Stictina. mmrophylla, Schaer., will stand as a variety of S. dammcornis.

Xticta obvoluta (Nyl. Syn. 11. 362)). Belongs to thc geiius Stictiitn.

I N THE KEW MUSEUM. 245

There seems to be some confusion in reference to the syno- nyms in Nylander’s ‘ Synopsis,’ under S. gynlocarpa and S. Kunthii (p. 342). I suspect it will be found that S. cyathicarpa, DBl., be- longs to S. gyalocarpa, Nyl.

Sticta Guillemini (Nyl. Syn. p. 362). Is also a Stictina. There is, however, a pretty, fawn-coloured,

delicate lichen, referred by Babington to 8. Guillemini, Mont. It is a true Sticta, with large gonidia, the thallus above covered with soft white hairs, pseudocyphell~ citron-colour, apothecia pedicel- lated, scattered, and the thalline receptacle hairy.

Stictapunctulata (Nyl. Syn. p. 364). The specimen collected by Dr. Maxwell in Ceylon and named

by Dr. Nylander is a Xticfina. There is another specimen, how- ever, also collected in Ceylon, but a. much more robust plant, referable to the genus Sticta.

Sticta endochrysea (Nyl. Syn. p. 358). This plant and the synonyms are correctly placed in Dr.

Nylander’s work. In all the specimens in the Kew Museum the thallus is covered with a most minute tomentum, as well as the thalline receptacle of the apothecia. But there is another species, curiously like the S. endochrysea, belonging to the genus Stictina, with the inner layer of the thallus yellow, the thallus most minutely tuberculated, and the spores acicular. The plants belonging to the latter are Lechler’s pl. 662, “Sticta Desfontainii,” and Gay’s plant “S. d’Urvillei, DQI. (8. orygmffia, Mont.),” from the Pans Museum.
