and considerably so towards the apex, which is less deeply notched 
on account of the wings not being so much developed. ‘The surface 
of the pods is glabrous, with but a slight trace of the vesicular 
papillae which form so conspicuous a feature in those of L. cam- 
pestre. The style is a little longer than in that species, and projects 
conspicuously beyond the notch. The seeds are shorter and more 
regularly oblong-ovoid. ‘The stem and pedicels are hispid, with 
short spreading hairs. ‘The leaves vary from being downy to quite 
glabrous, in which latter case it is probably the form distinguished 
as L. heterophyllum (Bentham), of which, however, I have seen no 
authentic specimens.

Rootstock slender, woody. Stems sub-solitary, flexuous, ascend- 
ing. Radical leaves obovate, stalked. Stem leaves sessile; the 
lower ones obovate, slightly sagittate at the base; upper ones 
oblong-oval, ovate or lanceolate, amplexicaul, with very large 
converging auricles. Petals more than twice as long as the sepals. 
Stamens 6. Pod rather broader than long, reniform - deltoid, 
constricted between the valves, which have no wing; style more 
than half as long as the pod. Seeds obovate-ovoid, coarsely 
punctured.
