what channelled, 1 to 4 inches long. Stem leaves 3 or 4, the upper- 
most one 1 to 3 inches long, by yV to ^ inch broad; sheaths quite smooth, 
the uppermost one less than twice as long as its leaf; ligule long, 
laciniate at the apex only. Panicle 1 to 5 inches long; panicle-branches 
very slender, the longest 1 to 2^ inches long. Spikelets inch long, 
exclusive of the awns. Glumes brownish-purple with a green midrib, 
rarely wholly pale green. Anthers oblong, purple, broader in pro- 
portion than those of A. setacea. Lower pale longer in proportion 
to the glumes, and with a much narrower truncate apex than that 
of A. setacea, and differing also in having the 2 excurrent ribs 
forming only small teeth, not short seise. 
The very lax panicle and the root leaves not being densely tufted 
distinguish A. canuia from A. setacea at first sight.

Stems erect or ascending from a decumbent and usually rooting base. 
Leaves all flat; sheaths nearly smooth, the upper one not more than 
twice as long as its leaf: li-'ule oblong-lanceolate, long, scarcely 
laciniate. Panicle lanceolate -oblong, lax, rarely dense, open during 
flowering, and irregularly closed afterwards; panicle-branches rather 
long, generally longer than the internodes of the racliis, rough, the 
longer ones bare of florets at the base for less than half their length, 
tlie shorter sometimes with florets nearly or quite to the base. Glumes 
broadly lanceolate, acuminate, the lower one a very little larger than the
