6b. Spikelets 2 — 3 mm. long; panicles 4 — 5 mm. in diameter; awns con- 

 cealed in the glumes. Fig. 194. 



AlopecuTus aequalis Sobol. 



Perennial; culms weak and sprawling. 

 15 — 60 cm. long; leaf blades 1 — 4 mm. 

 wide; panicles cylindrical, shattering very 

 readily; 2 — 7 cm. long. The plants are 

 frequent on wet ground in swamps or along 

 small streams. Succulent and probably 

 good forage. May — June.

 WOODREED Cinna aiundinacea L. 



Perennial; culms in small tufts, 100 — 150 

 cm. tall; panicles large, 15 — 30 cm. long, 

 drooping, the very flat spikelets shining, over- 

 lapping. The leaves are sometimes over 1 

 cm. wide. This common woodland grass is 

 foimd in moist forests. August — October.
