9. XYRIS CAROLINIANA, Walt. 
X. Caroliniana, Walt. F\. Car. 69 (1788). 
X. elata, Chapm. Fl. S. U.S. 501 (1860). 
x serotina, var. Chapm. Mss. in Herb. Col. Coll. 
X. graminifolia, Chapm. Mss. in Herb. Col. Coll. 
Scapes solitary or clustered, twisted and two-edged abov 7 
1-2 feet high; leaves linear or linear-lanceolate, 4-15 inch 
long; spikes globose or ovate, or sometimes oblong ; scales 
brown, becoming curled and the margin lacerated with ag 
lateral sepals linear, the upper third of the narrowly winged ke 
incised-serrate. 
Forms found in New England agree with Dr. Chapman’s Ye 
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.
