Alluaudia comosa is a rare species of flowering plant. It belongs to the family Didiereaceae, subfamily Didiereoideae, which is found only in the coastal area of SW Madagascar.[1] Didierea comosa Drake is a synonym.[2] It is listed as "vulnerable" on the IUCN Red List of Threatened Species.[3]
Description
Alluaudia comosa has a distinctive, easily recognized silhouette with a short trunk and dense branches that stop in a flat crown.[4] This is a deciduous shrub to small tree 2-6 (-10) metres tall[4] that is woody, semi-succulent and spiny, with spines set singly.[1] Spines are grey and 1.5-3.5 cm long.[4]
Leaves are developed mostly in pairs, set on a short stalk (petiole), dying off at the beginning of the dry season.[1] They are rounded (10–22 mm X 10 mm) and fleshy.[4]
Flowers
Flowers are produced on a reduced inflorescence in Alluaudia comosa; only the end flower develops, and is set on a very short axis. Flowers are dioecious (male and female flowers on separate plants).[1]
Habitat
This species grows on limestone in dry forests or coastal shrubland.[3]
