We only have one record so far of this species, near Guineafowl Dam. It is widespread across Africa and Asia. In South Africa it is more prolific in the Highveld and across the Karoo, whereas G. africana is common in the Central Lowveld.

Identification

Growth: Sprawling to low-climbing annual herb (10–70 cm long) with pinkish or red-tinged branching stems.
Leaves: Fleshy, narrow, light green leaves held in opposite pairs with smooth edges and short stalks.
Flowers: Small greenish-white, pink, or purplish flowers (2–3 mm) borne in tight clusters along the stems.
Fruit: Cluster of five tiny, rounded dry nutlets covered in fine raised bumps or warts.
Texture: Stems and fleshy foliage are completely smooth, hairless, and studded with tiny white crystal specks.

Did You Know?

While the fleshy leaves and young shoots of Gisekia pharnaceoides are regularly boiled down as a survival pot-herb across dry African and Asian savannas, raw and fruiting plants carry high concentrations of oxalates and bitter saponins toxic to browsing livestock. This potent internal chemistry earned it historical fame in both Ayurvedic and African folk medicine as an aggressive "taenicide" - where freshly crushed preparations were administered on an empty stomach specifically to stun and expel tapeworms (Taenia) from the gut.
