ABSTRACT: Central Asia is one of the main centers of origin of
bulbous geophytes, including the family Amaryllidaceae Juss. The anatomical
features of many endemic, red-book bulbous geophytes are still poorly
understood. The article presents the results of a structural study of the
inflated part of
the stem (fistular), stem and pedicels of an endemic A. praemixtum species grow in
two different environmental conditions in the Aktau mountain Nurata Range (Uzbekistan, Province Navoi) and
in the conditions of introduction in the Tashkent Botanical Garden (Uzbekistan,
Tashkent city). Diagnostic signs of vegetative organs were revealed and various
combinations of xeromorphic and mesomorphic signs were determined. Comparative
anatomical study of vegetative organs of A.
praemixtum is of great theoretical
and practical importance in relation to taxonomy and ecology.
