This is distinguished from Athyrium maximum (Don) Copel. {Asplruiutn 
maximum Don, Pro<h Fl. Nepal. (1825) 8), by the acuU^atc stipe and more or less 
aculeate rachis. Diplazium fimiihiavum is deseril)ed by both Baker and lieddome 
as having anastonmsing veins. Some of the specimens cited above are nfisdimcd 
to have spiuy stipes.

157S, Merrill 5-'iG3; Davao, Copeland 966 (f). Bolster 129, from Cagayan Prov- 
ince, Luzon, is an immature plant, which ia this species or a new one near it. 
While T nm convinced that this fern is not D. deltoideum I am by no means 
so confident that it is D. meyenianum ; if not. it should be known by Fee's ap- 
propriate name. The description of D. meyenianum contains nothing which does 
not fit this fern unless it be the texture, but it is very incomplete. The plant 
I have is a most distinct one, characterized by thin texture, conspicuous, sparse 
sori usually as near the margin as to the midrib, lowest veinlets in most speci- 
mens sterile, but iir occasional specimens all fertile and the lowest sori then 
usually diplazioid, the bases of the rachises of the pinua^ usually black, and tlie 
base of the stipe bearing copious acicnlar black palea?, unlike those of any other 
species. The pinnules are strikingly suggestive of the pinna^ of A. sorsogonense. 
The caudex is more or less erect. 
AlthouMi very distinct from any other Athyrium, this species is within itself 
very variable, and may ultimately prove to include several.
