832 GRYPTOGAMIA ALG^. t| 



We doubt whether this be a diftinft fpecics from 

 the former. It differs however from it in the 

 following refpeds : The ftalks grow more in 

 cluftcrs, are more repeatedly branched, and ter- 

 minated in fhortcr forks or horns, and are gene- 

 rally more foliaceous. Their colour is com- 

 monly white, fpotted with green, but are fre- 

 quently alh-colour'd, and often fufcous, efpe- 

 cially the young plants, and the forks of the 

 old ones. The tubercles are rarely found. They 

 grow on the points of the forks, and are fmall, 

 round, and reddilh.

 So far as we can judge from our own fpecimens, 

 and thofe of Dillcnius at Oxford, we are inclin'd 

 to think that this is no other than a variety of 

 the preceding. The young plants in both are 

 exadlly fimilar, and agree precifely with the 

 figure of DjJkniuSi Hiji, mufs. t. 16.' /. 27. A.
