610 CONTRIBUTIONS FROM THE NATIONAL HERBARIUM. 



4. Sambucus vestita Woot. & Standi. Contr. U. S. Nat. Herb. 16: 175. 1913. 

 Type locality: Ice Canyon above Van Pattens Camp, Organ Mountains, New 



Mexico. Type collected by Standley, June 11, 1906. 



Range : Southern New Mexico and Arizona. 



New Mexico: Mogollon Mountains; San Mateo Peak; Black Range; Organ Moun- 

 tains. Canyons and along streams, in the Transition Zone. 



The plant is common in the canyons of the southwestern mountains. It is related 

 toS. neomexicana, but has smaller flowers and pubescent instead of glabrous branches. 

 In habit the two are dissimilar, for S. neomexicana has usually a well-developed trunk 

 with branches, while S. vestita consists of a clump of mostly simple shoots.
