cress, sea-kale, etc., and nearly all its members are anti- 
scorbutic. It is, moreover, not lacking in ornamental plants, 
especially in fragrant flowering species.

1. MATTHIOLA. 
This genus includes all the different races of Stocks. Its 
distinctive characters are: entire or sinuate leaves, large flowers, 
the petals having long claws, a nearly cylindrical pod, connivent 
stigmas thickened or horned at the back, and thin flat 
numerous seeds. About thirty species, chiefly from the Medi-

1. AM. ineéna—This is the sub-shrubby biennial species 
from which the Brompton and perhaps the Queen Stocks 
have descended. It is an erect hoary plant, 1 to 3 feet high, 
with oblong-lanceolate entire leaves and large white, crimson, 
violet, purple double or single flowers. AL. fenestiilis, Giant 
Cape Stock, is referred to this species by some authors. A 
native of the West of Europe and the Levant, and also found 
on cliffs in the Isle of Wight. 
2. df. annwa.—The Ten-week, Intermediate, and other 
garden annual varieties of Stocks belong to this species. This 
has produced innumerable varieties, pom pure white, lilac, 
gee rose, and crimson to purple. Mediterranean region. 
MM. Groen. The Wallflower-leaved Stock.—The foliage 
of re instead of being hoary and downy, is of a bright green, 
closely resembling that of the Wallflower. This Sidhu: some 
white and yellow ate varieties. South of Europe.

fragrant at night, but closed during the day. It has a two-horned 
pod. It flowers during the Summer months. South of Europe. 
2, CHEIRANTHUS. 
Herbs or undershrubs with bipartite hairs. Leaves entire or 
toothed. This genus differs very slightly from the last, distin- 
guished by having a more flattened pod, wingless seeds, and 
_a capitate or bilobed stigma. There are about a dozen species, 
chiefly from the Mediterranean, and extending to the Hima- 
layas and North America. Name from yepos, the hand, and 
avOos, a flower; application uncertain.
