TRIANDRIA. DIGYNIA. Aira. 137 





A. Leaves like bristles : sheaths rough ; flowers in a pani- canes'cens 



cle : awn not longer than the calyx. 



Plate XXIV. — Fl. dan. 1023 ; hut the panicle much 

 larger and more expanded than as it grows with us—Lob.

Awns encompassed with little teeth in the middle part, brown 

 and thick below, but whitish, slender, and somewhat club- 

 shaped above. After flowering the panicle rises higher out of 

 the sheath ; before flowering it resembles a spike. This is paler 

 than most other grasses, and from that circumstance may be 

 distinguished at first sight. Linn. Panicle scarcely ever coming 

 out of the sheath. No plant alters its appearance more com- 

 pletely when cultivated than this, growing much larger, quite 

 upright, and losing entirely its grey colour. Mr. Woodward. 

 From 4 to 6 inches high. Root-leaves very slender. Stem-leaves 

 broader. Panicle spike-like, purplish, \\ inch high, £ inch 

 broad. Caly x husks unequal ; (PI. 24, a.) Awn the length of 



the shorter husk, nearly twice as long as the blossom. The 

 structure of the awn is remarkable, the lower half is thicker, 

 opake, and yellow brown, the upper half very fine, whitish, semi- 

 transparent, fixed to the centre of the broad top of the opake 

 woody part, which is encompassed with very minute teeth.

A. Leaves like bristles : sheaths smooth, angular with fur- prae'cox* 

 rows : panicle spike-like : awn taller than the calyx.

From 2 to 5 inches high. Spike-like panicle 1 to if inch 

 long, less than £ inch broad. Bloss. valves cloven at the end, 

 nearly as long as the calyx. Avon twice as long as the calyx, in 

 structure similar to that of the A. canescens, but wants the broad 

 top to the lower opake part. Sufficiently distinct from the A. 

 canescens, and flowers earlier. ,
