Pachypodium (Lindl. 1830)

They are undoubtedly distinguished by their thickened base of the stem, a characteristic that gives the genus its name, sometimes forming truly thick trunks in proportion to the plant. These stems serve as their main water reserve. Highly adapted to arid climates, they take the form of shrubs or small trees, many with spines on the branches and deciduous leaves. They exhibit showy flowering, usually white or yellow and large in size. They are common in gardening, although they require care to prevent stem rot.
Etymology: From the Greek pachy- ("thick") and -podium ("foot"), in reference to the characteristic thickening of its stems.
Place of Origin: Madagascar and southern Africa.
