The male plant (heretofore undescribed) occurs in the Ovolau col- 

 lection. It is about the size of the fertile plant, and more compound 

 in its ramification. The branches and branchlets are attenuated into 

 long pendulous flagellse, clothed with minute appressed leaves; giving 

 to the whole plant a light, feathery aspect. Male buds few, stipitate, 

 situated in the axils of the stem-leaves; perigonial leaves 10-12 ; the 

 lower ovate, ecostate, muticous; the upper oblong, slightly margined, 

 erose-dentate above, suddenly produced into long, spreading points in 

 which the heavy excurrent costa is predominant; antheridia 18-20, 

 large, elongated, pedicelled ; paraphyses numerous, linear, acute, 20- 

 septate, longer than the antheridia.
