_Tecognized as a hyaline border or involucre. In both of the 
above species this involucre is one-quarter to two lines wide and 
often quite evident as much so as in Cymofterus montanus the 
more reduced forms. In Cymopterus decipiens 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 decipiens, 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 aninvolucre 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. mon/anus 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. Newderryi 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. 
CymoprERus, § coLopTERA (C. & R). Flowers yellow, 
lateral wings of seeds thickened in the middle so as to form a 
ting, oil tubes numerous, involucre usually minute, hyaline. ©

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
