Pachypodium lamerii
This species occurs in Southern Madagascar.
The deciduos leaves are long, not as narrow a geayi and darker green with a bit more of glossy look to them. The leaves have a lighter middle vein that has less of a downward curvature in the length than geayi. The trunk is a smooth greyish silver. Spines are in clusters of three and are sharp and strong. The flowers are white with yellow in the center. Flowers will set in about ten years in good conditions if your lucky. Lamerii should be given full light and plenty of water during the warmer months and considerably less water in the cool months. These are one of the most widely cultivated of the species. Also known as Madagascar Palms. Seedlings grow fairly quickly compared to other Pachypodium species. Lamerii may grow up to 12" annually.
