Alluaudia is a genus of flowering plants in the family Didiereaceae. There are six species, all endemic to Madagascar.[1]
Most occur in the southwestern subarid forest-thicket vegetation of the island.[2]
Spines are arranged around the leaves as a defense against herbivores. The spines are several meters above the ground, and probably evolved in response to herbivory by now-extinct lemurs, such as Hadropithecus. Several lemur species living today feed heavily on Alluaudia, such as the ring-tailed lemur (Lemur catta) and the white-footed sportive lemur (Lepilemur leucopus).[3]
