Pachypodium lealii subs. saundersii (best known as Pachypodium saundersii) is a fat pot-bellied stem-succulent. It is one of the commoner Pachypodiums in cultivation. It produces terminal clusters of large white flowers tinged with purple, they are long-tubed and adapted to pollination by moths. The stem is bottle-shaped, often wider than it is tall, growing to 1.5m (5 ft) in diameter. It becomes papery and tears with age. Branches appear above the main stem and are covered with thick spines. Leaves appear all along the branches being light green, smooth, and somewhat shiny with a white midriff.
