were it not for its propensity to fill the whole ground 

 with plants from its abundant suckers, would be very de- 

 sirable. 



C. pufotfscens. Downy Bindweed. A Chinese species 

 with elegant double rose-colored flowers, which was in- 

 troduced into our gardens a few years ago, but which has 

 proved a great nuisance. In my garden, it would throw

 which they are separated on account of the two broad 

 leafy bracts which surround the calyx. 



CAMPANULA, BELL-FLO WEB.

Campanula rotundifolia, Hare-Bell. An indigenous 

 species, which is very pretty and worthy of cultivation; 

 It is found on the banks of the Merrimac river, above 

 Lowell, and in many other places. It has nearly round, 

 heart-kidney, crenate radical leaves, from which the spe-
