 Madagascar, Boivin (pinnae smaller, and segments narrower). — Perhaps too 

 near the plant I have considered Aspl. arl/oresce7is, and evidently a widely-dis- 

 tributed species over India and the Malay Islands, and probably of the Pacific 

 Islands. 



283. A. (Eudiplazium) asperum, Mett. ; " fronds ample 

 bipinnate membranaceous glabrous, inferior pinnules shortly 

 petiolate lanceolate acuminate subcuneato-truncate at the 

 base pinnatifid, segments subfalcate oblong serrulate at the 

 apex, sori crowded minute (but distinct), rachis and stipes 

 asperous." — Diplazium, Bl. En. Fil. Jav. p. 195. Asplenium, 

 Mett en. Asplen. p. 190. 



Hab. Java, Blume, in Herb. Nostr., Thos. Lobb. — The author observes of this 

 species, " Priori {Aspl. pohjpodioides) valde affine, sed distinctum laciniis obtusis 

 et soris baud confluentibus, stipite aspero." I perceive, however, no difference, 

 save in the asperous and, indeed, almost prickly stipes and rachis, especially at 

 the back ; but in several of my specimens, which I consider true poli/podioidcs, 

 the rachis is occasionally asperous, and it would be better, perhaps, to consider 

 this a variety of that species. 



284. A. (Eudiplazium) dilatatum. Hook.; caudex?, stipes 

 stout 2 feet and more long below paleaceous with lanceolate 

 acuminate scales, frond ample membranaceous or coriaceo- 

 membranaceous tripinnate pinnatifid at the apex, primary 

 pinnse remote more or less sometimes long petiolate often 

 1-2 feet long once or twice pinnate pinnatifid at their apices, 

 pinnules extremely variable in size and outline and even 6 

 inches long horizontally from \ an inch to 1 or 1.? inch wide 

 sessile or petiolate from a usually truncated or cuneato-trun- 

 cate broad base oblong acuminate often finely so varying in 

 the margins even on the same pinna from entire to serrated 

 pinnatifid in various degrees sometimes to the costa and near 

 the base often pinnated, segments oblong or ovate acute or 

 obtuse frequently subfalcate entire or serrate, veins fascicled 

 in the entire or nearly entire becoming pinnated in the lobes, 

 veinlets simple or forked free rarely uniting, sori near the 

 costa narrow-linear not extending to the margin those on the 

 lower veinlets often diplazioid. — D. dilatatum, BL En. PI. p.
