MR. F. N. WILLIAMS ON THE GENUS SILENE. 109 
to justify, for the records in many localities are only such as would indicate 
it as an escape from gardens, where it is generally in cultivation, or in a 
state of semi-cultivation, and otherwise imperfectly taturalized. In 
England it is found occasionally by river-sides, in cornfields, and in waste 
places, but apparently only where it has escaped from gardens; and does 
not seem to be permanently naturalized. The pretensions of this species 
to a place in the British flora seem very slight. Dr. Richardson informed 
Dillenius that it grew on the banks of the River Dee half a mile below the 
city of Chester, but no one has confirmed his account. In the appendix to 
Hooker’s ‘Student’s Flora,’ it is mentioned among the excluded species as 
a casual. Similarly in Belgium, Denmark, and Sweden, it occurs sub- 
spontaneously. In the United States it is occasionally found on roadsides 
and in fields, having escaped from gardens; it has also been introduced 
into India and Brazil. In various localities in the northern provinces of 
Spain it is an uncertain denizen. The specimens found in Luxemburg 
appear to be naturally wild, as certainly the plant occurs under natural 
conditions in the neighbouring Prussian province of Rhine-land.
