TAB. XIII. 
Asplenium (Athyrium?) grammitoides, Hook. 
Humile, fronde herbacea firma parce setulosa oblongo-lance- 
olata longe acuminata pinnata superne pinnatifida, pinnis 
lanceolatis subfalcatis obtusis basi superiore auriculatis om- 
nibus lobato-vel dentato-pinnatifidis, stipite brevi paleaceo, 
paleis setaceis patentibus crispatis, soris satis magnis, invo- 
lucris oblongis planiusculis ciliatis, inferioribus seepe dipla- 
zoideis. 
Diplazium grammitoides, Presl, Epimel. Bot. p. 84. 
Hab. Luzon, Cuming , n. 56. Java, Thos. Loibb , n. 258. 
Mr. J. Smith in his Enumeratio Filicum, after the names 
of ten species of Diplazium , observes that “ Mr. Cuming’s n. 56 
is probably one of them in a young state.” Our plants, 
however, from that collector, have every appearance of being 
perfect, and this view is confirmed by copious specimens, iden- 
tical with these, having been found in Java, by Mr. Thomas 
Lobb, and which are here figured. The late Dr. Presl enter- 
tained the same opinion, and described our plant in the work 
above quoted, as a new species, Diplazium grammitoides . The 
specific name I willingly adopt, though I doubt of the pro- 
priety of referring it to the Genus Diplazium , unless Diplazi- 
um were to receive every Asplenium which had a double 
involucre ever so sparingly mingled with the single ones. 
Here a displaziod involucre is only found towards the base of 
the pinna, and where a lobe or pinnule may be considered to 
be combined with the pinna, each half opening towards its 
own rachis or costa. With more propriety it might be placed 
in Athyrium , as Fee has referred the Diplazium brevisorum of 
J. Smith, the species immediately after which Smith notices 
this, and from its affinity with Athyrium Hohenackerianum of 
Kunze(Schk. Fil. Suppl. tab. 126); — but which, nevertheless, 
M. Fee places in Asplenium. So different are the views of 
Botanists in regard to the Genera of Ferns: Botanists, too, 
alike anxious to fix them upon a firm and solid basis.
