very different in the short teeth-hke lobes of the frond, and in the oval or oblong 

 sori, which are large and so approximate as to cover and conceal the whole disk 

 of the frond. 



38. P. (Eupolypodium) trichomanoides, Sw. ; caudex short 

 erect paleaceous above densely rooting with wiry fibres, 

 stipites short i-1 inch long densely tufted patenti-villous 

 with long fulvous hairs, fronds 3-4 inches to a span long 2-4 

 lines wide rigid-membranaceous linear attenuated at both 

 extremities deeply nearly to the costa pinnatifid or almost 

 pinnate (quite so at the very base), lobes horizontally patent 

 from a Ijroad base ovate or oblong entire subconcave beneath 

 subdeciduously ciliated with long fulvous or blackish patent 

 hairs, veins solitary in each lobe and forked, upper branch bear- 

 ing a single sorus near the costa. — Sw. Syn. Fil. p. 184.

Hal). Tropical America, abundant on the mainland, from Brazil and Guiana to 

 the Pacific, and in the islands. East Indies: Malacca, Cuming, n. 380; Lachen, 

 Sikkim-Himalaya, Hooker, fil. — /3. Island of Ascension, summit of Green Moun- 

 tain, alt. 2800 feet. Hooker, fil. — This is doubtless a very variable Fern in size 

 and texture, and I am not sure that the lobes are always monosorous ; nor am I 

 satisfied that the following species, P. triincicola, is really distinct from it. 



39. P. (Eupolypodium) triincicola, Kl. ; " fronds ceespi- 

 tose linear rigid membranaceous sinuato-pinnatifid spa- 

 ringly and on both sides fuscescenti-pilose, the apex short 

 towards the base much attenuated, segments short oblong 

 obtuse entire approximate erecto-patent alternate monosorous, 

 sori large deep-brown approximate to the costa." — Kl. in 

 Linn(sa, xx. p. 374. Metten. Polyp, p. 40.

 summit of the Blue Mountains, Jamaica, Pnrdie (passing into P. trichomanoides). 

 Juan Fernandez, Douglas (scarcely differing from P. trichomanoides). — Some of 

 the Ecuador specimens are very fine, large, and bear long rich brown-coloured 

 hairs very copiously, not only on the margins of the fronds, but on the superficies 

 still I have numerous samples showing, as it appears to me, a passage from the 

 one species to the other.

 derately stout subrepent fulvo-crinite copiously rooting, sti- 

 pites tufted 2-3 inches long slender filiform villous with long
