Hub. Central America, Cumiiiff, n. 1169. — Presl and Lowe's fijjures well re- 

 present this plant and its conspicuous venation. In that particular, and in the 

 general shape of the frond, this and the preceding species have a great similarity, 

 but not in other particulars. 



289. P. (Craspedaria?) nuinmul avium, Metten.; caudex 

 slender long creeping branched setose with imbricated sul)u- 

 late scales, fronds sparse subcarnoso-coriaceous ghil)rous di- 

 morphous ; sterile stipitate ^-'^ of an inch long orbicular-ovate 

 very obtuse crenated at distant intervals with very narrow clefts 

 or sinuses the surface cellular with raised crystaUine dots 

 obscurely costate, costa channelled above, stipes j of an inch 

 long, veins sunk very obscure anastomosing " with areoles of 

 Doodia" (Metten.) ; fertile fronds 3 inches long very narrow- 

 linear subsinuated on extremely slender stipites nearly as 

 long as the fronds, costa slender prominent beneath, " veins 

 anastomosing and forming unequal elongated areoles in 2-3 

 series" (Metten.), sori in my specimen in two series close to 

 the costa. — Metten. Pohjp. p. \05. Marginaria, P/*. Gonio-

Hal). Luzon, Cuming, n. 121. — A very graceful and peculiar species, hut of 

 which the true nature of the venation is obscure : and hence, doul)tless, the dif- 

 ferences in the figures of Foe and Mettenius. Tlie crenatures of the frond are 

 remarkable, exhibiting fissures in the margin, with very broad teeth between them. 

 The surface also exhibits a great number of very minute crystalline points. The 

 species appears to have been found only by Cuming. 



290. P. (Craspedaria?) neg/ectum, Bl. ; "fronds minute 

 coriaceous margined remotely crenulate single-nerved (cos- 

 tate) veinless glabrous ; sterile ones obovato-rotundate; /ey*- 

 tile ones spathulate longer stipitate, sori solitary, caudex 

 creeping paleaceo-setaceous." — Bt. En. Fit. Jav. p. 121, Fit.

Ilab. Java, Blume. Luzon, il/p//eH.— The caudex and sterile fronds (1-1. V inch 

 high) of this plant very much resemble those of Pol. nummularium, but the fer- 

 tile troiids are shorter and broader. Presl. in bis last work on Ferns, consiflered 

 it worthy of constituting a new genus. There are other supposed species of this 

 {Craspedaria) group, under Craspedaria, Marginaria, Pleopellis.ctc, but fliey are 

 imperfectly described, and I can oiler little or no satisfactory opinion aliout tiicm.
