Sus-Srecres ITI.—Draba inflata. Watson, 
Puate CXXXIV. Fic. 3.* 
D. verna, var. 3, Hook. & Arn. Brit. Fl. ed. viii. p. 30. 
Pods oval- ovoid, about twice as long as broad, not com- 
pressed, narrowed in a regular curve towards the base and the 
apex ; valves convex. Seeds 20 to 40 in each cell of the pod. 
On rocks and rocky débris on Stuich-an-Lochan, close to Ben 
Lawers, Perthshire, on the north side of Loch-na-Gat. Mr. Baker 
mentions a plant near Thirsk which he believes to be the same as 
the Ben Lawers plant. 
England? Scotiand. Annual or Biennial. Summer (in the 
Perthshire locality). 
The remarkably inflated pods of this form distinguish it from 
the two preceding. It approaches nearest to the Erophila 
glabrescens of Jordan, but the pods are smaller, being about } inch 
long, as well as swollen, the petals less deeply bifid, and the seeds 
paler and yellowish brown. The stems are from 38 to 6 inches high, 
and nearly glabrous except towards the base. 
Seeds of this plant, brought from Ben Lawers in 1851, were 
sown in Mr. Watson’s garden, and the plant has been there main- 
tained in cultivation to the present time without showing any 
alteration in the shape of the pods, in this agreeing with the 
observations of Sir William Hooker.

Stem branched, with rather distant leaves, pubescent except at 
the summit. Radical leaves obovate or oblanceolate; stem leaves 
ovate, amplexicaul; all sharply toothed (especially those on the 
stem) and hairy. Petals entire, rounded at the apex. Raceme 
elongating much after flowering. Pedicels spreading, nearly twice 
as long as the pods. Pods elliptical, compressed, not twisted. 
Style, almost none.
