Radix caespitosa, e fibris numerosissimis, gracilibus, valde ramosis, fuscis. 



Stipites, plurimi ex eadem radice, tres ad quatuor uncias longi, erecti, flexuosi, hinc canaliculati, atro 



nitidi, pilis membranaceis fuscis patentibus obsiti ; fertiles reliquis duplo triplove longiores. 

 Frondes tres uncias longae, fusco-virides, subcoriaceae, obscure reticulatae, costatae, supra glabrae, subtus margine 



paleaceo-hirsutae ; steriles oblongo-cordatae, obtusae ; fertiles magis triangulares, sinu lato, profundo. 

 Capsulce numerosissimae in venas reticulatas, areolis oblongis, demum confluentes. 

 Semina minutissima, fusca.

Desvaux first separated from the Hemionitides of Swartz and Willdenow the genus Gymnogramma 

 (Tab. xxv.), and Kaulfuss, more recently, that of Antrophyum (see Tab. xlvi.) ; thus reducing Hemio- 



■ 



nitis to the single species H. palmata, which certainly had little or no natural affinity with its 

 former associates. With that, however, our present plant entirely agrees, both in general habit and 

 in essential characters. It was discovered many years ago by Dr. Roxburgh ; and, in his unpub- 

 lished Catalogue, is marked generally as an inhabitant of Bengal : and upon the ticket written by 



Dr. Wallich, which accompanied the specimens kindly communicated by the Honourable the Di- 

 rectors of the East India Company, it is described as flourishing in the rainy season in the neigh- 

 bourhood of Calcutta. We find beautiful specimens of the same plant in a valuable botanical col- 

 lection presented to us by the late excellent Dr. Shuter. These specimens, however, have the fronds 

 more acute at the angles than is the case in our plant.
