throughout and also conspicuously ciliated with stellate hairs. 
Primary pinne oblong or rhomboidal, cut down to a broad central 
portion into numerous secondary divisions, which are simple or 
forked or irregularly pinnatifid. Ultimate segments linear, flat, 
obtuse, quite entire. Sori numerous, terminating the segments,

Sour Istanp: Nelson— Travers (Handbook). 
An abundant plant throughout the whole of tropical America, from Cuba 
and Mexico to Chili; also in tropical Africa, Madagascar, and Mauritius. I 
have seen no New Zealand specimens, the plant not having been refound since 
its original discovery by Mr. Travers nearly forty years ago. 
13. H. subtilissimum, Kunze, Anal. Pteridog. 50.— Forming 
dense mats on the stems of fern-trees and on tree-trunks, or on the

3-2 in. broad, ovate-lanceolate or lanceolate, acute or acuminate, 
very thin and membranous, yellow-brown or tawny, usually pen- 
dulous, 2—3-pinnatitid, everywhere clothed with copious silky 
stellate hairs. Stipes filiform, not winged; rhachis narrowly 
winged above, wingless below. Primary pinne short, erecto- 
patent, ovate-lanceolate, cuneate at the base; secondary irregu- 
larly pinnatifid or forked. Ultimate segments close, linear, obtuse, 
flat, quite entire. Sori numerous, small, terminal, sunk in the tips 
of the lateral segments. Indusium orbicular or broader than long, 
2-valved almost to the base; valves rounded, copiously ciliated
