Barkeria scandens and B. whartoniana are endangered, endemic taxa from Mexico. They are epiphytes adapted to dry habitats. Since these plants are xerophytic, their flowers were investigated for structural adaptations to nectar secretion. The flowers

The subject of research were morphology and ultrastructure of floral nectaries of nine species of Vicia. The differences in their size and morphological structure were shown. Small, almost flat nectaries appeared in flowers of Vicia tetrasperma and V
