_ This seems to be a common Mexican shrub, for it occurs 
in most collections from that country. In appearance it is 
extremely like Arctostaphylos tomentosa, and an insufficient 
examination of dried specimens led to the belief that it is a 
mere variety of that plant. The fresh specimens shew, how- 
ever, that in addition to a want of the long beard-like hairs 
of the branches of A. tomentosa, this species has the awns 
of the anthers longer than the anthers themselves, and only 
seven cells to the ovary instead of ten. 
Our drawing was made in the garden of the Horticultural 
Society, to which it had been introduced by Mr. Hartweg, 
who found it in Mexico, at an elevation of 7000 to 9000 feet 
above the sea, forming an evergreen shrub six to eight feet 
high, with a reddish brown smooth stem and branches, and 
very hard wood. It was common about Guanaxuato, Real del 
Monte, Bolanos, and Oaxaca, and is known there under the 
name of “Pinguica” or “ Manzanilla,” according to that 
Botanist. 
Up to the present time it has proved, in cultivation, to be a 
neat little half-hardy or possibly hardy evergreen shrub, grow-
