Current State of the Cenopopulation of Cynoglossum viridiflorum Pall. Ex. Lehm. in the Karakalpak Part of the Ustyurt Plateau (Uzbekistan)

Abstract

The current state of a rare medicinal species, the “green-flowered” hound’s tongue (Cynoglossum viridiflorum Pall. ex Lehm.), of Uzbekistan growing in the Karakalpak part of the Ustyurt Plateau, based on the structure of its cenopopulations is examined. New data is reported with respect to the ontogeny and ontogenetic structure of cenotic populations of this rare endemic, and plant communities with its participation are characterized. In the Ustyurt conditions, the vegetation cycle of C. viridiflorum spans approximately eight months from March to October. The studied populations were shown to be normal and full-membered. The left-sided ontogenetic spectrum is characteristic of C. viridiflorum due to the high seed productivity and germination capacity. Altogether, this reflects the biological characteristics of C. viridiflorum and points to a stable state of the species population in the Ustyurt conditions.
