Filices.

Dicksonia antarctica, Br., var. fibrosa.

D. fibrosa, Col. in Tasmanian Journal; Baker in Synopsis Filicum (2nd edit.), p. 461.

This differs from ordinary forms of the Australian and Tasmanian plant, in its smaller size, hairy rachis, more compact habit, and less coriaceous texture, but these are not characters on which specific distinctions can be based, so that I am unable to accept Mr. Baker's opinion as to its specific validity. See Sir Joseph Hooker's emphatic remarks on this species, Fl. N.Z., II., p. 10.

Hymenophyllum cheesemannii, Baker, Synopsis Filicum (2nd edition), p. 464; Cheeseman, Trans. N.Z. Inst., VIII., p. 329.

North Island— Amongst moss on trees, Whangarei; Great Barrier Island; Titirangi; Hunua; Thames Goldfield.

Hymenophyllum armstrongii, Kirk.

Trichomanes armstrongii, Baker, Syn. Fil. (2nd edit.), p. 464; Armstrong, Trans. N.Z. Inst., IV., p. 291; Kirk, Trans. N.Z. Inst., X., pl. XXI. A. also p. 532.

This minute plant is a true Hymenophyllum, the involucres being distinctly 2-valved and divided to the base when mature. They are much compressed, especially in the young state, and the lips have a broad margin, but there is no constriction; occasionally the lips of the valves are slightly recurved after the discharge of the spores. It can only be distinguished from H. cheesemannii by the stout marginal nerve and firmer texture; the involucres are not constantly ciliated.

It forms matted patches on rocks, or occurs more sparingly amongst moss on trees, so that, like the preceding, it is easily overlooked.

Plate XXI. A., 1 and 2, Hymenophyllum armstrongii, natural size; 3, fertile pinns, enlarged; 4 and 5, sori, greatly enlarged.

South Island— On rocks, Upper Waimakariri; Bealey; Arthur's Pass; on trees, Hokitika; Okarita; sea-level to 4,000 feet. I am indebted to Mr. A. Hamilton for my knowledge of its occurrence at Okarita.

Hymenophyllum villosum, Colenso; Kirk, Trans. N.Z. Inst., X., p. 395.

North Island— Ruatahina; Tarawera. South Island— From Marlborough to Otago, 2,000-4,000 feet.

Hymenophyllum montanum, Kirk; Trans. N.Z. Inst., X., p. 394, pl. XXI. B. South Island— Lake Wakatipu.

Davallia forsteri, Carruthers; Baker in Syn. Fil. (2nd edit.), p. 470.

“Allied to D. scoparia, but with the sori smaller and bordered.” (Baker.) Only known from Forster's original specimen in the British Museum.

South Island— Dusky Bay.

Lindsaya viridis, Colenso, Tasmanian Journal; Baker, Journal of Botany, vol. IV. (1875), p. 108; Kirk, Trans. N.Z. Inst., X., p. 396.

North Island— Port Fitzroy; Manukau; Te Whau; Mangarewa; Wanganui. South Island— Massacre Bay; Hokitika; West Coast of Otago.

Dr. von Haast informs me that he has never collected this species in Canterbury, so that there can be no doubt that the specimens labelled “Canterbury, Sinclair and Haast,” in the Kew Herbarium, were obtained by Sinclair in the North Island.

Cheilanthes tenuifolia, Swartz; Kirk, Trans. N.Z. Inst., VI., p. 247.

Apparently confused with C. sieberi, Kunze, by New Zealand collectors, but distinguished by the triangular or rhomboid frond.

North Island— Mr. Colenso informs me that he has collected it in the Hawke Bay district. South Island— Lyttelton Harbour; mountains about Queenstown; Lake Hawea, abundant.

Lomaria duplicata, Potts; Trans. N.Z. Inst., IX., p. 391.

This is merely a branched form of L. procera, var. minor, but remarkable for its constancy. Mr. Potts points out that simple and branched fronds are produced on the same plant.

Lomaria acuminata, Baker; Syn. Fil. (edit. 2), p. 481.

Intermediate between L. attenuata, Willd., and L. lanceolata, Spreng. Kermadec Islands.

Doodia media, R. Br., var. milnei.

Baker in Syn. Fil. (2nd edit.), p. 482.

D. milnei, Carr.; Fl. Viti, p. 352.

Kermadee Islands.

Nephrodium glabellum, A. Cunn; Kirk, Trans. N.Z. Inst., X., p. 398. N.

pentangularum, Col.

This species has been confused with N. decompositum, Br., and N. velutinum, Hook.

Not uncommon.
