Cymopterus Parryi (C. & R.) Jones. Coulter and Rose 

 state that this species is said to come from the mountains in- 

 stead of the plains (p. 182), but they do not give their author- 

 ity for it. It is an error, at any rate, for the plant grows on the 

 adobe plains of the Bad Lands of Wyoming, where I col- 

 lected it. at Granger and Carter, as referred to on same page. 

 1 see nothing to separate this from C. glomeratus; as a rule the 

 leaves are more reduced as well as the fruit wings, due to the 

 poor soil on which it grows, and yet with all this isolation for 

 ages past the same kind of leaves and fruit occur on specimens 

 gathered along with the type as are found in C. glomeratus, 

 and so the species must fall. I have it from Ketchum, Idaho, 

 the most western locality reported so far. 



Cymopterus Fendleri Gray. I still maintain that this 

 cannot be separated from C. Newberryi by any character that 

 sticks. The characters given by Coulter & Rose do not hold. 

 The involucre is as often absent as present ; you can get in the 

 same locality a complete transition in the leaves. It is not al- 

 ways easy to separate this from C. glomeratus.

 This should be kept up as a variety. 



The new genus Aulospermum C. & R. is a curious mixture 

 for splitters. As arranged by them it contains two groups 

 having little affinity for each other, but great affinity for two 

 other genera of theirs. This group of A. longipes, glaucus ?, 

 Watsoni, and Ibapensis, is characterized by havisg deep and 

 thick vertical tuberous roots and mostly single and long 

 fleshy prolongations connecting with the surface, and there 

 single or few branched crowns on them which when young 

 rest on the surface and the leaves spread out in a fiat rosette 

 till after flowering time, the foot then elongates and raises the 

 wliole crown and leaves and fruiting pecuncles often a foot in 

 the air, but the plant is acaulescent. The leaves are fleshy as 

 v/ell as the whole plant, and soft, glaucous, with blunt lobes, 

 and with large hyaline non-fibrous root sheaths, without pe- 

 tioles when dead. The fruit is very thin-winged, the cross sec- 

 tion of the wings being filiform and of almost the same width 

 throughout, though a shade wider at insertion and thinner at
