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.
