It >yill be recollected that some of our present ■ 
species of Pentstemon were considered as belonging 
to the genus Chelone. A separation of them was 
adopted on account of their possessing an imperfect 
fifth stamen, and on this distinction from Chelone 
the genus Pentstemon is founded. The name, from 
the Greek pente, five ; stema, a stamen, points out 
the circumstance. 
This most attractive American genus has, within 
the last ten years, given to our gardens an abundant 
supply of additional beauties, several of which are 
not yet generally known. We intend ere long in- 
troducing them to our readers, feeling assured they 
will be received with pleasure. 
The Pentstemon gracilis is a small species, but 
very hardy ; and when grown in considerable 
patches becomes a desirable ornament. Being of 
low and unobtrusive habit it should be planted 
near to the front of the border ; and to obtain a 
luxuriant growth, it will be desirable that it be taken 
up every second spring and replanted. A rich 
loam with the addition of a little peat will prove a 
very suitable soil for it.
