Delonix pumila

Delonix pumila is a small, dwarfed tree growing up to 3 meters tall. It is a slow-growing plant which loses its leaves during the dry season and develops a swollen caudiciform trunk as it matures. Its flowers open at night, and have white petals, including an upper petal with a narrow tubular nectariferous claw, and long dark stamens.

This species is limited to a small area around Toliara in southwestern Madagascar. It has been found near 'La Table' hill approximately 25 km east of Toliara, along the escarpment edge of the adjacent Mahafaly Plateau, and in an area south of Onilahy River. Its estimated extent of occurrence (EOO) is 311 km2 and the area of occupancy (AOO) is 93 km2. It inhabits spiny thicket and coastal bushland with succulent species of Euphorbia on limestone rock, from sea level up to 160 meters elevation.
