360 Transactions. — Botany, 



aid of a good glass, the stellate tomentum that so closely envelopes this 

 singular plant presents a most curious and interesting appearance. We 

 have collected this Hymenophylluvi in the bush above Port Levy and Pigeon 

 Bay, sometimes growing in company with a small form of H.. bivalve. 



Ehizome slender, creeping, rough, fulvous, with a few scattered tawny 

 scales, or hairy. Stipe, base gibbous, tomentose, long, slender, 2-3 inches 

 long; upper portion immediately below the rachis densely tomentose. 

 Fronds pendent, narrow-oblong, 2-6 inches long, 1-1^ inches broad, 

 bi- tri- or quadripinnatifid ; covered above and beneath with a close 

 tomentum ; upper surface greyish-green to buff, dull reddish-brown 

 beneath. Divisions long, narrow, almost terete ; sori terminal on the 

 segments, clothed with shaggy hairs, rather dark buffish-brown ; the whole 

 frond coriaceous, stiff, rather harsh to the touch. 



In the " Synopsis Filicum" it is placed next to a South American fern, 

 H. sericum, with which it is said to be closely connected. In Hooker's 

 " Handbook of the New Zealand Flora" it was grouped with Trichomanes. 

 Trichomanes venosum, Br. 



On the rhizome of Todea hymenoijhylloides ; on the stems of tree-ferns, 

 such as Hemitelia smithii, Dicksonia squarrosa ; in the bushes of Banks 

 Peninsula, including the Port Hills. 



Cystoi^teris frayilis, Bern. 



On grassy terraces near the gorge of the Eakaia river ; in Mount Guy 

 valley in the Upper Ashburton district ; Eiver Havelock, Upper Eangitata ; 

 on the lower spurs of Mount Herbert, Banks Peninsula. Altitude of 

 habitat varying from 500 feet to about 2,500 feet. 



Adiantum diajyJianum, Blume (?). 



In the gorge of the Eakaia river the writer collected an Adiantum which 

 is probably A. diaphanum.. It differs somewhat from the diagnosis given in 

 Hooker's and Baker's " Synopsis Filicum." Should it prove to be A. 

 diaiolianum, this subalpine habitat is worth recording. The rock from 

 whence it was taken is about 900 feet above sea-level. Stipe slender, 

 polished, blackish, 3-4 inches long. Frond — 4-6 inches long, 1-li 

 inches broad; simply pinnate, rarely with one feeble branch at the 

 base ; pinnules ^-1 inch broad, J-f inch deep ; lower margin decurved ; 

 upper and outer line cuneate, texture thin, surface on both sides naked. 

 Sori few, not contiguous. 



Pellcea falcata, Br. 



Amongst dry rocks, in bushy ravines, on slopes of Dun Mountain, 

 Nelson. 



Lorn aria duplicata, Potts. 



On referring specimens of this fern to the authorities at Kew, it was
