Portulaca philippii: Characteristics and Natural Habitat
Thriving in some of the most extreme environments on Earth, Portulaca philippii has adapted perfectly to its severe natural habitat. Ivan Murray Johnston was the first botanist to formally describe this species, which flourishes across high-altitude and arid zones in South America. The plant is particularly notable for its presence in the extremely dry conditions of the Atacama Desert.
