Orbea decaisneana is a succulent subshrub and grows primarily in the desert or dry shrubland biome. It is native to north Africa; Algeria, Burkina Faso, Mali, Mauritania, Morocco, Niger, Senegal, and Sudan/South Sudan.[1]
The plants found in Morocco have been called Caralluma decaisneana subsp. hesperidum but this subspecies is not recognised by POWO.[1] Some botanists argue that they are sufficiently different to be their own subspecies or even species - the flowers even have very different smells.[2]
Stems erect, more or less cylindrical, slender, apically tapering, whitish green, marbled or spotted with brown, 10 - 40 × 1.5 cm diameter, 3- to 6-ribbed, sides conspicuously furrowed; tubercles 0.7 - 1.5 cm, strong, conical-subulate, horizontal to ascending. Inflorescence with 1 - 3 more or less erect flowers; peduncle cushion-like, 1- to 20-flowered, sometimes with 1 mm long filiform bract; pedicel 1 - 5mm, more or less conical; sepals 4 - 5 mm. Corolla dark purple or reddish-brown, 1.5 - 2.5 cm diameter, flat, tube 4 (-6) × 8 mm diameter, campanulate, embracing the corona.[3]
The species complex is widely spread and variable.[3]
