 there is no possibility of confounding it with any other, save G. (Dictyogramme) 

 Japonica, from which however the different venation will at once distinguish it, 

 anastomosing in the latter, always free in G. Javanica. 



§ 2. Ceropteris. — Veins free, simple or forked ; fronds clothed beneath ivith a 

 white or yellow pulverulent substance. — Gen. Ceropteris, Link and Fee. Tris- 

 meria, Fee. 



43. G. (Ceropteris) flavens, Klfs. ; caudex very short erect 

 ferrugineo-paleaceous, stipites tufted 8-10 inches long slen- 

 der ebeneous-purple glossj'^ fragile, rachis and its branches 

 quite capillary, fronds coriaceo-membranaceous 3-6-8 inches 

 long triangular-ovate dark-green and naked above bright and 

 copiously yellow-puverulent beneath tripinnate, primary and 

 secondary pinnae long-petioled broad-ovate, pinnules 2-4 

 lines long articulated upon the rachis and upon the petiolule 

 elliptico-rotundate entire easily deciduous, veins twice forked 

 bearing linear sori upon the branches each of few and lax 

 capsules more or less confluent. — Klfs. En. Fil. p. 77- Hook.

 Humboldt and Bonpland; Loxa, Seemann. — This elegant and well-marked Fern has 

 been placed in Acrostichum, Cincinalis, and Nothochlcena ; but surely Kaulfuss and 

 Kunze are correct in referring it to Gymnogramme. See some remarks under our 

 Nothochlcena nivea, at p. 112 of this volume.

 inches long subcoriaceous pedately triangular or subpentan- 

 gular in outline dark-green above yellow or deep-orange farina- 

 ceous or rarely white beneath pinnate, pinnse sessile generally 

 opposite3-4 pairs of the ultimate ones confluent into a pinnati- 

 fid apex, lowest pair half-triangular (the lowest inferior pinnse 

 the longest) and again subpinnate, pinnse and segments oblong 

 obtuse more or less obtusely lobato-pinnatifid, sori oblong
