ABPLENIUM, § EUDIPLAZIUM. 24? 



inferior pinnae quite free forming a distinct cuneato-obovate 

 sessile pinnule with two series of sori, fronds more firm and 

 subcoriaceous. — Var. 7. ohtusum ; characters of the preceding 

 var. but pinnae shorter and obtuse. — Aspl. semihastatum,

 Jamaica, M'Faclyen, and at " Colilspring Gap," Purdie. — Var. 7. obtumm. Jamaica, 

 Herb. Nostr. — The ordinary form of tliis, as described by authors, and seen in Mo- 

 ritz's Columbian specimens, quoted i)y Mettenius, so closely resembles our i)reviou8 

 species, A. striatum, that, except in the narrower fronds, more cuneate base of 

 the pinnae, their more prominent auricle and scarcely pinnatifid — sometimes only 

 serrated — margins, I do not see how it is to be distinguished. But some of my 

 specimens, especially from Jamaica, have from 1 to 12-13 of the lower pinnae 

 with a free auricle or distinct pinnule, yet the passage to the ordinary auricle 

 may among these be traced. The caudex described by Willdenow is perhaps by 

 mistake given as arborescent, but in A. striatum, from a portion of one preserved 

 by Mr. C. Wright, the caudex is erect and stout, though far from " octopedalis, 

 diametro tripollicari." Under the var. obtusum of his Aspl. semihastatum, Met- 

 tenius says, "Transitus ad A. auriculatum non vidi;" but my copious specimens 

 lead me to entertain a ditlereut opinion. 



266. A. (Eudiplazium) cultratum, Metten. (not Gaud.) ; 

 caudex stout erect crowned with black subulate scales, sti- 

 pites 4-6 inches long with black scales at the base, " frond 

 coriaceous glabrous oblong pinnate, pinnae ovate-oblong fal- 

 cate acute obtusely serrate, the superior base truncate and 

 ^uricled inferior rotundato-obtuse, lowest ones petiolate, mid- 

 dle ones sessile, superior ones adnate with their inferior base, 

 those at the extremity coadunate into a pinnatifid apex, stipes 

 above rachis and petioles clothed with short conico-cylin- 

 drical pellucid horizontal down, veins internal." Diplazium,

Hab. Luzon, Cuming, n. 199. Lower pinnae rather long-petiolated, 2 inches 

 long, f of an inch broad. — This is one of several species of Mr. Cuming, with 

 different numbers, which Mr. J. Smith has included under the name of Diplaz. 

 ex'tensum. He had this, n. 199, probably, more especially in view when he says 

 of three of the numbers which he brings under that species, " not unlike Dipla- 

 zium grandifolium of the West Indies."
