Ilab. Luzon, Curninff,n. 151 (tliis niinibcr is referred to l)y J. Sm. as La.i/rea 

 spectaf/ilis, in Hook. Bot. Joiirn. iii. p. 3!)9), and Snma?; w. 321 {Stenosemia aurita, 

 J. Sm. 1. c. p. 395). — This is a remarkable plant, and is subdimor])bous, that is, 

 the fertile fronds or pinna; are more contracted than the sterile ones. It corre- 

 sponds in its venation with § Pleocnemia in the Aspidium group. As in some 

 other GrammitidecB, tiie sori vary from oblong to subglobose. 



52. G. (Dictyogramme) Japonica, Desv. ; caudex creeping, 

 stipites a span to a foot long stramineous-brown very glossy, 

 fronds 1^-2 feet and more long 1 foot wide broad-ovate acu- 

 minate membranaceous pinnated subbipinnate below, pinnre 

 all petiolate subopposite 6-10 inches long 1-2 inches broad 

 from an obliquely cuneated base oblong subfalcate finely acu- 

 minate entire or serrated, veins copious approximate erecto- 

 patent anastomosing so as to form rather large costal areoles, 

 others forked partially anastomosing into narrow elongated 

 areoles the rest free towards the margin, sori copious often 

 on all the veins and uninterrupted (so as to have the sori of 

 Hemionitis next the costa, and of Gymnogramme towards the 

 margin). — Desv. Journ. Bot. \\\.p. 26. Kze. in Schk. Fil. Suppl.

Hab. Japan, Thunherg, Goriiig ; Yokaharaa, Oldham, n. 110. Island of For- 

 mosa, Swinhoe (pinnae very broad). — This bears tbf same relation to G. Javanica 

 that our G.podophylla does to G.pedafa. The only difference is in the venation, 

 and it is not a little remarkable that G. Javanica is also found to be a native of 

 Japan, viz. of Simoda and Hakodadi. 



53. G. (Dictyogramme) pinnata, Hook. ; caudex creeping 

 at the apex clothed with black setaceous hairs, stipites sub- 

 aggregated a span and more long glossy brown as well as the 

 rachis, fronds coriaceous a span to a foot and more long 

 nearly as much wide suboval glabrous subnitent pinnate, 

 pinucc 5-17 petiolate 5-10 inches long ^-1 inch and more 

 wide lanceolate or linear-lanceolate costatc, veins uniformly 

 anastomosing so as to form copious narrow-oblong oblique 

 areoles, veins soriferous, sori narrow linear and considerably 

 elongated subanastomosing (as are the veins) or short oblong 

 and very irregularly scattered. — Syngramme pinnata, /. Sm. in
