﻿Bicknell: Two new Grasses 105 



an abundant growth of Savastana odorata, its remaining fertile 

 culms having the leaves and panicle dried and brown. S. Nashh 

 was still in flower at the same spot on August 8th and withering 

 specimens were collected September 18th. 



This grass, although closely related to Savastana odorata (L.) 

 Scribn., differs conspicuously in various characters and presents a 

 widely different appearance. Its fertile culms are much taller with 

 more numerous and very much longer leaves, which are narrower, 

 especially at the throat, and with closer sheaths, while the pani- 

 cle is larger and incomparably looser. The spikelets are nar- 

 rower and slightly longer, their very delicately membranous outer 

 glumes more unequal, less distinctly nerved, narrower and more 

 gradually acuminate with their tips mostly straight at maturity 

 instead of often outcurved as in S. odorata / the flowering glumes 

 are narrower and more acuminate and often more distinctly awned 

 and ciliate. 



Not the least noteworthy thing in regard to this grass as com- 

 pared with S. odorata, is its much later flowering period — July to 

 September ; S, odorata, the earliest flowering of our native grasses, 

 blooming from the middle oi April till June. 



I take pleasure in naming this interesting grass for Mr. George 

 Nash, with whom I was enabled to make a study of it in the 



V 



field a few days after its first discovery. 



Chaetochloa versicolor. 



Perennial from an intricately short-branched and somewhat 

 stoloniferous rootstock ; not at all or but slightly tufted ; culm 

 6-12 dm. high, ascending or suberect from an assurgent base, 

 slender, often somewhat zigzag below, simple or bearing a few as- 

 cending branches ; leaves long and narrow, 1-3-5 dm - lon £» 2 "^

the apex, pale green or glaucescent, becoming much colored with 

 purple, smooth, or slightly roughened on both surfaces toward the 

 scabrous apex, the margins minutely serrulate-scabrous except 

 towards the very smooth base which is often finely canescent in the 

 throat but never pilose ; ligule a very short, dense fringe of scarious 

 hairs ; sheaths very smooth and glabrous, compressed and keeled, 

 the lower mostly longer than the internodes, the upper ones 

 shorter; nodes dark; basal internodes often less than 3 cm. long, 

 those above gradually longer, the upper ones often 1-1.8 dm. in 

 length; peduncles very slender, exserted 1. 5-3-5 dm., slightly
