Flowers pale yellow, veined, # inch across, in a very short raceme, 
which lengthens as the fruit ripens. Pedicels about as long as the 
calyx in flower, shorter than the beak of the pod in fruit. Pods 
slightly beaded, 2 to 25 inches in length including the beak, which 
is from } to # inch, and is of the same thickness as the pod at 
its base where it contains seeds, but terminates in a subulate point 
where it is empty. Seeds oblong, dark brown, finely punctured. 
Whole plant very glaucous and glabrous; the stem sometimes 
with a few hairs.

Channel Islands. Perennial. Summer. 
Extremely like the preceding sub-species, but taller; the stem 
being from 1 to 3 feet high. The plant is less glaucous and more 
hispid ; and the leaves, instead of being arranged in a rosette, are 
scattered on the stem. 
Sus-Genvus [II.—DIPLOTAXIS. D.C. 
Sepals slightly spreading, often hairy. Seeds ovoid-compressed, 
arranged in a double row down each cell of the pod. 
Diplotaxis, from didooe (diploos) double, and raéte (taxis), a series ; because of the 
seeds being disposed in two rows in each cell.
