190 DRYMOGLOSSUM. 



thulate, stipites of both fronds elongated and very slender). — My copious suites 

 of specimens exhibit such a variety of forms and size, that, different as the ex- 

 tremes may be, there is ample evidence, to my mind, of their being but one 

 species. 



Of the species of Drymoglossum in Moore's Index Fil., I would observe that 

 D. ahhreviatum, with its uniform fronds, D. Cunning Jiami, Jloore, D. ellipti- 

 cum, Moore, are too imperfectly known to enable me to form any opinion about 

 them; D. acrostichoides, Moore {Vittaria, Hook, and Grev.), is assuredly, as 

 Mr. Moore has since acknowledged, an imperfectly soriferous state of Acrosti- 

 chum conforme, and D. lanceolatum is a Tctnitis of this work. 



2. D. piloseUoides, Pr. ; caudex long filiform wiry clothed 

 with appressed peltate laciniated scales, stipites 2-10 lines 

 long (in the fertile frond) distinct jointed and deciduous near 

 the base, fronds simple of two kinds; sterile ones ^ an inch 

 to 2 inches long orbicular subcordate obovate or elliptical 

 thick and fleshy coriaceous when dry, entire indistinctly 

 costate, veins anastomosing, the areoles including free simple 

 or branched and divaricating veinlets; fertile fronds l|-3 

 inches long linear-oblong obtuse tapering at the base, sori 

 linear continuous just within the margin at first narrow 

 eventually spreading so as to cover the whole back of the 

 frond leaving a furrow between, capsules mixed with pel- 

 tate pedicellated scales. — Pr. Tent. Fterid. p. 227. t' 10.

Hab. Tropical East India, most abundant on the mossy trunks of trees : Malay 

 Islands, Malacca, and the continent of British India westward to Nilghiri {Bed-
