1 mm wide, divided to one-half or more of their length into four or five unequal

 of each segment opposite or whorled, the cilia long, few, simple or rarely 

 branched, the cells long, the cuticle striolate-papillose ; lamina four or five cells 

 high, the cells averaging 62 X 19 [).. Underleaves 1.0 mm long, 0.3 wide, divided 

 to one-fourth of their length into four (bisbifid) segments each with one to three 

 cilia as in the leaf. Branch leaves and underleaves similar to those of the stem, 

 smaller. Male inflorescence intercalary on a stem or branch, the bracts and 

 bracteoles in ten or more series, the bracts concave, divided into five or six seg-
