inches long; sheaths rather loose, mostly shorter than the inter- 
nodes, the lower scarious ; ligule ¥% lines long; panicle slender, 
lax, 3-6 inches long, primary branches 2~3 rarely more at each 
node of the main rhachis; spikelets ovate, 2-3 lines long, 3-5- 
flowered ; rachilla often flexous; empty glumes sub-equal, 3- 
nerved ; flowering glumes strongly carinate, lanceolate, 5-nerved, 
silky-villous along the margins and keel and with a copious, long 
web at the base.—Ill., Tenn., Kansas.

Kunth is cited by Dr. Wood as the author of /.Shorti, but I 
do not find this name in any of Kunth’s writings. Probably it is 
an herbarium name. An examination of Wood’s herbarium or 
the herbarium of Dr. Short, which is at the Philadelphia Academy 
of Natural Sciences, may serve to settle this point. In later writ- 
aod Wood reduced the species to a variety of / nutans. In his 
Flora Atlantica”’ (1879), he calls it / mutans var. palustris (p. 
399). It is, I think, a good species, readily distinguished from 
vutans by its less elongated panicle, more crowded and much 
broader spikelets. : .
