rocks, on mountains about the grand rapids of the Columbia, in Northern America 
and sent to the Horticultural Society. It flowers the greater part of the summe:

rockery, the smallness of its flowers rendering it an appropriate associate for alpin

Messrs. Chandler, of Vauxhall, for the opportunity of preparing a drawing. 
Pentstemon is from pente, five, and stemon , a stamen, there being five of tbos 
organs in each flower,™ four perfect, and one imperfect.
