﻿EUSTACHYS IN NORTH AMERICA 439 



Sandy soil, Texas. Readily distinguished from C. verticillata 

 by its shorter and less numerous spikes, broader empty scales, 

 shorter awns, and smaller and differently shaped fourth scale. 



The following specimens belong here : 



G. C Nealley, 1885; Hockley, F. W. Thurow, 1891 ; 

 Nueces Co., A, A. Heller, 1894, Mar. 21, no. 1471 (the type),

Chi oris verticillata var. iiitermcdia Vasey ; L. H. Dewey, 

 Contr. U. S. Nat. Herb. 2 : 528. In part. 1894. Not C. inter- 

 media A. Rich. 185 1. 



Culms 2-6 dm. tall, compressed, simple at first, finally 

 branched at the decumbent base and rooting at the lower nodes ; 

 nodes 2 or 3 : culm leaves 2 or 3 ; sheaths usually much shorter 

 than the internodes, compressed, keeled ; ligule a scarious ciliolate 

 nng less than 1 mm. wide ; blades 1-10 cm. long, 2-4 mm. wide, 

 linear, obtuse, rough on both surfaces and on the margins : inflor- 

 escence exserted, the axis 1.5 cm. or less long, angled, the angles 

 hispidulous; spikes 10-16, 3-7 cm. long, finally widely spreading 

 and often more or less flexuous, spikelet-bearing to the base : 

 spikelets, exclusive of the awns, 2.3-2.8 mm. long; scales 4; 

 °uter empty ones acute, the first scale about one half as long as 

 the second, which is about 2 mm. long ; third scale 2.2-2.7 mm. 

 ° n g, in side view elliptic and .8-9 mm. broad, about equilateral, 

 jhe callus pilose, the lateral nerves strongly pilose their entire 

 length with short hairs, the midnerve less so to the base of the 

 JWn, which is inserted just below the apex and is 1.5-3 mm. long, 

 he palet about as long as the scale ; fourth scale 1. 5-1.7 mm. long, 

 ln Slc * e y iew obcuneate or rarely triangular and I— 1.2 mm. broad, 

 3-nerved, the midnerve straight, the lateral nerves much curved, 



ranching at the middle, thus making the scale appear 5 -nerved at 

 ^he truncate apex, the extranerval portion triangular, .5 mm. wide, 



e awn inserted just below the apex, 1.5-2 mm. long. 



y ground and shady river banks, Texas. Distinguished from 

 verticillata by the shorter spikes, shorter and broader outer 

 ^Pty scales, and the broader and more nerved fourth scale ; the 

 re nt shape and the much greater width of this latter organ, to- 

 gether with its much more spreading awn, also serving to separate
