Distribution : eastern Oregon. Type : Nevius from Baker City. 

 Specimens examined: 



Oregon: Blue Mountains, May 21, 1885, Howell 345 (Gray 

 Herb.); Baker City, 1875, Nevius (Gray Herb., type). 



A very beautiful and quite distinct species that has been col- 

 lected but seldom. Because of its striking appearance this scarc- 

 ity in herbaria must indicate a very limited range or infrequent 

 occurrence.

True T. brachycarpum is not so common a plant as formerly 

 supposed. Most of the material that has previously been referred 

 here is now assigned to T. crispum. The original drawing of this
