Populations probably referable to the hybrid 16 x 34 are rather frequent in Britain, sometimes occurring independently of the presumed parents; these plants have more flexuous stems, more acutely toothed leaves and sometimes slightly larger flowers than 34.

Specimens from Iceland often approach 28 in their hairy, broader leaves.

E. heslop-harrisonii Pugsley , Naturalist (Leeds) 1945: 43 (1945), from N. Scotland, is like 34 but has usually flexuous stems, cau­ line internodes not more than 2(-3) times as long as the leaves, leaves not purple beneath, the cauline with not more than 4 pairs of teeth, the lower floral broadly ovate to frullate, and the cap­ sules (4-5-)5 -5-7 mm.
