Genus of flowering plants
Xerosicyos is a flowering plant genus of the family Cucurbitaceae. Its name comes from Greek "xeros" (meaning "dry") and "sicyos" ("cucumber"). There are three species, all endemic to Madagascar. 
Species.
"Xerosicyos danguyi" is a large liana with thick stems and round, gray succulent leaves. It is common in cultivation and often called the "silver dollar" vine. 
"Xerosicyos perrieri" is also a liana with thinner stems and smaller, ovate green succulent leaves. 
"Xerosicyos pubescens" is entirely different from the previous species. It forms a large caudex from which deciduous vines emerge. The leaves are lobed and semi-succulent and die back in the dry season and during prolonged periods of drought.
