Pachypodium lamerei is a species of flowering plant in the family Apocynaceae.
Pachypodium lamerei has a tall, silvery-gray trunk covered with sharp 6.25 cm spines. Long, narrow leaves grow only at the top of the trunk, like a palm tree. It rarely branches. Plants grown outdoors will reach up to 6 m (20 ft), but when grown indoors it will slowly reach 1.2–1.8 m (3.9–5.9 ft) tall.
Plants grown outdoors develop large, white, fragrant flowers at the top of the plant. They rarely flower indoors.The stems of Pachypodium lamerei are covered in sharp spines, up to five centimetres long and grouped in threes, which emerge almost at right angles. The spines perform two functions, protecting the plant from grazers and helping with water capture. Pachypodium lamerei grows at elevations up to 1,200 metres, where sea fog from the Indian Ocean condenses on the spines and drips onto the roots at the surface of the soil.
