78 TRIANDRIA— DIGYNIA. Phleum. 



W'liolc plant bright green. Root of several strong whorled fibres. 

 Stem 8 — 18 inches high, very smooth, leafy, branched from the 

 bottom, as well as in the upper part. Leaves roughish, pointed, 

 erect, with slightly swelling sheaths. Stipula oblong, generally 

 torn. Panicles terminal, solitary, erect, 2 or 3 inches long, 

 very dense, cylindrical, or somewhat tapering, rough to the 

 touch, when bent to one side proving to be much branched and 

 subdivided, consisting of innumerable little tumxdjlowers, whose 

 calyx-valves are roughish, each tipped with a small rigid point ; 

 the keel often toothed, but never fringed ; the inner edges mem- 

 branous and abrupt. Cor. of 2 unequal, oval, ribbed, somewhat 

 downy, glumes. Stam. and Styles capillary. Seed cylindrical, 

 minute, loose. 



The synonyms in Villars and Hudson, as well as those of older 

 authors, are, as Schrader observes, to be received with caution. 

 I submit to the correction of the great author last mentioned as 

 to the specific name, which is perhaps preferable to our original 

 one, and certainly far more generally adopted.
