New species of Delphinium L. (Ranunculaceae) from the Middle Siberia
A new species named Delphinium tungusense Kurbatsky was described from the Middle Siberia (the basin of the Podkamennaya Tunguska River). New species is distinguished from close species D. mirabile Serg. by longer inflorescence and stalk, shorter leaflets of a perianth (10-13 mm in length, but not 20-25 mm). D. tungusense differs from D. elatum L. in the hairy ovaries and follices, and shorter stem.
