the tip, with short triangular or oblong lobes pointing towards

leaves applied to stem, oblong or oblong-lanceolate, toothed or 
entire, the upper ones more or less semi-amplexicaul. Petals nar- 
rowly oblanceolate, about thrice as long as the sepals, erect. Pods 
erect, five to ten times as long as the pedicels; valves 1-nerved ; 
style scarcely perceptible. Seeds in one row, oval or oblong, much 
compressed, narrowly winged all round (in the British forms), with 
the wing broadest at the apex. 
Hairy Wall Cress, Hairy Tower Mustard. 
French, Arabette & Velue.

its dry and exposed situations on walls and calcareous rocks. In cultivation it loses 
much of its hairiness, and grows into a tall and elegant plant.
