This species occurs in South Africa.
This Species is very similar to the succulentum and without flowers it is hard to differentiate. The leaves are slightly more narrow than those of the succulentum and tend to curl on the edges. The spines are fairly short in comparison. The trunk is mostly located under ground but the upper portion has a light green tint. The flowers are bell shaped with white petals and a purple tint in the throat. Bispinosum should be given full light and plenty of water during the warmer months for vigorous growth and plentiful flowering. Flowers will appear in early spring and last most of the summer or longer in good conditions. Flowers set individually but the branches may support an abundance.
