ment, but always with more or less of a hyaline margin ; 

 fruit about 6" long, nearly round to oval and deeply 

 emarginate above; wings 2-3" wide, with a narrow, corky 

 margin next the seed; otherwise very thin; oil tubes 3-4 

 in the intervals and 8 on the commissure, not evident ex- 

 ternally; leaf sheaths enlarged at the base and stems 

 covered below with long, hyaline leafless sheaths ; leaves 

 from fully to barely bipinnate, with obovate, often lobed 

 divisions, always glaucous and thick, 3—4' long, mostly 

 ovate in outline, with petiole equaling or exceeding the 

 blade.

An examination of the material referred to this species 

 in the National Herbarium shows that the specific char- 

 acter does not agree with the generic character given by 

 Coulter & Rose under Coloptera, the flowers being white 

 instead of yellow. The other two species described by 

 them, as I have already indicated in Zoe, 4, p. 49, have a 

 minute hyaline involucre, while this species has no trace 

 of any, and therefore must be compared with Cymopterus 

 glomeratus and not with C. Fendleri. On comparison 

 with a large suite of specimens of C . glomeratus there is 

 absolutely no character of leaf, habit, or inflorescence to 

 separate this species from that. The only character, and 

 that a variable one, lies in the wing of the fruit, which in 

 some specimens is quite thick on the outer edge and with 

 only a rudimentary thin prolongation beyond, but in other 

 specimens the prolongation is more pronounced. In sorne 

 specimens of C. glomeratus in the National Herbarium from 

 the plains, the. corky portion of the wing is quite narrow
