The morphological characteristics of seven species belong to Asclepias L. and Vincetoxicum Wolf (Apocynaceae) are presented. The differences can be used as additional diagnostic criteria for species identification. The most important diagnostic value of the genus is a character of hem. The hem of Asclepias species surrounds the seeds reaching 1/3–1/4 of its width. The Vincetoxicum species have hem 8–18 times narrower than the seed. Species differ in the surface character, hem configuration on the apex and at the base of the seed and in the shape of raphe.
