same as his). Similar as the fronds of the two may be in structure, the stipites 

 in Eaton's plant are dark brown and tubercled, and the scales are dark chestnut, 

 very large, and lanceolate, long-acutninate. The most distinctive of this species is 

 the beautiful dense and longstupose silky clothing of the base of the stipes.* 



208. P. (Phegopteris) Jionestum, Kze. ; "frond lanceolate 

 pinnato-pinnatifid, pinnatifid at the apex, pinnee lanceolate 

 subfalcate acuminate shortly petiolate, lowest ones remote, 

 segments oblongo-falcate obtuse subrepand and ciliated at 

 the margin, stipes rachis and costse patenti-paleaceous be- 

 neath, sori uniseriate near the margin." Kze. in Linncea, ix.

Hab. Pampayaco, Peru, Poeppig, in Herb. nostr.,from Kze. — A rather obscure 

 plant. My only specimen of this is an original one from Kunze. It has Tcry 

 much the structure of P. spectabile, and still more perhaps with our Ful. Sloanei, 

 but I do not know if it has the very villous silky scales of the latter species. 

 The " venae inferiores repetito-furcatae " of Jlettenius do not accord with our 

 plant from Kunze, so that perhaps Mettenius had a different species in view. It 

 is recorded only as a Peruvian plant. 



209. P. (Phegopteris) dilatatum, Liebm. ; "stipes \\ foot 

 long, frond herbaceous ample 3-4 feet long broad-lanceolate 

 supradecompound quadripinnato-pinnatifid, primary pinnas 

 alternate remote petiolate, secondary alternate petiolate lan- 

 ceolate acuminate acute, tertiary ones alternate short-petio-

* I take the opportunity of here introducing the Aspidium (Lastrea) amplum 

 of Eaton, which should have been given immediately after our Nephrodium (Las- 

 trea) catopterurn, p. 137 of this volume. 



130 bis. Nephrodium (Lastrea) amplum, Hook.; caudex .', stipes IJ foot long 

 tawny-brown thick as a duck's quill obscurely tubercled and bearing sparse subu- 

 late small patent scales (which are continued on the rachises), the base densely 

 clothed with long (1-1 5 inch) dark-brown glossy lanceolate long-acuminated 

 scales, frond 3 feet and probably more long deltoitl-ovate suhmembranaceous 

 laxly tripinnate, primary pinnaj distant, lowest ones a foot long and bipinnate 

 broad-oblong, secondary ones 2-3 inches long sessile deeply nearly to the rachis 

 pinnatifid, segments and the ultimate pinnas or pinnules of the lower primary 

 pinnae oblong acute entire or more or less deeply pinnatifid from i-1 inch long, 

 veinlets simple subpellucid one to each lobe or lobule, sori rather small while 

 young evidently furnished with a small cordate slightly hairy or ciliated mem- 

 branaceous involucre. — Aspidium amplum, 3Ietten. Aspid. p. 74 {an Polyp, am-

Hab. Caripe, Venezuela (if the plant of Willdenow), Cuba, C. Wri(/ht,n. 1055. 

 Dominica, Dr. Imray, n. 56 (as far as can be judged by the frond). — I derive 

 the above character from Mr. M^right's Cuban specimen. I dare not introduce 

 the several synonyms referred to by Mettenius, which may or may not belong to 

 the same plant. The scales of the base of the stipes here are quite diflrerentfrom 

 those of our Polyp. ? Sloanei.
