CONTRIBUTIONS TO WESTERN BOTANY NO, IS 45 



ncglectum is mixed, founded on two genera, but my type specimens are 

 clearly S, reflexum, and not mixed. 



Payson's treatment of Thelypodium, Caulanthus, and Streptanthu^s 

 well illustrates the foolishness of a closet botanist trjdng to monograpli 

 a genus. He evidently has had little first-hand acquaintance with the 

 genera. Watson, in erecting Caulanthus made an admirable statement of 



the differences.

Streptanthus alwa}'s 



has the flattened pcds, often quite wide, and flowers moitly inflated, the 

 oaly aberrant fc-rm being S. longirostris which connects with Thelypod- 

 ium. The placing of lasiophyllum and Cooperi in this genus could net 

 be worse, while the merging of Streptanthus with Caulanthus has ro 

 justification. 



Caulanthus hastatus when critically studied in the field shows all 

 of the characters of Caulanthus and does not justify being put in a sep- 

 arate genus Chlorocrambe of Rydberg, though the flowers are too small 

 for Caulanthus. We do not expect an}'thing else from Rydberg becau.^e 

 he has no generic nor specific conceptions, his inspirational botany hav- 

 ing gone flooey. 



Lesquerella condensata Nelson. Payscn in his treatment of thi^ 

 spcies" pages 211 and 212 still further balls up things which were in a 

 terrible mess before. NeL'^on in describing this species says it is tl(* 

 most common thing in and around Laramie in the spring, and that it is 

 what he has distributed as Draba glacialis. Now what he distributed 

 to mc as Draba glacialis from Laramie is the var. laevis of Payson. Pav- 

 fon without any authority states that the type of L. condensata is Nel- 

 son's No. 4797 from Tipton Wyo. But in the locality where the type 



was described he (Nelson)

 mention his No. 1218 as the tj-pe of the species, which is a part of 

 the type of Payson's var. laevis. Nelson is always a blunderer but we 

 cannot go beyond the original description for authority as to what wa^^ 

 the type of the species when it is distinctly stated there as to what is 

 the type. So the peculiarly hairy form still is unnamed. 



Eventually there will be difficulty in separating this species from L. 

 intermedia. The plant is common on both sides of the Uintas, the type 

 g^ows on the northern side of this range. On the southern side of the 

 ranee from, Dragon (near Mack Colorado) I have found it as far west
