Alluaudia montagnacii is a rare species of flowering plant in the family Didiereaceae.
Description

Alluaudia montagnacii can reach a height of 2.4–6 metres (7 ft 10 in – 19 ft 8 in). The tall columnar central trunk sprouts strong vertical branches. Stem and branches have symmetrically arranged leaves, about 1.5 cm long, and black-tipped thorns, 2–2.5 cm long. Leaves are deciduous in the long dry season. Photosynthesis is carried on by the stems. This plant is well adapted to live where water is a limiting environmental factor. The flowers are small, green or yellow.
Distribution and habitat
Alluaudia montagnacii is endemic to the Mahafaly Plateau of southwestern Madagascar.[1] It grows in small arid and subarid areas on a narrow belt of the coast. It is part of the Madagascar spiny forests, where it forms a specific plant community with species such as Cedrelopsis grevei and Ficus marmorata.[1]
