lNGIum longtfolium, Cav. Ic. 6. t 555 ; BC. Prodr. 4. p. 95 1 Las Play 

 Springs, near the Sierra de los Animos, New Mexico; Oct. (1103.) — The radic 

 leaves are 3 or 4 feet long, 4 or 5 lines wide, tapering to a point, soft, resembli] 

 those of a large Sparganium ; their margins entire and naked, or rarely with one 

 two setiform teeth ; these sparingly appear on the similar hut shorter cauline leaves. 

 The scales of the involucre are much shorter than the oval heads, linear-subulate, 

 often resembling the paleae and scarcely exceeding them.
