gravel on mesas. Blooms in May and fruits in June. I alter the 

 name because there is another Cyinopterus Joiicsii. Oil tubes 

 similar but 8-12 on the commissure. Plate XXV, figs. B i, B 2. 



Cymopter2is Parry i (C. &. R.) Colopiera Parryi C & R. Rev. 

 Umb. 50. Leaves bipinnate and divisions usually small, involucre 

 absent (?), wings of fruit scarcely corky thickened, and dorsal 

 ones almost equally developed, oil tubes one or two more than 

 in C. N'ewberryi. Northwestern Wyoming, Parry. Plate XXV, 

 figs. A I, A 2. 



To the above is doubtless to be referred Cymopterus dccipicns, 

 Jones, Zoe ii, 246, but this differs in having a hyaline involucre, 

 though small, corky lateral wings, and well developed dorsal 

 ones. Southeastern Utah, on clayey and sandy plains, growing 

 along w'ith C. Neicbej'ryi, and seeming to pass into it. It flowers 

 in May and fruits in May and June. Though I first described 

 this as often without an involucre, I find traces of one in every 

 plant in my collection as given above. It would be readily over- 

 looked by almost anyone m most cases. 



Since the above was written Miss Eastwood has sent me, from 

 Southeastern Utah, a specimen of undoubted C. Parryi, every 

 peduncle of which has an involucre as described above. My 

 surmise was therefore correct, and C. decipieiis may be sup- 

 pressed, being a synonym for C Parryi. 



In the plate accompanying this article the wings of C. glomer- 

 atiis fig. C, were made too narrow at the apex. Seeds of other 

 species figured are C. lon^ipes fig. F, C. Ibapeiisis fig. E, C. Jo7iesii 

 fig. G. The figures are taken from the seeds withoirt soaking 

 them up as that generally swells them out of all proportion and 

 distorts the wings. I have made no effort to show other seed 

 characters beside the wings. 



Cymopteriis glaiicus, Watson. I see that Coulter and Rose in 

 their Rev. Umbelliferae, p. 81, say that my No. 1688 is this 

 species, but it is not. It is probably Cyinopterus Ibapensis, but is 

 only in flower. C glaucus is my No. 1687. My numbers never 

 have been duplicated, so it is not necessary to give either the 

 year or the locality of collection, the number tells it all. It is 

 probable that some one has transposed the labels of the two
