1, H. rarum R. Br. Prody. (1810) 159.—A very delicate pale glistening- 
green pellucid species, forming matted patches on the trunks of trees or 
on rocks. Rhizomes creeping, much branched, very slender, wiry, black. 
Fronds very variable in size and shape, usually from 1-4 in. long, but 
sometimes dwaried to 4in., and occasionally lengthened out to 6 or Sin., 
broadly oblong to linear-oblong, 2-pinnatifid, in large specimens pinnate 
at the base, pendulous, membranous, flaccid, quite elabrous. Stipes 
extremely slender, capillary, often half the length of the whole frond: 
main rhachis usually winged throughout. Pinnae close, often overlapping, 
one or twice eas ced or pinnatifid, “rarely y simple. Seoments erecto-patent, 
+-4 in. long, 4, in. broad, flat, obtuse, quite entire. “Ser mostly near the 
dart of the frond, sunk in the tips of the segments. Indusium large, 
almost as broad as the segments, broadly rhomboid, divided half-way 
down, cuneate at the base: valves broad, rounded.—Hook. Sp. Fil. 1
