A 



subaristatus. He quotes Michaux's description (who 



describes the plant under 



A. aristulatus) 



adds " v. s. in Herb. Walter." He seems to have seen 

 only Walter's specimen and yet gives a new name to 

 Michaux's plant and refers Walter's plant here doubt- 

 fully. Michaux's plant (from the swamps of Canada) 

 is said to have an erect culm and awn scarcely exserted 



(our native A 



) 



W 



scription calls for a rooting culm and aristate corolla. 

 Moreover Walter says of this, " panicula subspicata," 



as distinguished from «.« culmo spicato erecto 

 pratensis. This species must remain doubtful.

No specimen. Referred to A. stricta Michx. by 

 Elliott and to A. oligantha Michx. by Pursh. 



The 



description applies better to the latter species than to 

 any other species growing in the Southeast. The panicle 

 is few-flowered and loosely branched. Not A. adscen- 



sionis L. from Ascension Island, 

 Linnaeus' description.
