Abstract


The morphology and vascular anatomy of the flower of Galtonia viridiflora I. Verd. (Ornithogaloideae, Hyacinthaceae) were studied. Each of tepals, and each stamen is supplied by single vascular bundle. Vascular system of the gynoecium is presented by three dorsal and six lateral veins, as well by ventral complex which forms ventral carpelar bundles. Accordingly to W. Leinfellner concept of the gynoecium vertical zonality, it was established that this gynoecium consists of the following structural zones: synascidiate, symplicate, hemisymplicate and asymplicate. The septal nectary has three separated cavities located on the septal radiuses, which extend from the ovary base to the roof, and opens outward at the style base. The nectary of G. viridiflora has a zone of distinct nectary with congenitally closed nectary cavities in the synascidiate and symplicate zones, and common nectary zone with postgenitally closed central part in the hemisymplicate zone. Nectary deferent channels are located at the level of asymplicate zone of the gynoecium. Therefore, the gynoecium of G. viridiflora can be determined as syncarpous in a broad sense with common septal nectary sensu Odintsova.
