 of that species and H. calathina. Bulb with a long neck : 

 Ivs. 8-9, oblanceolate and bright green, 2-3 ft. long: fls.

HYMENOSPORUM 



linear-lanceolate, a little longer than the tube. B.M. 

 6436. Gn. 18:211. Blooms in Feb. and Mar. One of the

HYMENODIUM. See Acrostichum. 

 HYMENOLEPIS, See Acrostichum . 



HYMENOPHYLLUM (Greek, membrane-leaved). Hy- 

 menophylldcece. A large genus of filmy ferns allied to 

 Trichomanes, but having a more or less deeply 2-lipped 

 or 2-valved involucre. Some 80 species are found in the 

 tropics of both hemispheres. One species appears in 

 wells in England. 



Hymenophyllum demissum is a difficult plant to gro\ 

 It needs a Wardian case in a coolhouse, and occasion! 

 sprinkling overhead. The members of this genus 

 propagated slowly by division.

pinnatifid; sori very numerous, 20-30 to a pinna; invc 



lucre with ovate entire valves. E. Indies to New Zealanc 



AA. Lvs. pubescent or ciliate. 



ciliatum, Swz. Fig. 1116. Stalks ciliated and winj 

 above : Ivs. 2-6 in. long, 1-2 in. wide, tripinnatifid, tl 

 segments ciliated ; involucre roundish, the valves 

 vided half way down and ciliated. Tropics of both hei 

 ispheres. 



aerugindsum, Carm. Fig. 1117. Stalks tomentose : lv 

 2-3 in. long, 1 in. or less wide, tripinnatifid, the pin'i 

 often imbricate, the surface and margins densely pi 

 bescent ; involucres small, with valves divided

 seeds which distinguish it from Pittosporum). Pitt
