Pachypodium rosulatum, common name elephant's foot plant, belongs to the family Apocynaceae.
From the caudex depart many thorny cylindrical arms, forming a shrub about 1.5 metres (4 ft 11 in) tall.
The leaves, which fall in the dry season, form a rosette on the top of branches.
The fruits are 6 to 20 inches long and contain elongated seeds with a length of 6 mm.
The succulent caudex and the underground tuberous enable the plant to tolerate long periods of drought.
