Euphorbia quadrilatera
Overview
A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.
Euphorbia quadrilatera faces severe pressure from agricultural expansion and urban development across its limited range in South Africa's Eastern Cape Province. Overgrazing by livestock has degraded much of its natural thicket habitat, while invasive plant species compete for resources in remaining fragments. The species' slow growth rate and specialized habitat requirements make recovery particularly challenging once populations are disturbed.
Habitat
This succulent shrub is endemic to the Albany Thicket biome of South Africa's Eastern Cape Province, where it grows in dense, spiny vegetation on rocky slopes and well-drained soils. It typically occurs in areas with winter rainfall patterns and is adapted to the region's semi-arid conditions.
