(A) Bladder Campion (Silene latifolia) (European). 
We have several Campions, some natives and some in¬ 
troduced. The present species was brought to us from 
Europe. It has very unusual blossoms, in that the 
calyx is very inflated, almost globular and handsomely 
marked with darker green, so as to often give it a very 
similar appearance to that of the citron melon. The 
five white petals are cleft in twain for nearly their 
whole length. 
It is a common escape from gardens and may be 
found blooming from June to August along roads or in 
dry waste places from Quebec to Minn, and south to 
Va. and Mo. 
(B) Evening Lychnis; White Campion (Lychnis 
alba) (European). This is another attractive species 
introduced from Europe. The petals are white, deeply 
cleft and crowned at the base with little petal-like di¬ 
visions; the calyx is inflated and often deep pink on 
the ribs. The leaves are smooth edged and oppositely 
on the stem that grows from one to two feet high. 
Escaped from gardens, from Me. to N. J. and west to 
Ohio.
