This paper presents the results of morphological and anatomical studies of Helleborus caucasicus и Helleborus abсhasicus, introduced in Sukhumi Botanical Garden Institute of Botany of Abkhazia. Signs generative sphere species Helleborus vary significantly and independently of the species belonging to very low, low, less the average level of volatility. The upper and lower epidermis is represented by polygonal cells. Stomata are present on both sides, but more abundant below. Over large veins elongated epidermal cells - rectangular, with beaded wall thickening. Stomatal apparatus anomotsitnogo type. Across the surfaces are clavate glandular hairs on unicellular stalk, with yellow contents. The shape of pollen in both species rounded surface exine rough, trehborozdnaya. A cross section of the seed-layer stand testa as a dark-brown stripes and endosperm. Over the entire surface on the testa found unicellular hairs. Studies were carried out using conventional techniques.
