(d) Subsp. spathulata (A. F. Lang) Walters , Feddes Repert. 69: 57 (1964)

( E. spathulata A. F. Lang ):

Stems usually several, up to 10 cm in fruit. Leaves obovate-spathulate, more or less densely clothed with short branched hairs. Sepals c. 1 mm; petals c. 2 mm; stamens shorter than stigma. Silicula broadly obovate or suborbicular; fruiting pedicels 3-18 mm. Distribution like that o f 1 (a) but apparentlypreferring more calcareous substrata.

E. duplex Winge , Compt. Rend. Trav. Lab. Carlsb. (Sér. Physiol.) 23: 71 (1940), with several stems up to 18 cm, more or less coarsely toothed leaves, and flat silicula, probably belongs here. It has 2« =30-40.

The other apparently widespread taxon described by Winge, E. quadruplex Winge, loc. cit. (1940), is a more robust plant than E. duplex, with a single stem. The leaves are narrowly cuneate and usually toothed. It has 2n = 52-64. Such plants would seem to fall between 1 (a) and 1 (d).
