haustible source of botanical treasures.. My work on Exotic 
Mosses hears testimony to the riches of Nepal in that depart- 
ment; whilst the present one is destined to include many of 
the Phznogamous Plants and Ferns which I have thence re- 
ceived. Among the latter, splendid as many of them are, few 
will be found to exceed the present in delicacy ; and none can, 
as a species, be more distinct. It belongs to a division of the 
genus (frondibus simplicibus), in which only three individuals 
had been hitherto included, all of them distinguished also by 
their articulated or jointed fronds. This last circumstance. is 
wanting in Aspidium Wallichii, besides which it has the clus- 
ters of fructification catenulated, and running down on each side 
of the midrib,-—characters which might perhaps authorise its 
being constituted a new genus. The term “ scattered sori,” 
(or clusters of fructification), is hardly applicable to the present 
species; that expression, as constituting part of the generic dis- 
tinction, having been intended to be placed in opposition to 
those sori which were marginal, or to those covering an entire 
portion of the frond.
