Description

Jatropha rivae diagram

Jatropha rivae, recognized as an infraspecific taxon within the taxonomic genus Jatropha and situated in the botanical family Euphorbiaceae, boasts a natural range extending from Ethiopia to Tanzania, where it predominantly inhabits arid desert landscapes and dry shrubland biomes.Documented occurrences of this species notably include locales such as Sidamo and Dolo in Ethiopia.

It demonstrates ecological adaptability across a spectrum of habitats, thriving in Acacia-Commiphora bushlands characterized by alluvial soils, deep sands, and stony outcrops on limestone substrates, thriving at elevations spanning from sea level to approximately 1,150 meters. Attaining stature heights of around 1.50 meters, it persists in a state of wild propagation, albeit with cultivation methodologies yet to be comprehensively elucidated.

In addition to its ecological significance, Jatropha rivae holds notable cultural and medicinal prominence within indigenous communities. Traditional practices involve the ingestion of root segments for their potent purgative properties and the preparation of root infusions utilized as emetics and fever remedies.

This botanical resource serves practical ends, as its combustion within domestic settings serves as a deterrent against airborne pests such as flies and mosquitoes, owing to its distinctive olfactory properties. Twigs derived from the shrub are also strategically employed as bedding materials, augmenting the repellant effects beneath sleeping arrangements. The multifaceted utilization of Jatropha rivae underscores its integral role within local ecosystems and cultural practices, manifesting its broader ecological and socio-economic significance.
