(b) Subsp. crinita (Mabille) W. Greuter , Boissiera 13: 108 (1967)

( K. elatine subsp. sieberi (Reichenb.) Hayek , Linaria sieberi Reichenb. , L. crinita Mabille ):

Main branches ascending, rela­ tively stout, densely hairy, usually with several short, patent, flowering secondary branches. Leaves more or less obtuse, the lower ovate to indistinctly hastate, the middle and upper usually hastate. Pedicels hairy throughout, 2|-3 times as long as the calyx in flower, not more than 2 cm in fruit. Corolla up to 15 mm. S. Europe.

Some plants from Spain and Portugal, in other characters referable to subsp. (b), have long, subglabrous pedicels, as in subsp. (a).

K. caucasica (Mussin ex Sprengel) Kuprian. in Schischkin & Bobrov, Fl. U RSS 22: 178 (1955), which occurs in S. Ukraine, should probably be regarded as an extreme variant of (b) in which even the middle leaves are scarcely hastate.
