This member of the Cucurbitaceae family was given this name by Edward Lee Green in 1895. It is found in Sonora, Mexico where it grows in well-drained grit, using quite some water in the growing-period. Doesn't need much sun, keep the caudex in the shade. It can grow to 60 centimetres in diameter, vines up to three meters. The flower is yellow, the berries red, and it's possible to make cuttings. It is dioecious.
