HYMENOPHYLLUM CILIATUM. 



SwARTZ. Hedwig. Willdenow. Hooker. 



(Not of SCHLECHTENDAL.) 



PLATE LXIX. C. 



Hymenophyllum — Membrane-leaved. Ciliatum — Hairy. 



A STOVE Fern from the West Indies, Brazil, Surinam, and 

 Mexico. 



The fronds, which are bi-tripinnatifid, are somewhat oblong- 

 ovate in form, the segments linear-obtuse, hairy throughout, 

 especially along the margin of the fronds, and on the costa. 



Stipes mostly brief, but varying in length, winged, sometimes 

 almost to the base. 



Fronds ranging from two to six inches in length. 



Involucres broader than the segments, suborbicular, obliquely 

 cordate at the base. 



Similar in habit to Hymenophyllum chiloense of Hooker, but 

 double the size. Fronds dense. 



Requires a very humid atmosphere, ranging in temperature 

 from 50° to 75°. 



I am indebted to Mr. J. Smith, Curator of the Royal Gardens, 

 Kew, for the plant illustrated.
