Crinum oliganthum

Unknown

Overview

A detailed profile for this species is sourced from the IUCN Red List of Threatened Species as assessments become available.

Crinum oliganthum faces severe pressure from agricultural expansion and urban development across its limited range in South Africa's coastal regions. The species' bulbs are heavily harvested for traditional medicine, with commercial collection significantly reducing wild populations. Habitat fragmentation from infrastructure development has isolated remaining populations, limiting genetic exchange and natural regeneration.

Threat summary

Habitat

This bulbous plant occurs in coastal grasslands and rocky outcrops along South Africa's eastern seaboard, typically in well-drained soils with seasonal moisture. It favors open areas with partial shade from scattered shrubs and trees in the coastal belt ecosystem.
