Flower: corolla lobes +- spreading to erect-incurved, ring of tissue at corolla base present or not; filament column appendages +- 0 or free from each other, fused to ring of tissue at corolla base or not, +- spheric, attached to base of filament column, without projections, hollow (possibly due to complete fusion of margins), anthers fused into anther head around and fused to pistil head, pollen in pollinia; pistil head flat or, if +- conic, 2-lobed or not; nectaries in stigmatic chambers.

Etymology: (Greek: fleshy crown or wreath, from sac-like filament column appendages of some species) Note: Our species treated as Cynanchum, Sarcostemma in TJM (1993), both shown to be polyphyletic in previous, broader circumscriptions (Liede & Täuber 2000, 2002).
