 intricate-cespitose, yellowish green, facies of B. velutinum : stems creep- 

 ing, radiculose, sparingly branching, branches procumbent: leaves sub-

 sharply serrate all around; borders plane or partly revolute; costa vanish- 

 ing above middle, sometimes forked and shorter; cells rather loose, pellu- 

 cid, rhomboideal linear, alar quadrate sub-obscure; perichfetial bracts lanc- 

 eolate, long acuminate-subulate, acumen serrate: seta smooth, reddish;
