 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. — Jalisco: Guadalajara, C. G. Prin-

 Mohinora, 1 September, 1898, E. W. Nelson, no. 4895 (type, in hb.

 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.
