Pachypodium Habitats - Substrate


Pachypodium grows in various types of substrates. In some cases, some species inhabit only one substrate. Pachypodium ambongense, P. decaryi, and P. windsorii grow exclusive on calcareous rocks. P. brevicaule and P eburneum are contained to quartzite. Other cases demonstrate that species can grow in multiple substrates. P. cactipes, P. densiflorum, and P. horombense dwell mainly on gneiss and granite. P. rutenbergianum grows in various substrates, but particularly on sand and laterite. Sand provides a substrate for P. geayi and P. rosulatum. In African, P. namaquanum can grow on three substrates: granite, quartzite, and sand. The other species likewise can be found on myriad, various substrates: limestone, granite, gneiss, sandstone, quartzite, sand, schist, tert calcareous, sandy soils, basalt, and sandy loam in Madagascar. In Africa, the substrate ranges from: quartzite, sandstone, clay, gravel, sandy soil, dolomite, granite, schist, basalt, limestone, rhylite, and dolerite. The more adaptable the taxon is to substrate seems to be indication of how specialized the species is within its habitat in the landscape and climate.
