The genus Xerosicyos belongs to the Cucurbitaceae family of flowering plants. Greek words for "dry" and "cucumber" were combined to create its name. The three species are all endemic to Madagascar. The incredible liana Xerosicyos danguyi has robust stems and rounded, gray succulent leaves. It is widely cultivated and is frequently referred to as the "silver dollar" vine. Another liana with smaller, ovate-shaped succulent leaves and thinner stems is called Xerosicyos perrieri. The new species, Xerosicyos pubescens, is totally distinct from the earlier one. Deciduous vines sprout from a large caudex that it produces. The semi-succulent, lobed leaves die back throughout the dry season and during protracted droughts.
