 ft. 1., 12-15 in. br. ; pinrKB 6-8 in. 1., |-| in. br. ; cut two-thirds of the way down

 racfiis and both sides nearly naked ; veinlets 10-12 on a side ; sori near the 

 midrib. — Aspidium, Wallich. 



Hab. Malayan Peninsula. — This comes very near the last, hut is nearly naked and 

 more deeply cat, with the sori in a diSerent position. 



174. N. kirsutum, J. Sm. ; «J. 1 ft. or more 1., grey, villose ; /r. 3-4 ft. 1., 

 1^ ft. br. ; pinncB very close and numerous, spreading, the largest 10 in. 1., 

 f in. br. ; cut down halfway to the rachis into entire, Unear-oblong, subfalcate 

 lobes ; the lower ones with a gland beneath at the base ; texture subcoriaceous ; 

 rachis densely clothed with soft spreading hairs ; under surface glandular ; 

 veins 6-8 on each side ; sori medial. — Hi. iSp. 4. p. 70. t. 240. B. {not Don).

 A. venulosum. Wall. A. obscurum, £1. 



Hab. N. India, Philippines, Malayan Peninsula. — This differs from the three preceding 

 by the under side being nearly or quite naked, and in the position of the sori. A . callosum, 

 Blume, quite agrees with this, except that there is a large prickle-like gland at the base 

 of the pinnae, and sometimes also of the veins.

 largest 8-9 in. 1., 1 in. br., cut, down halfway to the rachis into slightly-toothed 

 oblong lobes ; texture subcoriaceous ; both surfaces naked ; colour bright-green ; 

 veins about 9 on each side, conspicuous above, with a sorus on each midway to 

 the edge. — Hk. Sp. 4. p. 71.
