 ennial, with flattened stems 6-12 dm. (2°-4°) high, long leaves, glabrous or 

 pilose, compressed sheaths, and spreading panicles. Spikelets (5, d) lanceolate, 

 acuminate, curved, 3 mm. {U") long, on short, scabrous pedicels; the acute sec- 

 ond and third glumes about one-fourth longer than the elliptical-oblong flower- 

 ing glume (e), which usually bears a minute tuft of hairs at the obtuse apex.— 

 Low woods and thickets, marshes and banks of streams, Pennsylvania to 

 Illinois, Missouri, Indian Territory, Texas, and Florida. July to October. 



In luxuriant forms the panicle is often G dm. (2°) long, with widely spreading 

 branches. In variety pubescens Vasey, Contr. U. S. Nat. Herb. 3 : 35. 1892, the 

 panicle branches are more slender and the lower leaves and sheaths pubescent. 

 Variety AXGUSTA Vasey, I.e., has villous lower sheaths and very long, erect, 

 rigid leaves. Variety densiflora Vasey, 1. c, has broader leaves and narrow 

 densely flowered, glomerate or interrupted panicles.
