T h e plant here delineated is to be found in ofier grounds
ill various parts of England, nor is it of fo rare occurrence as
we at one time fuppofea, being not uncommon in turnip-fields
in Norfolk and Suffolk, in which counties it fometimes occurs
as a weed in gardens. Our wild fpecimen came from Norwich.
It is an annual, flowering about July.
The Item is ereft, varying greatly in fize, as well as number
of branches, according to the richnefs of the foil, ftraight,
leafy, angular, covered with fmall clofe-preffed briftles. Leaves
lanceolate, either quite entire, or furnifhed with a few diftant
teeth, roughifli, with fmall, depreffed, whitifli, often forked
or three-cleft, briftles, which are alfo found on the ftalks and
pods. Flowers numerous, fmall, yellow, with a yellowifti
ereft calyx. The partial flower-ftalks become horizontal as
the fruit increafes, but the pods themfelves Hand eredl, and
are fquare, tipped with a minute feffile ftigma.
Mr. Hudfon firft adopted this plant from Ray, and was led
by Bauhin’s fynonym to refer it, rightly, to the E . cheiran-
tboides of Linnaeus. When he himfelf gathered what we
know, by authentic fpecimens, to be the fame, he erroneoufly
took it for Cheiranthus eryfimoides, and thus in his 2d edition
has one plant under two names.—The Englilh name arofe
from its entering into that nonfenfical hodge-podge called
Tberiaca or Venice Treacle.
