19. L. latifolium L. , Sp. Pl. 644 (1753).

Perennial with stoloniferous rhizome; aerial stems 50-130 cm, erect, glabrous, muchbranched above. Leaves coriaceous, the basal and lower cauline up to 30 cm, long-petiolate, ovate, toothed or sometimes pinnatilobed; upper sessile, ovate to lanceolate, entire and often bractlike. Flowers in a large panicle. Sepals c. 0-75 mm, broadly white-margined. Petals up to twice as long as sepals, with rounded-obovate limb. Pedicels 4-5 mm in fruit, silicula 2 x 2 mm, suborbicular, not winged or notched; style very short with a large rounded stigma. 2« = 24. Europe except the north. All except BI Cr Fa Fe Is N o Rs (N). Plants from near the Baltic in Sweden seem to differ in having dark purple sepals and narrower, more toothed upper cauline leaves with a longer acute apex. Specimens seen from Greece and Sicilia have the underside of the leaves densely covered with stellate hairs and are apparently referable to var. velutinum Hayek ex Thell. Further study may indicate that both these variants should be regarded as subspecies.
