This is treated as a form of J. leucomelas, Royle, in Hook. f.

to differ in wanting the leafy prolongation to the lowest bract 
which is so characteristic of J. leucomelas, Royle.

Only one specimen of this is at present known, which is re- 
ferred to J. triglumis, Linn., by Buchenau in Engl. Bot. Jahrb. 
xii. (1890) p. 388; but it differs from that species in having a 
short sheathing leaf near the top of the stem, and when better 
known will probably prove distinct.
