53. Chilopsis linearis Cav. — This species extends from the Rio Grande 
region east of and below the Pecos, through western Texas, New Mexico, 
Arizona, Utah, and Nevada, into southern California. It also extends 
from west Texas and New Mexico down into northern Mexico (Coahuila 
and Chihuahua). Specimens without flower or fruit, and supposed to be 
Salix , collected from a tree of some size at Brownsville, were pronounced 
to be this species by Dr. Coulter. This would extend the range of the 
species to the lower Rio Grande, which is a considerable extension, as it 
has not been recorded from nearer than Ixion county. The tree was 
fifteen to twenty feet high, and bore cone-shaped cecidomyiid galls like 
those of Salix. (84)
