Myosotis kazakhstanica (Boraginaceae), a new species from Kazakhstan
Abstract
Myosotis kazakhstanica O. D. Nikif. is described as a new species endemic to the Kazakhskiy Melkosopochnik. The novelty is related to M. baltica Sam. ex Lindm. and M. caespitosa Schultz (section Myosotis) but differs from them in pubescence of leaves and calyx, form of inflorescence, shape and size of the calyx and erems; key diagnostic characters are illustrated. Myosotis kazakhstanica grows in places of groundwater wedging out, in birch-aspen clumps, near clean freshened springs, at the foot of mountains on relatively well-moistened fine-grained sites among granite slabs. In addition, the parallel variability of the inflorescence and pubescence of leaves in annual species of two closely related genera – Myosotis and Strophiostoma Turcz. – was revealed.
