 Herb, nostr. — Stipes very variable in lengtli, when short, winged almost to 

 the base. Frond 2 — (> inches long, varying in diameter. Involucres 

 broader than the segments, rounded but cordate at the base and generally 

 oblique there, one lobe being larger than the other, a character not distinct- 

 ly represented in our Ic. Fil., nor even by Hcdwig, but which yet appears 

 to me very constant. 



7. H. Plumieri, Hook, ct Grev.; frond broadly lanceolate 

 l)i])innatifid, costa and margins with stellated ferruginous 

 hairs, primary divisions ovate acuminate pinnatitid half-way 

 down, the segments oblong forked or trifid, involucres subor- 

 bicular cuneate the base sunk, the valves free ciliated, sti])es 

 with a broad decurrent wing. Hook, et Grev. Ic. Fil. t. 123.

rial). Hispaniola, Plumier. Pichincha, Columbia, Jameson. — A robust 

 handsome plant, with compact broad primary divisions, less deeply cut than 

 most of the bipinnalilid species. Fructifications numerous, terminating ma- 

 ny of the segments and forming an interrupted line round the margin. To 

 this rather than to //. ciliatum (surely not to //. hirsutum, as VVilldenow 

 quotes it) I think Plumier's figure should be referred : — though it must 

 be confessed the two species are very nearly allied. 



8. H. irichophylluin, H. 13. K. ; " fronds bipinnate ferru- 

 gineo-hirsute, secondary pinnae dichotorao-pinnatifid, the 

 segments linear nearly entire, rachis hairy terete naked, sori 

 terminal, valves of the involucre semiorbicular hairy." H. B. 

 K. Nov. Geit. Am. i. p. 22. 



Hab. Mountains of Cumana, Humboldt and Bonpland. — Tlie authoi-s 

 speak of this as a very elegant sjiecics, nearly allied to H. ciliatum ; but 

 they observe " frondes pedales ? bipinnatae (aut plus compositae ?).'' It 

 might be inferred from the word " bipinnate,'' used by the authors, this plant 

 should be referred to another division ; but the temi is frequently employed 

 by them to express such species as I consider bipinnatiGd, that is, they meau 

 bipinnate with the rachis winged. 



9. H. Boryanum^ Willd. ; hairy especially beneath at the 

 margins with branched hairs, frond ovato-oblong scarcely 

 acuminated bi-tripinnatifid, the segments linear obtuse, invo- 

 lucres suborbicular cuneate at the base and there sunk in the 

 frond, the valves ciliated, stipes short winged above. (T-vb.

Hab. Mauritius and Bourbon, Bory, Bojer, Cannichael, Telfair, Wal- 

 lich. — Fronds small, seldom more than 3 — 4 inches long, very hairy be- 

 neath, much less so above, the primary segments close with blunt apices. 

 Nearly allied to II. ciliatum, but the involucres are very dilVereut, never 

 cordate at the base, but cuneate and partially sunk in the frond.
