 Stipes 2 — 5 inches loiipf, stout, nifo-tomcnlose. Fromls amoii^f the largest 

 and most elegant of this beautiful genus, 1 — 1^ foot long. Finnic very 

 crowdeil, thin and membranaceous, undulato-crisped: fructifications some- 

 times so copious as to occupy every lobe and vein of the pinna;, and these 

 are large and almost C(iiially transparent with tlic I'rond.

Hab. Woods at Pillao, Peru, Ruiz ct Pavnn in Herb. Lambert. — I am 

 indebted to Mr. Fielding for a specimen of this curious Trichomancs, which 

 was derived, as well as his own specimens, and those in the Banksian her- 

 barium, from the museum of the late Mr. Lambert. The present has ma- 

 ny points in common with the preceding, yet is, I think, truly distinct. 

 The stipes is stout, 4 — 5 inches long, clotlied with dense, woolly, rusty to- 

 mcntum. The frond, apparently erect, 8 — 10 inches long, scarcely 2 inches 

 wide, and nearly of the same width throughout, peculiarly stiff and rigid, 

 ferruginous from copious rust-coloured hairs, which, on the under side, form 

 a dense covering of wool. The pinna; point upwards and forward, so as to 

 be subsecund, and they are so closely placed as to be imbricated, they are 

 sessile, rather deeply pinnatifid, with the segments ()1>long and obtuse, often 

 again divided, so that the pinna- may be said to be pinnatilid. The fruc- 

 tifications are confined to the uj)per portion of the frond, and arc there con- 

 spicuous by the copious long rece])tacles.

 setose glaucous, younger plants pinnatifido-digitate, pinna; 

 subalteniate cuneato-oblong ])innatifid, the segments cimei-

 winged, stipes terete glabrous." Bl. En. Fil. Jar. p. '2'2o. —
