BOTANY, 15 



Pentstemon Thurberi : shrubby, luuch branched, very smooth ; tube of the corolla very short, 

 tubular-funnelform ; lobes of the limb ovate ; sterile filament smooth. Burro mountains. New 

 Mexico ; August. This is No. 1056 of the collection of Mr. Thurber, who found it in Sonora 

 and indicated to me the characters in which it differs from P. ambiguus. The tube of the 

 corolla in the latter is nearly three-fourths of an inch long, and curved, while the whole length 

 of the flower of the former is not half an inch. 



Pextstemon linarioides. Gray, Mss. Chiricahui mountains, New Mexico ; August. This 

 species will be described in the botany of Capt. Whipple's Pacific Railroad Report. It belongs 

 to the section Cepscosmus, and is No. 1472 of Wright's New Mexican collection, and No. 331 

 of Thurber's.
