Gibbaeum dispar is a tiny plant up to 20 mm high. In cultivation or in favourable sites in the wild, plants may grow into clumps that are 120 mm wide. Each plant consists of short, woody stems with two unequal leaves at their ends. Leaves are velvety to the touch as they have minute hairs covering them. Flowers are solitary and an intense pink.

Red List status: Vulnerable, as it is restricted to a small area of the Little Karoo near Vanwyksdorp. It is potentially threatened by crop cultivation, mining, roadworks, harvesting for the specialist succulent horticulture trade, and livestock grazing and trampling.

Gibbaeum petrense has sharp-edged, grey-green leaves, forming clumps of various sizes, between 50 and 100 mm wide and 20 to 50 mm tall. Its purple flowers are solitary. It occurs on the northern slopes of the Langeberg, growing in white quartz patches overlaying clay slopes. Its distribution is less than 10 km². In the past, it has lost habitat to road construction and is currently declining due to livestock trampling.

Red List status: Vulnerable.

Gibbaeum schwantesii forms compact clumps, its boat-shaped leaf pairs are very unequal in size, the larger leaf being between 50 and 70 mm. The smaller leaf is only half the size of the larger leaf. Leaves are green to yellowish green and turn red at the edges. Flowers are typically white. This species occurs on the slopes of Langeberg in loamy renosterveld soils. It is known from two populations that occur within 1 km of each other. It is potentially threatened by soil erosion and trampling by livestock.

Red List status: Vulnerable.
