Art. LX.—Notes on Plants from Campbell Island.

[Received by the Wellington Philosophical Society, 13th March, 1882.]*

Having had the privilege of examining the collection of Campbell Island plants in the Otago Museum, and comparing it with a set presented to me by the same collector, Dr. Filhol, also with a small collection made by Lieutenant Rathouis, of the “Vire,” I find several interesting plants not previously known to exist on the island. I have therefore drawn up the following list of the plants comprised in the three collections, and added a few critical notes:—

Ranunculas pinguis, Hook. f. All the specimens with solitary flowers, and the leaves much more succulent than in alpine specimens from the South Island.

R. aucklandicus, Gray. Occurs in all the sets. Petals small, distant.

Cardamine hirsuta, L., var. carnosa.

Stellaria decipiens, Hook. f. In the Otago collection only: a mere fragment without flowers.

Colobanthus muscoides, Hook. f. A scrap mixed with Tillæa—Lieutenant Rathouis.

Montia fontana, L.

Acæna sanguisorbæ, Vahl. A form clothed with soft silky hairs.

Tillæa moschata, DC.

Epilobium linnæoides, Hook. f. In all the sets. This plant must be considered a form of E. rotundifolium, from which some of the present specimens cannot be distinguished.

E. confertifolium, Hook. f. A small form which may prove to be specifically distinct. It occurs at from 4,000 to 5,000 feet in Marlborough and Otago.

Ligusticum latifolium, Hook. f. In all the collections, but it is worthy of note that L. antipodarum is not represented in either.

Stilbocarpa polaris, Dcn. and Planch. Sir Joseph Hooker has pointed out the differences between specimens of this plant from the Auckland Islands and Stewart Island. Those from the Auckland and Campbell Islands have the leaves plaited and clothed with strong hairs. I have been much interested in observing that of three specimens from the Auckland Islands cultivated in the Wellington Botanic Garden, side by side with a strong specimen from Stewart Island, two have entirely lost these characters and exactly resemble the latter. There is, moreover, no difference in the inflorescence of plants from the two habitats, and both alike give off strong scions.

Celmisia verbascoides, Hook. f. The occurrence of this grand Otago plant on Campbell Island is of considerable interest. The flowers are rather larger than in specimen from the Horse ranges.

C. vernicosa, Hook. f. The specimens have the ligulæ of the ray-florets whiet, not rose-coloured at the tips as represented in Flora Antarctica. In this respect it agrees with all the species of the genus, but differs in having disc-florets of a deep purple colour.

Pleurophyllum speciosum, Hook. f.

P. criniferum, Hook. f. Imperfect specimen only.

Cotula plumosa, Hook. f.

Gnaphalium prostratum, Hook. f. The specimens in the different sets show that G. bellidioides cannot be separated from this species. A complete transition may be seen from the short leafy branch terminated by a sessile head of G. prostratum, to the elongate slender peduncle of G. bellidioides.

Dracophyllum urvilleanum, A. Rich., var. scoparium.

D. longifolium, Hook. f. Otago collection only.

Veronica benthami, Hook. f.

Caladenia bifolia, Hook. f.

Anthericum rossii, Hook. f. Specimens of A. hookeri, from Lake Harris, exhibit a marked approach to the diœcious condition characteristic of A. rossii

Lazula crinita, Hook. f.

Isolepis aucklandica, Hook. f.—Lieutenant Rathouis.

Oreobolus pumilis, R. Br.

Carex appressa, Br. A small form; the panicle less than two inches in length.

C. trifida, Cav.

Poa foliosa, Hook. f. The typical form recorded by Mr. Buchanan from the Snares and from the Chatham Islands, in the latter case incorrectly, Festuca scoparia, which is omitted from his list of Chatham Island plants, having been mistaken for it.

Hymenophyllum multifidum, Swartz.

Hypolepis millefolium, Hook. f. With some hesitation I refer a sterile specimen collected by Lieutenant Rathouis to this species; it may, however, prove to be a finely cut form of Polypodium rugulosum.

Pteris incisa, Thunb.

Lomaria capense, Willd.

L. dura, Moore. In all the collections and apparently attaining a large size.

Aspidium aculeatum, Swartz, var. vestitum. The specimens are of more rigid texture than any I have seen from either the North or South Island.

Polypodium rugulosum, Lab. A large viscid form of unusually stout texture. Lycopodium billardieri, Br., β. vatrium. One specimen is an intermediate form; the others belong to the robust form commonly known as L.

varium, Br.

Dicranum billardieri, Brid.

" setosum, Hook. f. and Wils.

Campylopus appressifolius, Mitt.

Ceratodon purpureus, Brid.

Polytrichum tortile, Swartz.

Hypnum serpens, L.

" adculare, Lab.

" chlamydophyllum, Hook. f. and Wils.

Jungermannia monodon, Hook. f. and Tayl.

Marchantia tabularis, Nees.

Cladonia pyxidata, Fries.

" gracilis, Hoffm.

" furcata, Hoffm.

" rangiferina, Hoffm.

" aggregata, Eschw.

" retipora, Flœrke.

Stereocaulon ramulosum, Ach.

Stica filicina, Ach.

" variabilis, Ach.

" fossulata, Dufour.

Polysiphonia dumosa, Hook f. and Harv.

Polyzonia cuneifolia, Mont.

Dumontia filiformis, Grev.

Codium tomentosum, Agardh.
