- Аннотация: The present study reports the inflorescence ontogeny and morphology in tribe Fabeae (Fabaceae) addressing the evolutionary trends of selected inflorescence features in clade Lathyrus-Pisum-Vavilovia. In all three mentioned genera, the whole inflorescence in annual taxa comprises an open shoot bearing frondose leaves subtended by simple racemes. This shoot exhibits a pendulum symmetry which results from skewed position of leaves initiating at shoot apex. During floral initiation in a model species, i.e. Vicia cracca, numerous flowers are produced on these racemes but later most of them degrade and only a small portion (< 4%) of previously initiated flowers result in production of mature fruits. This many-flowered state is derived from a single- or few-flowered one typical for the most basal representatives of this clade. The single-flowered state strongly correlates with annual life form and arises repeatedly during evolution of tribe Fabeae. The adaptive values of different inflorescence types are discussed.
