A new, highly endangered and restricted-range species of Parrya sect. Pseudoclausia, comb. nov. (Brassicaceae) from Western Tian Shan, Uzbekistan

Researchers have identified Parrya tojibaevii, a new species of flowering plant in the Brassicaceae family, endemic to a highly disturbed area around the confluence of the Chatkal River and Charvak Reservoir in Western Tian Shan, Uzbekistan. This species is morphologically distinct from related taxa, such as P. gracillima and P. mollissima, and belongs to the newly recognized Parrya sect. Pseudoclausia. The discovery highlights the species' critically endangered status due to its restricted range, which is under growing threat from infrastructure development, recreation, and grazing. The study combines morphological analysis with field observations to document this novel taxon, emphasizing the urgency of conservation efforts for this unique and vulnerable plant.
