Euphorbia ambovombensis

A dwarf succulent Euphorbia with a thickened, tuberous root and short leafy stems, known only from the dry south of Madagascar around Ambovombe. It wants warmth year round, strong but not scorching light, and a fast-draining mineral mix with a drier, cooler rest in the southern winter.

Where it grows wild

Dry spiny bush and dry forest on sandy, well-drained ground in far southern Madagascar, where small plants sit among and under shrubs. Detail beyond the original description and the IUCN habitat class is thin; conditions here are built from the measured climate and what is known of dwarf Malagasy euphorbias.

The two recorded sites lie at about 130–170 m, near the coast.
