Asclepiadoideae

Mountain kambroo Fockea edulis, copyright Ann.

Belongs within: Euapocynoidina.
Contains: Asclepiadeae, Marsdenieae, Ceropegieae.

The Asclepiadoideae are a group of milkweeds possessing clasping translators with two pollinia per translator. As the Asclepiadoidina, they were defined by Sennblad & Bremer (2002) to represent the largest clade including Fockea and Asclepias but not Secamoneae.

Members of this clade have been divided between four tribes, the Fockeeae, Ceropegieae, Marsdenieae and Asclepiadeae. The Fockeeae include two genera found in sub-Saharan Africa and the Arabian Peninsula in which the pollinia are sessile. Cibirhiza has flowers with spreading lobes on the outer corona, a distinct flat fused portion of the corolla extending beyond the corona, and almost obsolete anther appendages. Fockea has a tubular outer corona, the corolla divided as far as the corolla, and long anther appendages exceeding the stylar head (Thulin et al. 2008).
