Morphological features of leaves in the genus Echinacea Moench under introduction

The comparative morphological characteristics of leaves of the genus Echinacea representatives (E. pallida (Nutt.) Nutt and E. tennesseensis (Beadle) Small) introduced in the O.V. Fomin Botanical Garden are given. The established morphological features allow determining the adaptive capacities of species of the genus Echinacea ex situ. Despite of taxonomical belonging, the leaves of basal formation are most developed. Studied features could be applied during the implementation of these plants in pharmaceutical industry. Also these features could be useful during further investigations of adaptive possibilities of Echinacea species in ex situ conditions
