The Tblafpi arvenfe filiquis lath of C. Bauhlne, and the prefent fpecies, are the two whofe feeds have been felefled 
from this numerous gams for medicinal ufe. Tilde appear to have been ufed indifcriminately ; and fometimes the 
leeds of the common Clefs (Lapdmmfatmum) have been fubftituted for both. Their virtues appear to be oret v 
imnlar t Rutty prefers thole ot the arvenji, as being the moft aftive : they certainly have much more ot the allia- 
ceous talte than thole ot the campejtre. 1 
In the prefent practice they are rarely made ufe of any otherwife than as ingredients in the Venice Treacle and 
Mithridate, though lome recommend them in different diforders, preferably to the common Muftard. with which 
they agree nearly m their pharmaceutic properties. Lewis, Mat. Med. p. 647. 
The prefent lpecies is not an unulual inhabitant of corn-fields; neverthelefs it is rather a fcarce plant with us 
We have noticed it in the greateft plenty about Coomb Wood, near Kingfton. Dr» Goudenough informs me it is 
not uncommon in Gunneribury Lane, near Ealing. ’ 
It flowers in June, and ripens its feeds in July and Auguft.
