Neillia Torreyt ranges over a considerable area of North 
America, from British Columbia, along the Rocky Moun- 
tain region, at elevations of six thousand ft. to ten 
thousand ft., to New Mexico. I collected it when travel- 
ling with Dr. Gray in 1879, at La Veta, in Colorado, at 
above nine thousand ft. elevation. It forms, with other 
American species and a Manchurian (N. amurensis) a very 
distinct section of Neillia with corymbose flowers and 
other characters, regarded as a genus and named 
Physocarpa by Rafinesque, altered to Physocarpus and 
retained as a genus by Maximovicz and others.
