CRUCIFERAE (MUSTARD FAMILY) 197 
Sheep are fond of Winter Cress and cattle feed on it with as 
greedy an appetite as on rape or turnips or other cultivated cruci- 
fers; for this reason its planting as forage has been advocated, but 
its weedy habit of never “staying put” should be considered. 
Means of control 
Spudding or hoe-cutting the rosettes from the roots in the first 
year of growth, and closely cutting the flowering stalks while they 
are in first bloom. 
SCURVY GRASS 
Barbaréa vérna, Asch. 
(Barbaréa précox, Sm.) 
Introduced. Perennial. Propagates by seeds. 
Time of bloom: April to June. 
Seed-time: June to August. 
Range: Massachusetts to Virginia, and westward to Missouri. 
Habitat: Fields, meadows, and waste places. 
Often cultivated for winter salads, frequently escaping and now 
thoroughly naturalized as a weed. A more slender plant than the 
preceding species, its root-leaves more finely divided, having five 
to eight pairs of lateral segments. Flowers smaller and a paler 
yellow. Pods much longer, sharply four-sided, slightly compressed 
on short and very thick pedicels. Seeds smaller, more numerous, 
brown and flattened. 
Means of control the same as for Winter Cress. The smooth, 
glossy surface of these two Mustards renders them impervious to 
injury from sprays. 
BULBOUS CRESS 
Cardémine bulbésa, B.S.P. 
Other English names: Bitter Cress, Spring Cress. 
Native. Perennial. Propagates by seeds and by tuber-bearing 
rootstocks. 
Time of bloom: ApH ic June. 
Seed-time: May to J 
Range: Nova Scotia to Minnesota, southward to Florida and 
Texas. 
Habitat: Wet meadows, swamps, sides of streams, and ditches.
