CHARACTERS OF TRIBES AND GENERA. 187 



rigid, erect, covered with clavate glands, lacinae small 

 oblong spathulate, each furnished with a clavate venule, 

 which is sporangiferous on the apex. Sori round, solitary 

 on each lacinge. 



Type. AdenopJiorus tripinnatifidus, Gaud. 



Illust. Hook, and Grev., t. 174, 175, 176 (sub. Adeno- 

 phorus), Fee Gen. Fil., t. 10, A, fig. 1. 



OBS. Gaudichaud, in Freycinet's Voyage, was the first 

 to describe this genus, the speciality being the peculiar 

 rigid habit and glandulose nature of the fronds. But 

 owing to the sori not differing in character from Polypo* 

 dium, as defined by early authors, has led it to be placed 

 by Sir W. Hooker, and other authors, under that genus ; 

 but I agree with Fee in retaining it as a distinct genus. 

 Three species are described ; but all being natives of the 

 Sandwich Islands, it is therefore probable that they may 

 only be different states of one species. 



Sp. A. hymenophylloides (Kaulf.) ; A. tamarisci (Kaulj.) ;

Vernation sarmentose, short. Fronds fasciculate, linear, 

 sub-entire, sinuose repand, pendulous, 6 inches to 1J feet 

 long, 1 inch wide, villose, stipes slender, cylindrical. Veins 

 pinnate, forked, and arcuate, venules unequally anasto-
