One of the smaller species, named in honour of the zealous aud indefatigable trareUerj Mr. Charles 
Wriglit, who collected it in four different localities of New Mexico (Wright, 1700 aud 1701 !), and between 
Western Texas and El Paso, N. Mexico (Wright, 567 and 568 !) ; Hartweg found it at Zacatecas, aud I in 
the neighbourhood of Durango, where it seems by no means abundant, as I only noticed it ouce. The size 
of the whole plant, and especially that of the leaves (as well as their form) vary extremely ; the smallest 
leaves are scarcely 4 lines long, and 3 lines broad, the largest about 1^ inch long, and 1 inch 3 lines broad. 
The colour of the corolla is a dull brown,
