This species occurs in South Africa.
The deciduos leaves are a light green, velvet texture with wavy edges occuring only near the top of the plant and on the tips of its few branches. The trunk is similar to lamerii but has far more spines and the color is more of a brownish green. Spines are in clusters of three where the leaves were located. This species is known for its unwillingness to adapt to the seasons of the Northern hemisphere, growing in the winter and resting in the summer. The flowers are a dull yellow with a purple tint in the center. Flowering is not common but will occur infrequently. The flowers are formed in a bunch near the tops of the plant and branches. Namaquanum should be given full light and water during the winter months and less water in the resting periods.
