angustifolia Mart. & Gal. 1. c. 29 (1845) is considered a synonym of 
this, but the name is preoccupied. The range of this species, if all that 
seem to agree with the description and authenticated specimens are 
correctly identified, is from South America to N. W. Mexico. The 
type was collected probably in the State of Hidalgo near Real del 
Monte. Specimens in hb. Gray. — Jaxisco: Guadalajara, C. G. Prin-

U.S. Nat. Mus. and hb. Gray). This species is related to C. scorzo- 
nerifolia, but differs in having much larger almost smooth leaves. The 
corolla is dissimilar, with three rather long acuminate divisions instead 
of five short teeth. C. Nelsonii is a showy plant with a large subcap- 
itate spike of scarlet bracts and flowers terminating the tall stems.
