Origin and Habitat: Sterculia africanaSN|33502]]SN|33502]] ssp. socotrana is one of the more characteristic species of the coastal plains and low inland hills of Socotra. The vegetation consist of open deciduous shrubland dominated by the endemic Croton socotranus and scattered trees of Euphorbia arbusculaSN|33364]]SN|33364]], Dendrosicyos socotranus, and Ziziphus spina-christi. Grasses and herbs develop after sufficient rainfall. The most widespread vegetation type is a distinctive species-rich open shrubland found on the coastal foothills and the limestone escarpments. Two endemics, Croton socotranus and Jatropha unicostataSN|22492]]SN|22492]], are the main shrubs present and are the most abundant plants on Socotra. Succulent trees, such as Euphorbia arbusculaSN|33364]]SN|33364]], Dracaena cinnabariSN|32990]]SN|32990]], and Adenium obesumSN|116]]SN|116]] spp. socotranum and emergent trees, such as Boswellia spp., Sterculia africanaSN|33502]]SN|33502]] ssp. socotrana, and Commiphora spp. are also present (Davis et al. 1994). The largest of the trees of the region is Sterculia africanaSN|33502]]SN|33502]] ssp. Socotrana.

Description: Sterculia africanaSN|33502]]SN|33502]] ssp. socotrana is a morphological form endemic to Socotra island not easily distinguishable from Sterculia africanaSN|33502]]SN|33502]] (ssp. africana) if not for the geographical provenance. The leaves are glabrous, lobate far apart from each other. Typical of this pachycaul tree is the plate-shaped peeling bark of the barrel-shaped trunk and main branches.
