 broad ; lower sheaths green or purple. Panicle 1-2 in., strict, branches stout densely

The most delicate little species known to me, resembling Avra caryophyllea in size 

 and slenderness, but growing in dense tufts. Leaves about 1 in., convolute, 

 flexuous ; ligule short, oblong. Fanicle about 1 in. long and broad, branches gemi- 

 nate, quite smooth. SpiTcelets remote, purple, keels of gl. I and II scabrid, pedicels 

 rather long. Chain oblong. — A single specimen of a Sikkim Agrostis in Herb. 

 Calcutta (n. 663 in part) without further habitat, resembles this in the small 

 stature and panicle, but has a much stouter stem, and flat leaves about xg-^^ 

 in. gl. I and II are more obtuse. More specimens of both are much wanted.
