were it not for its propensity to fill the whole ground 
with plants from its abundant suckers, would be very de- 
sirable. 
C. pubéscens.—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

leafy bracts which surround the calyx. 
CAMPANULA,—BEtL-FLOWER.

Campanula rotundif6lia.—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-kiciuey, crenate radical leaves, from which the spe-
