 G9. II. cxscrliim. Wall. ; flexile pendent, fronds oblong 

 elongate acuminate pinnated, pinna; rather distant lanceolate 

 acuminate decurrent especially the upper ones pinnatifid but 

 not dcejdy, segments short linear-oblong obtuse entire sim])le 

 or bifid, involucres on the upper side of the pinnaj solitary or 

 2 — 3 sessile or terminating short segments ovate 2-valved al- 

 most to the base compressed, the valves eroso-serrate or near-

 scattered rufous hairs. (Tab. XXXVIII, k.)^Wall. Cat. n.

 burgh, Bennett, J. D. Hooker, Duperrey. — A small, slender, graceful plant, 

 3 — 5 inches long, with a short, slender stipes and a wavy filiform rachis. 

 A well-marked species in the form of the frond, remote, narrow, cuneato- 

 pinnatiiid pinnae and orbicular and toothed valves of the involucre, which 

 latter circumstance has been entirely overlooked by Borj in the figure gi- 

 ven in Dupcrrey's Voyage. 



71. H. demissum, S\v.; tall erect elastic, fronds ovato-acu- 

 minatc pinnate, rachis winged above, ])inna) bi-tripinnatiiid, 

 the segments linear obtuse entire ])ointing upwards, ultimate 

 ones irequently elongated, involucres on the lateral segments 

 small ovate sessile 2-valved to the base compressed, stijjes 

 terete smooth. — Sw. Syn. Fil. p. 147 and 374. Sc/tkr. Fit.
