Pink grows on old walls and castles, and is the origin of 
our garden Pink, though but a poor looking specimen by its 
side; it is called Dianthus caryophyllus, Clove Pink, Carna- 
tion, or Gillyflower.

THALAMIFLORZ. CARYOPHYLLACE. 
AGROSTEMMA. (Cocktz.) 
Generic Character. Calyx tubular, with five teeth. Petals 
five, the border undivided. 
AcrostemMa GirHaco. Corn Cockle. A well-known, 
and ornamental plant in corn-fields; the flowers are large 
and purple; the calyx so peculiar that the plant is easily 
distinguished by it, the lower part being tubular and large, 
the upper part divided into very long, narrow leaves, which 
project beyond the petals. The plant grows about two feet 
high, branched, and erect, with long, narrow leaves, and 
every part clothed with silky hairs. Though admired by 
the lover of flowers, it is not a favourite with the farmer, 
for the numerous, large, black seeds are thrashed out with 
the corn, and injure the quality of the grain.
