_ nized as Dicranum polycarpum (— Cynodonlium polycarpum 
Schp.); and this determination being apparently generally 
accepted, Did. Jenneri was allowed to lapse into oblivion; and 
__itis treated as a mere synonyÿym of Cyn. polycarpum by Limpricht, 
Roth, etc. The description and especially the excellent figures 
however leave no doubt that the plant described did not belong 
to C. polycarpum as now understood ; the leaves for example are 
described as smooth, not papillose (« haud papillosa »), and the 
figures of the cells and leaf apex are quite conclusive; —-this 
apart from the fact Dr. Stirton has compared an original speci- 
men of Howie’s and found it identical with the more recently 
described C. laxirele Grebe. d 2 
It follows therefore that if the plant be regarded as a distinct 
specific name must be retained, and will stand as follows :
