of coriaceous, overlapping bracts or scales. Flowers bright yellow, about 

 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 

 the corolla and a three-branched style. Flowers appearing from the axils 

 of the bracts comprising the spike. 



In swamps, bogs and borders of streams from Maine to Florida and 

 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 

 flexuosa Muhlenberg, of about the same range, has the scapes bulbous- 

 thickened at the base. Xyris montana 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.

 from the crown, i to 3 inches long. Flowering scapes weak, twisted, 

 usually about seven-angled, i to 8 inches tall, or when submersed, both 

 the leaves and the scapes considerably elongated, bearing at the summit 

 a small subglobose head of woolly white flowers, interspersed with numerous 

 bracts; most of the flowers staminate and about one-eighth of an inch 

 long, the few pistillate flowers scarcely more than half as large. 



In still water and on shores of ponds, lakes and streams, usually where 

 it is sandy, from Newfoundland to Minnesota, Florida and Texas. Usually 

 in flower in this State in July and August. In the south are numerous 

 other species of this and related genera.
