Ilab. Jamaica, Swartz, Mcnzies. Mountains of Andinarca, Peru, Ma- 

 t/icus, H. 108<5. — Very distinct. The stipes varies from 1 — 3 inches. Fronds 

 :) — I inches long, in every part beautifully and equally undulato-crispate. 



60. H. Jaiatlicum, Spr. ; fronds ovate oblong tripinnati- 

 fid, the segments linear obtuse entire and as well as the rachis 

 undulated crisped, involucres copious upon very short lateral 

 segments orbicular convex entire or erose free 2-valved to the 

 very base, stipes with a broad wavy wing extending nearly to 

 the base. — Spreng. Si/sf. Vcf/et. iv. p. 132. Blume, Emim.

Hab. Pundowa Mountains, N. India, De Silva (Wallich). Assam, Ma. 

 for, Jenkins. Java, in mountain woods, and in the Moluccas, Blume. — This is 

 well llfjuredby Nees and Blume in the work above quoted, though the fronds 

 are a little broader than in our specimens. The species is very near //. 

 crispatum, but the fronds are much more crisped, and the involucres are 

 orbicular, not ovate. In some specimens, however, there is an approach to 

 the ovate form. Stipes 2 — 4 inches. Fronds 3—4 inches. 



61. W.myriocarpum, Hook.; pendent flaccid, fronds elon- 

 gato-lanceolate compact tripinnatifid. primary divisions lan- 

 ceolate gradually smaller at the apex and base, the segments 

 short linear-oblong obtuse entire or retuse moderately spread- 

 ing, involucres very numerous on short lateral contracted seg- 

 ments broadly orbicular sessile 2-valved to the very base, the 

 valves convex entire, rachis slightly winged above. (Tab. 

 XXXVII. D.) 



Hab. Colombia, Harticeg, n. 1530. — Stipes 2 — 3 inches long ; frond a 

 span long, \\ — 2 inches broad where widest, regularly and closely tripin- 

 natifid, very flaccid, rich brown when dry, the fructifications very copious, 

 prominent on the upper side of the fronds, perhaps in consequence of their 

 pendent position. The graceful form and copious fructifications will rea- 

 dily distinguish this species. 



62. H. poli/antJios, Sw.; erect or drooping ovate or oblong 

 tripinnatifid, the segments short entire generally spreading 

 sometimes a little waved and ilexuose, involucres terminal 

 ovate or nearly orbicular free or the base slightly sunk deeply 

 2-valved, the valves convex entire or somewhat erose, stipes 

 terete naked or moderately winged above. — a. fructifications 

 mostly terminal on elongated subpalmated segments, involu-
