The finger-like, succulent leaves of Antegibbaeum fissoides grow in decussate pairs from the gap between the previous pair, the leaves not widening to their tips but tending to curve.

The sometimes slightly unequal leaf-pairs are joined at the base, flat or slightly convex on the inside or upper surface and roundly keeled on the outside, the tips blunt. The smooth, waxy leaf surfaces are grey-green, often yellow-green initially, reddish in winter and sometimes blackened by fungal growth.

The leaves become up to 10 cm long (Vlok and Schutte-Vlok, 2015; Smith, et al, 1998; iNaturalist; http://www.llifle.com).
