Apocynaceae Family of plants

Apocynaceae is a family of flowering plants that includes trees, shrubs, herbs, stem succulents, and vines, commonly known as the dogbane family, because some taxa were used as dog poison. Members of the family are native to the European, Asian, African, Australian, and American tropics or subtropics, with some temperate members. The former family Asclepiadaceae is considered a subfamily of Apocynaceae and contains 348 genera. A list of Apocynaceae genera may be found here.

Pachypodium is a genus of succulent spine-bearing trees and shrubs, native to Madagascar and Africa. It belongs to the family Apocynaceae.

<i>Pachypodium lealii</i> species of plant

Pachypodium lealii, the bottle tree, is a species of plant included in the genusPachypodium. The scientific name derives from the 19th century Portuguese geologist Fernando da Costa Leal, who described the bottle tree during an exploration in southern Angola.

<i>Pachypodium lamerei</i> species of plant

Pachypodium lamerei is a species of flowering plant in the family Apocynaceae. It is a stem succulent, photosynthesizing mainly through its trunk, and comes from the island of Madagascar, off the east coast of Africa. It has large thorns and leaves mostly just at the top of the plant, and large, fragrant flowers. The species has become one of the best known pachypodiums in cultivation, being relatively easy to propagate and grow. In cultivation it is often marketed as the Madagascar palm, despite its not being a palm at all. A variety called "Ramosum" has been described. It is distinguished mostly by a dwarf growth habit.

The history of the genus Pachypodium as a scientific classification began in 1830, when the genus was first used in a taxonomical system by John D. Lindley, who placed a single species, P. tuberosum, in it. Lindley believed that this species was identical with one identified in 1781 as Echites succulenta, which would make "Pachypodium" a taxonomical synonym of "Echites".

Plants belonging to the genus Pachypodium vary widely from each other in some aspects, but also share a number of basic common traits. Each species is adapted to the specific environment which it inhabits, but all species of the genus share certain anatomical and metabolic traits, reflecting their common evolutionary ancestry.

The taxonomy of the Pachypodium genus is the study of the species and subspecies in the genus Pachypodium. There are currently 25 recognized species in the genus, of which 17 are shrubs and eight are trees.

Pachypodium bicolor is a species of plant in the family Apocynaceae.

Pachypodium habitats consist of isolated, specialized, micro–environmental niches, generally xeric, rocky, frost-free areas within parts of western Madagascar and southern Africa. Pachypodium species are often indifferent to the regional ecological, biotic zone of vegetation, a fact which explains some of Pachypodium morphology and architecture. The large scale vegetation zones are in some cases irrelevant to the micro-environments of Pachypodium, in the sense that the xeric niches may be embedded in larger mesic biomes.
