Type in the U. S. National Herbarium, Kearney and Shantz No. 3218, 

 collected on the sandhills :'. miles west of Toele, Utah, growing with 

 Psoralen lanceolata. 



This is one of the many interesting species collected by Messrs. Kearney

 inflorescence [a decompound dichasium], which latter forms fully the 

 upper half of the plant. The lower branches of the inflorescence are 

 straight, forming with one another an angle of about 15° more or less.
