Xerosicyos is a flowering plant genus of the family Cucurbitaceae. Its name comes from Greek xeros (meaning "dry") and sicyos ("cucumber"). There are six species, ^[1] all endemic to Madagascar. ^[2]

Species

Six species are accepted. ^[1]

• Xerosicyos danguyi Humbert is a large liana with thick stems and round, gray succulent leaves. It is common in cultivation and often called the "silver dollar" vine. ^[3]
• Xerosicyos decaryi Guillaumin & Keraudren
• Xerosicyos hirtellus (Humbert) H.Schaef. & S.S.Renner
• Xerosicyos perrieri Humbert is also a liana with thinner stems and smaller, ovate green succulent leaves. ^{[4] [5]}
• Xerosicyos pubescens Keraudren 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. ^[6]
• Xerosicyos tripartitus (Humbert) H.Schaef. & S.S.Renner
