Densely branched bushes of this variety, up to a meter tall and to more than a meter in diameter, occur from Fianarantsoa in the central highlands of Madagascar to Tulear in the southwest and Beloha in the south; in the highlands they are locally abundant.

The plants are variable in the size of the stems and leaves as well as the flowers.
On average the leaves are 30 x 4 cm, grey-green with reddish tinge, without markings.
The inflorescence is to 50 cm long, undivided or with 2-4 branches; the flowers are coral-red with pale red tips.
