Lagochilus ketmentubensis (Lamiaceae) – новый вид из Кыргызстана

The paper provides a description of a new species of Lagochilus subsect. Triangulolobi Zuckerw. (Lamiaceae) from Kyrgyzstan. Lagochilus ketmentubensis sp. nov. belongs to the affinity of L. platyacanthus Rupr. Last one species has distribution area from the northern-west China and Kazakhstan to northern Pamir-Alai (Alai Mt. Ridge and Alai valley), while L. ketmentubensis is distributed in the foothills around Ketmen-Tube depression (Western Tian Shan). A new species differs from morphological similar L. platyacanthus primarily by ovate or broadly ovate (vs. subulate) bracts. This character is firstly recorded in the genus Lagochilus but it was previously used for interspecies differentiation in other genera of the Labiatae family. The discovery of one more local endemic, closely related to a fairly widespread species, along with the previously described species Scutellaria botbaevae Lazkov and Salvia vvedenskii Nikitina, confirms the status of this territory as a distinct floristic district.
