This species I have seen only as a tall shrub from 3-5 m. high 

 branching from the base into slender upright stems; it is usually 

 found on rocky slopes at an elevation of from 1600-2200 m. It is 

 distributed from the provinces of Coahuila and Chihuahua of Mexico 

 through western Texas and the southwestern half of New Mexico 

 to northern Arizona; it does not seem to occur in northeastern New 

 Mexico or in southwestern Arizona. It shows some variation in 

 the serration and in the number of leaflets and the following varieties 

 may be distinguished from the typical form which has 5-7, rarely 3, 

 lanceolate to ovate-lanceolate leaflets occasionally sparingly serrate. 

 Shrubs with rather densely pubescent and at the same time smaller 

 and broader leaflets apparently represent merely a juvenile form, as 

 I found such foliage only on stunted shrubs without fruit; only once 

 I found a slightly pubescent shrub with a few fruits. Pringle has 

 also distributed sterile branches with pubescent leaves under his 

 number 137 from the Santa Eulalia Mountains in Chihuahua.
