Vincetoxicum anatolicum (Apocynaceae), a new species from eastern Turkey, is described and illustrated. Additionally, a revised key for Turkish Vincetoxicum is provided and the seed micromorphology and palynological properties of the new species is described for the first time. The new species is morphologically similar to V. fuscatum and V. parvif...

... 2017). According to Browicz (1978) and Güven (2017) (Güven 2017). Vincetoxicum anatolicum is morphologically related to V. fuscatum and V. parviflorum based on some phenetic characteristics such as habitus and flower color. However, V. parviflorum exhibits a quite different corona structure composed of free, succulent, oblong corona segments (Fig. 3c) and can easily be differentiated from the remaining two species. The habitus of V. anatolicum and V. fuscatum are similar, but some floral characteristics such as peduncle length, flower color and corona structure contribute significantly to the separation of these two taxa (Table ...

... fuscatum, characterized by sessile or rarely short pedunculate (5-7 mm) inflorescences, brown, glabrous or crispedpubescent corolla, and semi-circular corona segments partly fused with intermediate teeth (Fig. 3b), differs from V. anatolicum which has 8-12 mm long peduncles, yellow to light brown corolla with crisped hairs on the inner surface, and ovate corona segments partly fused with intermediate teeth (Fig. 3a). The peduncle length, corolla color and pubescence, and corona shape are among the widely used diagnostic characters to identify ...

The peduncle length, corolla color and pubescence, and corona shape are among the widely used diagnostic characters to identify species within the genus Vincetoxicum in The Flora of Turkey (Browicz 1978), as well as in many other floras (Pobedimova 1952, Grossheim 1967, Rechinger 1970, Markgraf 1972, Ali 1983.
