Vines perennial. Stems trailing, 50–150 cm, pustulate-scabrous to pustulate-hispid and sparsely hirsute with deflexed hairs; roots fleshy to ± woody, tuberous; tendrils usually unbranched, rarely 2-branched. Leaf blades elongate-ovate, 1–6(–11) cm, 3–5(–7)-lobed, lobes pinnately shallowly lobed or sinuate, margins serrate to dentate, surfaces pustulate-scabrous.

Discussion
Citrullus colocynthis is a traditional food plant in Africa, where it is grown particularly for its edible seeds, which are bitter but nutty-flavored, rich in fat and protein, and eaten whole or used as an oilseed. It has also been a standard cathartic remedy, mostly in combination with other cathartics.
Three main haplotypes within colocynth have been identified via molecular data (F. Dane and P. Lang 2004; Dane and J. Liu 2007; A. Levi and C. E. Thomas 2005).
Colocynth rarely is encountered outside of cultivation. It has been reported as a weed in Texas peanut fields (G. L. Nesom 2011); in Massachusetts, it has been sporadically collected since 1878; in California, it has been collected on a pond dike in an area of cotton fields in Kern County.
