The genus Kuschakewiczia, Regel and Smirnov [1], was described including only one species, K. turkestanica. Later it was joint with the genus Solenanthus, although there are characters (corolla having narrow long lobes, filaments inserted on the corolla margin, low gynobasis, small scar on nutlets after disconnecting without any strip of tissue, reduced number of nutlets in the ripe fruit, etc.) which distinguish the two genera sufficiently. Palynological data, although not significantly different, support its separate positions on the discrete generic level.
