narrow, racemose, 8-12 cm. loug. Spikelets 1-flowered, first glnme- 

 narrow, scabrid, 1.7 mm. long, second narrowly obovate, 3 mm. 

 long; floral glume scabrous, elliptical when spread, 2.2 mm. long, 

 sometimes bearing a bent awn on the back 2 mm. long, starting 

 one-fifth of the way below the apex ; sometimes 1-2 short bristles 

 on the rachilla. Labelled E. oMusata var, hyhrida. 



Judging from the spikelets, it is nearly allied to E. oMusata; 

 from the leaves and panicle to E. Dudhiji. Whether it is a sport, 

 or a hybrid between Eatonia ohtusata or E. Diidleyi and Trisetum 

 is still a question. Those interested will do well to read Dr. Vasey 

 as above, in which he speaks of finding near Alexandria, AHrginia, 

 a hybrid grass nearly intermediate between E. Pennsylvanica Gray 

 and Trisetum palustre L.

Culms very slender, 60-75 cm. high. Sheaths clothed with very 

 short soft hairs; blades of the culm abruptly acute, 3-5 cm. long, 

 those of the sterile shoots scabrous, 8-15 cm. loug, 2-4 mm. wide. 

 Panicle very slender, 8-15 cm. long, rays few, short, and mostly 

 appressed. Empty glumes equal, 2.2 mm. long, first linear-obo- 

 vate, second rhombic-obovate when spread; floral glume concave- 

 oval when spread, 2.1 mm. long; rachilla scabrid. It differs from 

 E. Pennsijlvanica in having shorter cauline leaves, lower sheaths 

 shorter, pubescent, first glume wider and more obtuse, second glume 

 shorter.
