 lineatum). A. plumosum, Bory, in JVilld. iii. p. 323 ? [which

 michael. — This Fern varies like the preceding, A. longissimum, in size, and the 

 form and texture of the pinna} : and in a few instances I find it difficult (unless 

 the black scaly hairs of the caudex and stipes are present, and these are too apt to 

 be deciduous, except in the caudex, which is seldom present on our herbarium spe- 

 cimens) to distinguish the present species from that. Here, however, I have never 

 seen the upper portion of the frond extended into a proliferous apex, and though 

 in A. longissimum the base of the pinnae is generally auricled on both sides, yet in 

 all my numerous specimens of A. hirtum there is nevermore than one (superior) 

 auricle, and that is sometimes obsolete. Thus, as I believe, the plant becomes 

 the A. plumosum of Bory, as it certainly is the A. Ilelisinbergii of Sicber. There 

 is consequently a choice of names. I venture to reject that of Lamarck (pellu- 

 cidum), seeing not only that the name is singularly inappropriate, but the author 

 especially describes the pinnaj as " minces, transparentes," and he refers to the 

 figure of a West Indian plant of Plumier as the same as his, but with which few 

 who know our plant would institute any comparison. The name A. hirlum 

 appears unobjectioriable. Aspl. stenopteris and acutiusculum, Bl., seem to me 

 sufficiently to accord with the present species. 



115. A. (Euasplenium) setosum, Pr. ; "fronds elongato- 

 lanceolate pinnated, pinnae alternate petiolate oblongo-lan- 

 ceolate acute serrated with setaceous teeth between the ser- 

 ratures, superior base truncate and auriculate, inferior base 

 cuneate, veins bifid, rachis setoso-paleaceous winged above 

 prolonged at the extremity and radicant." Pi'esl, Reliq.

Hab. Luzon, Haenke. — Unknown apparently except to Ilajnke and to Presl, 

 who says, " Affine videtur v-/.7;/?<woso, Bory :" and adds, " sori desunt;" yet in 

 his Tent. Pterid. p. 113, he calls it Diplazium setosum. Aspl. setosum, Desv. 

 Berl. Mag. v. p. 322, from Madagascar, is no doubt something very different from 

 this, and said to be allied to A. ebeueum.
