Characteristics

Tubers stalked, borne laterally on the main roots, about 30 cm long, fusiform. Stems erect or scrambling, slightly zigzagging, woody, smooth or slightly ridged, grey-green, glabrous. Branches solitary, almost always grooved, much-branched, similar to the stems. Cladodes fascicled, three-angled, rigid, mucronate, 15-20 mm long or sometimes only 1 cm or less, linear. Spines present on all stems and branches, pungent, slightly recurved, browner than the stems and branches; the rest of the leaf not conspicuous. Peduncles 1-4-nate, with or without spines, up to 10 cm long, articulated near the centre; the proximal half greatly thickened. Perianth segments oblong to obovate, the outer whorl narrower, 2.5-4 mm long, white, reflexed near the centre of each segment. Stamens nearly as long as the perianth segments. Style slightly less than 1 mm long, divided for about half its length; ovary about 1 mm long. Berry smooth, 1-seeded, red; perianth not persistent.
