The subfamily Asclepiadoideae is represented by 16 taxa belonging
to 5 genera (Araujia, Cionura, Cynanchum,
Gomphocarpus and Vincetoxicum) in Türkiye. It is known that the floral morphology supplies
an important contribution to delimitation of the Apocynaceae taxa. Thus, in
this study, the floral characteristics of the Turkish Asclepiadoideae members stored
at both Herbarium of Recep Tayyip Erdoğan University, Department of Biology and
Herbarium of Istanbul University, Faculty of Pharmacy were examined in detail using
a stereomicroscope. Our results showed that all
the examined taxa are characterized with the inflorescence including terminal
or axillary cymes, rarely solitary flowers, actinomorphic, bisexual,
pentamerous flowers with rotate or campanulate corolla, coralline or gynostegial, free or partly fused corona
segments, and a typical gynostegium composed of unlobed or bifid stigma. The present research also
pointed out that the length of pedicel, sepal, petal and pistil, the pubescence,
color and type of the corolla, the origin, type and shape of the corona, and the shape of the stigma are
the most important floral traits at the species level within the Turkish
Asclepiadoideae.
Key
words: Anatolia, Asclepiadoideae, corona, flower morphology.
