19b. Corydalis sibirica Group

北紫堇类群 bei zi jin lei qun

Herbs, annual (rarely biennial) with small taproots (in Corydalis pinnatibracteata root robust). Flowers small; dorsal crests of inner petals prominently protruding. Stigma with (2-)4 ± stipitate apical papillae, flanked by a sessile double (geminate) papilla on each side close to apex; base without papillae.

Nine species: China, Mongolia, Russia (Siberia); nine species (seven endemic) in China.

Corydalis pinnatibracteata, C. pseudosibirica, C. tongolensis, and C. yui (and possibly other species) are notable for the coexistence of muricate and smooth seeds within a population.
