Gramine^. 

 Banthonia raoidii, Steudel, var. australis ■ J. Buchanan, Trans. N.Z. Inst., 

 IV., p. 224. 

 South Island — Kaikoura Mountains ; Lake Guyou, Nelson. 



Danthonia semi- annular is, Br., alpina; J. Buchanan, Trans. N.Z, Inst., 

 IV., p. 225. 

 South Island — Wahau Vtdiey ; Amuri 3,000-5,000 feet ; Dusky Bay. 

 A remarkable plant, seldom flowering ; most probably a distinct species. 



Arundo conspicua, Forst., var. fulvida. 



A. fulvida, J. Buchanan ; Traus. N.Z. lust., p. 242. 

 North Island — Poverty Bay ; Port Nicholson. South Island — Mataura

FiLICES. 



Dicksonia antarctica, Br., var. fibrosa. 



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

 p. 46i. 

 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., IL, p. 10. 



HymenojjhyUum cheesemannii, Baker, Synopsis Filicum (2ad edition), 

 p. 464 ; Cheeseman, Trans. N.Z. Inst., VIII., p. 329.

Hymenophyllum armstrongii, Kirk. 



Trichomanes armstrongii, Baker, Sjn. Fil. (2nd edit.), p. 464 ; Armstrong, 

 Trans. N.Z. Inst., IV., p. 291 ; Kirk, Trans. N.Z. Inst., X., pi. XXI. A. 

 also p. 532. 



This minute plant is a true Hymenojihyllum, the involucres being dis- 

 tinctly 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 

 ixom.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 pinna, 

 enlarged ; 4 and 5, sori, greatly enlarged.
