(724.) B. harpidioides, C. M. & Kindb. (n. sp.) 



Tufts compact, soft, radiculose below, whitish or bright green, not 

 shining. Stems intricate, irregularly branching or pinnate. Leaves 

 patent, somewhat loosely disposed, decurrent, more or less arcuate 

 (principally the upper), not auricled, plicate, nearly flat, ovate and 

 subulate-acuminate ; borders faintly denticulate and recurved often all 

 around ; cells distinctly chlorophyllose, the alar large, subquadrate, 

 the other lanceolate. Dioecious. Capsules not found.

 very peculiar in the arcuate leaves as in the section Harpidium of the 

 genus Hypnum.
