Morphological structure of inflorescences of Agastache breviflora (A. Gray) Epling, A. rugosa (Fisch. & C.A. Mey.) Kuntze, and A. rupestris (Greene) Standl. (family Lamiaceae) ex situ

Abstract

Galina O. Rudik

The results of comparative analysis of morphological structure of inflorescences Agastache breviflora, A. rugosa, and A. rupestris introduced in the O.V. Fomin Botanical Garden are represented. It has been established that the common morphological characteristics for inflorescences of these plants are: the type of inflorescence (thyrs), its location on the shoot (terminal), type of the growth of main and lateral axes (monopodial growth of the main axis and sympodial growth of lateral axes on which are formed the partial inflorescences – cymoids), the structure of the partial inflorescences (system of dichasia). Differences are determined by the linear dimensions of inflorescences, quantity and size of flowers in partial inflorescences, orientation of the main axis and flowers in space, presence or absence of bracts and bracteoles.
