90 HYMENOPHYLLUM. 



10. H. hirtellnm, Sw. ; small hairy (especially on the 

 costa) and margin) with fulvous branched hairs, frond ovate 

 oblong slightly acuminate thin membranous but elastic tri- 

 pinnatilid, the segments narrow linear slightly attenuated ob- 

 tuse closely i)laced, involucres ovalo-orbicular slightly and 

 oblifpuly cuneate at the base ])artially sunk in the frond and 

 a little broader than the segments, the valves ciliated, stipes 

 very slightly winged above hairy to the base. (Tab. XXXI. 

 D.)—Sic. Sijn. I'd. p. 149. Wllld. Sp. PL v. 519. 



Hah. Jamaica, Swart::. Wet banks, Fox's pass, St. George's, Purdie. — 

 Allied to //. ciliatum; but I think quite distinct, in the smaller more com- 

 pact and generally ovate fronds, the slightly winged and hairy stipes, the 

 dirtVrcnlly shaped involucres and the striking elasticity of the frond, in 

 which latter respect it resembles the //. elasticiim of Mauritius. 



11.11. CJiiloense, Hook.; small tufted, frond lanceolate sub- 

 bipinnatifid with simple hairs or rarely branched at the base 

 on the margin and under surface, glabrous above, segments 

 broad linear obtuse, involucres axillary free ovate toothed 

 obovato-cuneate, valves semiorbicular deeply ciliated at the 

 margin slightly hispid at the base beneath, stipes not winged 

 glabrous. (Tab. XXXII. A.). 



Hah. Chiloe, Cuming, n. 8 and 12. Valdivia, on trunks of trees in woods, 

 Bridges, n. 797. — A small densely tufted species, with rigid costa, broad 

 segments, and the involucres always axillary. The hairs are rigid and ap- 

 pear seated on a minute dark tubercle. 



12. II. Orgnnense, Hook. ; frond tall ample ovato-acumi- 

 nate tripinnatifid, primary divisions broad-lanceolate acumi- 

 nated, the segments linear simple or bifid obtuse toothed and 

 as well as the costa obscurely ciliated, involucres at the api- 

 ces of the frond or of the lower primary divisions copious nar- 

 row ovate free 2-valved to the base the valves convex dentate 

 and obscurely ciliated, stipes not winged slightly hairy. (Tab. 

 XXXII. B.) 



Hah. Moist shady rocks, Organ mountains, Brazil, Gardner, n. 210. — 

 A highly beautiful and very distinct species. Stipes 6 — 8 inches long; frond 

 8—10 inches. 



13. II. vdhnluvi, Hook, et Grev. ; fronds oblong-ovale 

 acuminate tri])innatifid, segments broadly linear rather acute 

 simple or forked undulate slightly margined indistinctly cili- 

 ated, rachis and costa piloso-hispid, involucres copious upon 

 the upper segments ovate free convex ciliated or naked, stipes 

 not winged. — Hook, et Grev. Ic. Fil. <. 219. 



Hab. Columbia; trunks of trees, forests of Esmeraldas, at an elevation 

 of 3—4000 feet; and on the descent from Mollituro to Naransal, eleva- 

 tion of ()000 feet, Jamemn, Cnl. //«//.— Stipes 2 — 1 inches, black, destitute 

 of wing. Frond 4 — 7 inches long. Fructifications large, conspicuous, con-
