recognized as a hyaline border or involucre. In both of the 

 above species this involucre is one-quarter to two lines vs^ide and 

 often quite evident as much so as in Cymoptcrus montanus the 

 more reduced forms. In Cymopterus decipieyis the involucre is much 

 more evident as a rule, and in some cases it is as long as the 

 pedicels, that is its lobes which are lanceolate and acuminate and 

 green. Cymopterus decipiais, Jones is a true Coloptera, and I 

 doubt not that it will fall into Coloptera Parryi eventually as the 

 thickening' of the wings is of so little account, while I think 

 that Coloptera Parryi will be found to have an involucre as I have 

 described above. 



Since there is no character assigned to Coloptera by Coulter 

 and Rose that holds, it must fall into Cymopterus where all its 

 affinities are, where it belongs in habit, structure of the seeds, 

 involucre and involucels. The roots also are those of Cymop- 

 terus being deep seated and tuberous like C. montanus and C. 

 glomeratus. Fortunately this reference will not increase the 

 species nor require much change in names, and in the end will 

 I think reduce all the described species to one. I have not now 

 enough forms to make me feel sure that C. Newberryi and C. 

 Parryi pass into each other, as many of my apparently connect- 

 ing forms are without mature fruit. However, the following 

 disposition of the species will hold as far as it goes. 



Cymopterus, § coi^optibra (C. & R). Flowers yellow, 

 lateral wings of seeds thickened in the middle so as to form a 

 ring, oil tubes numerous, involucre usually minute, hyaline.

 Acad, ix, 145, Coloptera Newberryi C & R. Rev. Umb. 49. 

 Leaves pinnate and pinnae toothed or lobed, lateral wings only 

 developed. Southern and Southeastern Utah on clayey or sandy 

 plains. Flowers in May and fruits in May and June. Oil tubes 

 4-8 in the intervals, 8-10 on the commissure. Plate XXV, fig. D. 



Var. alatus. Coloptera JonesiiQ,. & R., Rev. Umb. 50. Dorsal 

 wings also developed and thin or corky thickened. This shades 

 into the type and is little more than a form of the species hardly 

 deserving to rank as a variety. Frisco and Milford, Utah, in
