Found on the Continent and in North America. 



Obs. — I am uncertain whether to regard this as the male form 

 of B. tricrenafa, or as a distinct species, or as merely a variety ; 

 the numerous specimens I have been enabled to examine are either 

 sterile or male plants only. 



It is distinguished from B. tricrenafa by its smaller size, more 

 slender stems, which are usually, but not always, dichotomously 

 innovantly branched, leaves soon falling away, proportionately 

 shorter (except in var. faccida); cells rounder, with large and 

 distinct trigones, stipules patulous, usually sub-entire. In var. 

 faccida the leaves are plane, narrower, often entire and apiculate. 



From B. Pearsoni (Steph.) it differs in its smaller size, more 

 delicate habit, brownish-green or olive-brown colour, dichotomous 

 ramification, antical base of leaf not large or overlapping, cells 

 with large trigones and broader stipules.
