opjiosite 11-10 suhorecto-patcnt 1-3 inches long h ati inch 

 wide from a broad decurrent base elon^ato-oljlong gradually 

 but sharply acuminate, the margin slightly thickened espe- 

 cially on the under side, terminal segment elongated, vena- 

 tion immersed very indistinct, no evident costules (according 

 to Mettenius's figure the veins form two or three series of 

 rather large areoles of which the second series from the costa is 

 fertile, each has one or more free veinlets), sori rather small in 

 a single series (chiefly in the superior half of the frond) nearer 

 the costa than the margin. — Kze.hi Mdten.p. 102. t. 2. f. 12,

Hab. Luzon, Cuminy, n. 124, Brackenridge. — Many of the pinnatifid species 

 of tlie Phy)nafo(les group need a clear view of the venation to distinguish some 

 of the most essential of the specific characters. This, which I believe is a suffi- 

 ciently good species, has the fronds very glaucous beneath, and a caudex coarsely 

 crinite with spreading, subulate, dark-brown, glossy setae. 



383. P. (Phymatodes) palmatum, Bl. ; caudex creeping 

 ferruginous with copious large glossy lanceolate long acumi- 

 nated scales, stipites a span to a foot and more long slen- 

 der, fronds 6-8 inches long subcoriaceo-membranaceous 

 glabrous broad-ovate acuminate cuneate attenuated at the 

 base deeply pinnatifid or not unfrequently decurrently pin- 

 nate or truly pinnate M'ith the always sessile or more or 

 less decurrent pinnte or segments 3-8-9 5-6 inches long al- 

 ternate with very obtuse sinuses terminal one the largest; 

 sterile ones 1-2 inches wide broad-lanceolate ; fertile ones 

 generally longer, all of them contracted near the base very 

 finely and subcordately acuminated entire, venation mani- 

 fest, costules evident veniform extending nearly to the mar- 

 gin united by transverse slender veins forming the primary 

 areoles, secondary ones irregular enclosing free veinlets, sori 

 compital in a single series nearer the costa than the mar- 

 gin.— iJ/. Fil. Jav. p. 150. /. 64 [not Pr.). Metten. Polyp,

 I'eru of the Phymatodes-i>tci\on well figured by Bluuie, at least as far as the fer- 

 tile plant is concerned. Our sterile specimens have much broader segments, and 

 are more contracted at the base. In both, the apices are remarkably finely acumi- 

 nated, so as to be caudato-cnspidate. The P. angustatum, Bl., I consider a very
