wo numbers gathered by Schultz are distinguished as species by Beeckeler, 
d the separation is apparently justified by the specimens in the Berlin herbarium, 
but those of the Kew herbarium differ much less from each other, and F. Mueller's 
Specimens are quite iniertiédinte in most respects. The length of the involucral 
bracts and the ani of the glumes upon which the distinctions are chiefly fo — 
are so variable, that I am unable to give tangible characters even for two dinde 
varieties.

I have followed Asa Gra ay in transferring this section from Scirpus (Isolepis) to 
Fimbristylis, of which it has entirely the habit, as the Ae bulb, though persistent
