ovate, costa prominent on both sides, veins quite sunk and 

 obscure, sori copious very large prominent subrotund or sub- 

 oval forming a series on each side the costule of the segments 

 (often extending to the main costa) or in the upper portion 

 of the frond on each side the main costule to the apex. — Kl.

Hab. Columbia, Moritz, Burschel. Venezuela, Fendler, n. 251. — A very fine 

 species, very variable in size and in the length of the segnaents ; one of my spe- 

 cimens is forked at the apex of the terminal segments. 



362. P. (Phymatodes) oxijIobum,V\[dl\.; caudex creeping 

 stout paleaceous with dense subulato-falcate ferruginous 

 scales, stipites 2-5 inches long, fronds coriaceous or coriaceo- 

 membranaceous 6-12 inches and more long deltoideo-ovate 

 acuminate deeply pinnatifid to within ^ an inch of the rachis 

 with .'i-ll segments wliich are ^-G inches long ^-1 inch 

 wide very patent from a broad base oblongo-lanceolate very 

 finely acuminated entire thickened at the margin, the lowest 

 ones cuneato-decurrent, terminal segment often the longest 

 and most narrowly acuminated, venation conspicuous, cos- 

 tules often prominent beneath distant united by transverse 

 veins forming 3-4 series of primary areoles which are filled 

 up by lesser ones including free veinlets, sori large not sunk 

 arranged in a single series nearer the costa than the margin.

 ghcrries, Beddomp, n. 99 (margins of the segments sinuato-sublobate). — The 

 slightly attenuated and cuneated base of the frond, the thickened margin scarcely 

 at all serrated, and the sharply acuminated segments, are characteristic of this 

 species. 



363. P. (Phymatodes) incurvatum, Bl. ; caudex creeping 

 paleaceous, stipites scattered a span to a foot long of the ste- 

 rile frond, 2 feet of the fertile glossy-brown, fronds firm-coria- 

 ceous glossy dimorphous ; s/f'y-i/e ones 6-10 inches long 8 inches 

 to 1 foot wide hastato-tripartite rarely pinnatifid with 4-6 

 lateral lobes, lobes ovato-acuminate entire horizontal terminal 

 one very large all thickened at the margin, costules distinct 

 but immersed, venation internal and very indistinct; fertile 

 fronds very long stipitate 10 inches to a foot long nearly 

 as much wide very broad ovate deeply pinnatifid nearly to 

 the rachis, below subjiinnatc, segments 5-15 4-8 inches long
