110 HYMENOPHYLLUM. 



I fhiJ to he always truly pinnated, llic segments more attenuated and 

 l)()intintj upwards ;" rachis" never winged, except above : but these are the 

 imly diiVerences pereeptible. Cuming's s])ecimen precisely accords with the 

 New Zealand ones. 



72. II. scubruin, A. Rich. ; rigid tall erect elastic, fronds 

 ovate acuminate pinnate, pinnie bi-tri])innatifid acuminate 

 the segments narrow-linear obtuse entire, involucres terminal 

 small ovate orbicular sessile free 2-valved to the base entire 

 or scarcely denticulate terminal on segments which are slight- 

 ly contracted at their apices, rachis (and frequently the costa)) 

 and stipes above more or less setose, below the stipes is 

 rougli.— J. Richard, Fl. Nov. Zeal. p. 90, t. 14, f. 1.

 — Although this be the //. acahrum of llichard, the involucres are in our 

 specimens more ovate than shown in his figure, and scarcely denticulate : 

 indeed the sjiecies has a very close affinity with II. dcmissum, but it is more 

 rigid, and more or less setose with harsh coarse hairs, which, under a micro- 

 scope, are curiously and beautifully jointed. When these hairs fall away, 

 as is the case on the stipes, especially on the lower portion, the surface ap- 

 pears scabrous to the eye and to the touch with copious raised points. 



73. 11. reniforme. Hook. ; small, fronds ovato-oblong pin- 

 nated rigid laxly cellular, pinnae pinnatifid decurrent, the seg- 

 ments linear emarginate or the lower ones forked entire, the 

 margins recurved when dry, involucres terminal free broader 

 than the segments reniform 2-valved to the base, stipes very 

 short terete smooth hispid with reddish deciduous hairs. (Tab. 

 XXXVIII. C.) 



llab. Peru, Mathews, n. 1783. — A most elegant and veiy distinct species, 

 growing in dense tufts, with a long creeping caudex which is haii*y as well 

 as the short stipes : the latter half an inch to an inch long. Fronds 1 — 2 

 inches long ; texture firm and rigid, but the reticulations are large in pro- 

 portion to the size of the plant. The margins are much recurved when dry, 

 so as to make the segments appear exceedingly narrow. Involucres reni- 

 form, free, sometimes with the valves a little erose. 



74. II. (jracile, Bory ; pendulous, fronds ovato-lanceolate 

 or oblong-lanceolate attenuated subbipinnate, pinnae remote 

 decurrent pinnatifid or bipinnatifid, the segments linear ob- 

 tuse frequently bifid entire, involucres subovate the cuneate 

 base lialf sunk in the frond, the valves compressed entire, 

 stipes cylindrical slender smooth and glabrous. — Bory hi

llab. Mauritius, Bory, Carmichad, liojer, Wallich. — IMy largest speci- 

 mens, including the stipes, are 8 — 10 inches long : the frond is flaccid, the 

 rachis waved, the wings above very narrow. Some states are less divided, 

 smaller, and approach the varieties of //. varum from Chiloe (the//, fuma- 

 rioides, Willd.) ^
