Mexico : Bejar, Berlandier 1620 ! 



Leaves, ± ^ cm, X 3 cm., with petiole not exceeding 7 mm. 

 Stipules ± 3 mm. long. Peduncles ± 2-5 cm. Calyx, 2d mm. 

 long. Corolla-tnhe 3-3-3 mm. long; lobes barely I'o mm. Style 

 exserted up to 1'5 mm. Ileails, not reckoning the corollas, 7 mm. in 

 diameter. 



This species is at once distinguishable by the remarkable shortness 

 of the corolla, as well as by the small size of the heads. The sheet in 

 the National Herbarium, l)earing the above type, contains also a plant 

 collected in Texas by Berlandier (No. 1737), named " CejjJialaitfhus 

 occidentalis /3. hrachypodus DC." The tiowers upon this latter 

 specimen are, however, too young for the species to be identitied ; 

 and in any case the description of the variety in question (DC. Prodr. 

 iv. 539) is inadequate altogether. The Texas plant is probabl}^ a 

 variety of C. occidentalis ; it is not identical with my new Mexican 

 species.

Tliis species differs from both its nearest alHes, C occidentalis and 

 C. salicifolius, especially in the much greater length of the corolla- 

 tube, as well as in the shape of the leaves. The latter measure about 

 8 cm. X 2'4 cm. on an average, with stalks not exceeding 7 mm. in 

 length, and stipules 3 mm. long and 3 mm. broad at the base. Heads, 

 about 8 mm. in diameter, exclusive of the corollas. Calyx 3 mm. 

 long. Corolla-tnhe 11-12 mm. long; lobes 1-Smm. long. Terminal 

 peduncles, 4*5 cm. long.
