portions of the frond, and become singularly rounded and almost 
reniform. ‘The outline of many specimens of this variety, which 
T have only seen in the Herbarium of Mr. Pollexfen, to whom I 
am indebted for the specimen figured, is very similar to that of 
Kalymenia reniformis. Like var. y, its substance is thicker, and 
colour generally more full than in either of the preceding states of 
the species. 
Var. ¢ is like a combination of vars. a and §; the lobes of the 
frond being obovate as in the latter, but frmged with dichotomous 
lobes as in the former. Its claim to rank as a distinct variety 
rests on the narrowness and minute division of these marginal 
lobes. I regret that there was not room to introduce a figure of 
this variety into our plate.
