Morphological adaptation of Nepeta pamirensis Franch. (Lamiaceae) to the conditions of the Pamir Mountains

This study concerns shoot formation and structural and morphological peculiarities of different life forms of Nepeta pamirensis specimens, as well as their morphogenesis and its polyvariety in the conditions of the Pamir Mountains (Tajikistan). Depending on habitat conditions, Nepeta pamirensis specimens form three life forms: herbaceous caudex taproot perennial plants, cushion semishrubs, and aeroxylic semishrubs. For each life form, the phases of morphogenesis were determined and the functional and zonal structures of shoot systems were described.
