9- Xyris Caroltniana, Walt. 



X. Caroliniana, Walt. Fl. Car. 69 (1788). 



X elata, Chapm. Fl. S. U. S. 501 (i860). 



X. serotina, van Chapm. Mss. in Herb. Col. Coll. 



X. graminifolia, Chapm. Mss. in Herb. Col. Coll. 



Scapes solitary or clustered, twisted and two-edged above, 

 1-2 feet high; leaves linear or linear-lanceolate, 4-15 inches 

 long ; spikes globose or ovate, or sometimes oblong ; scales 

 brown, becoming curled and the margin lacerated with age ; 

 lateral sepals linear, the upper third of the narrowly winged keel 

 incised-serrate. 



Forms found in New England agree with Dr. Chapman's type 

 of elata, and if this species could be maintained would extend 

 its range. This, however, seems doubtful, as forms intermediate 

 between Caroliniana and elata exist, and show that the two pass 

 into each other.
