CRUCIFER. 167 
Var. 8, hispida. 
Leaves clothed with forked and trifurcate hairs all over. 
Very rare. Var. « by the seaside at Ringville, Connemara, 
Treland. Var. @ near Tenby, Pembrokeshire, and probably in other 
places in the West of England but overlooked on account of its 
resemblance to A. sagittata. 
England, Ireland. Biennial. Spring, Summer. 
Rootstock producing rosettes of oval or elliptical leaves, atte- 
nuated at the base into a footstalk so as to become oblanceolate, 
from which one or more stems 3 to 9 inches high are produced. 
Stem densely clothed with leaves throughout, the leaves becoming 
narrower and broader at their base in proportion as they are placed 
higher on the stem, but even the very uppermost have always the 
rudiments of a footstalk. Leaves all entire or very slightly toothed. 
Flowers $ inch across, white. Pedicels + inch long. Pods 1 to 
1} inch long by +5 inch broad. Seeds about 3!5 inch long, 
broadly oval, rounded at each end, finely punctured (under a lens), 
distinctly winged all round. 
Arabis ciliata of Continental authors is A. arcuata, ‘* Shuttle- 
worth” (Godet, Flore de Jure, p. 38), and seems to be another 
sub-species of A. hirsuta quite distinct from the present, having 
the leaves less closely placed on the stem, which is arched at the 
top before the pods are ripe, and the seeds are without a wing.

inflorescence. Uppermost stem leaves truncate, slightly cordate 
or sagittate at the base, semi-amplexicaul. Pods four to nine 
times as long as the pedicels, and at the broadest part not twice 
the breadth of the pedicels. Seeds twice as long as broad, truncate 
at the base, rounded at the apex.
