 one-fourth of an inch broad, on short, slender peduncles; each flower con- 

 sisting of three oblong divisions to the corolla, three stamens inserted on

 Louisiana, mostly near the coast. Flowering from June to August; in 

 New York usually flowering in July. 



Several closely related species are recognized by botanists. X y r i s 

 f 1 e X u o s a Muhlenberg, of about the same range, has the scapes bulbous- 

 thickened at the base. Xyris m on tana H. Ries, in bogs from Nova 

 Scotia to Michigan and Pennsylvania, is frequent in the mountainous 

 parts of New York, and resembles very closely the Carolina Yellow-eyed 

 Grass.
