240 POLYPODIUM, § PHEGOPTERIS. 



analogous to those just described but of a darker colour and 

 these are continued up the rachis, fronds 2-2 h feet long 

 nearly 1 foot wide subcoriaceous opaque bro\A-nish-green 

 when dry copiously dotted with crovA^ded pellucid yellowish 

 points, pinnated pinnatifid only at the very extremity by the 

 union of 2-3 of the upper pinnee, pinnae 3-5 inches long 

 1-1 J inch broad petiolate from a broadish subunequally cu- 

 neate and truncated base oblong rather suddenly acuminated 

 pinnatifid ^ or j of the way doAvn to the costa, segments 

 l)road short in comparison to the breadth of the pinnae 

 very obtuse at the base but the acute point turning upwards, 

 veins pinnated distant, the branchlets or veinlets 10-12 

 elongated erecto-patent each bearing a sorus below the mid- 

 dle thus forming a series on each side the primary vein, 

 veinlets all free but the apices approach each other near the 

 sinus without uniting, costse and costules especially beneath 

 subhispido-paleaceous. — Raddi, Fil. Bras. p. 25. t. 37 {not

Hab. Brazil, Raddi. San Gabriel, Spruce, n. 2100, and Tarapofa, Eastern 

 Peru, Spruce, n. 4G57 and 4742 (more deeply pinnatifid). British Guiana, R. 

 Schombiirgk, n. 1128 (P. reMgei^s, Kl. in Ilerl/.tios/r.). — I have no authenticated 

 specimen of P. Tijuccanum of Raddi; but Raddi's figure so well represents the 

 specimens I have referred to that species, that I can hardly have a doubt of their 

 identity. As in P. flavo-punctatum, pellucid yellow dots in the fronds (only 

 seen when held between the eye and the light) are very conspicuous ; but here, 

 notwithstanding the thicker substance and generally opacity of the frond, the 

 pellucid dots are much more numerous and better defined, exhibiting a more re- 

 ticulated appearance. The pinnae are, too, much broader, and the pinnatifid 

 character is confined to the apex. — What is P. alloeoptej-uni, Kze. and Schlecht. in 

 Linnaea, xxv. p. 50 .', of which it is said, " Non nisi cum P. Tejuccano, Raddi, ali- 

 quam ostendit similitudinem," etc.

 ascending, stipites tufted 1-H foot long tawny-brown scale- 

 less, fronds 12-14 inches and more long 6-8 inches broad 

 subcoriaceo - membranaceous pellucido - punctate glabrous 

 ovato-lanceolate acuminate pinnate, pinnee distant all pe- 

 tiolate horizontal few (about twenty) 3-4 inches long | to 

 scarcely 1 inch broad from an obliquely cuneated base trun- 

 cated and auricled above subexcised beneath oblong acumi- 

 nate lobato-pinnatifid at the margin with short ovate or 

 rounded lobes and acute sinuses, the apex serrated, terminal 

 pinnae broad-ovate acuminate irregularly but not deeply pin- 

 natifid, veins subflexuose pinnate with about 6-8 simple 

 veinlets each bearing a dorsal sorus near the middle, rachis 

 slender.
