Saintpaulia ulugurensis

Stable

Overview

Streptocarpus ulugurensis is a species of flowering plant in the family Gesneriaceae. It is an herbaceous perennial endemic to the Uluguru Mountains of Morogoro Region of Tanzania.

Saintpaulia ulugurensis faces severe threats from habitat destruction due to agricultural expansion and human settlement in the Uluguru Mountains. The species' extremely restricted range makes it particularly vulnerable to localized disturbances, while collection for the horticultural trade has further reduced wild populations. Climate change poses an additional threat by altering the specific microclimatic conditions this endemic violet requires.

Threat summary

This endemic African violet inhabits moist, shaded rock crevices and cliff faces in the montane forests of the Uluguru Mountains in Tanzania. It requires specific microclimatic conditions with high humidity and filtered light, typically growing at elevations between 1,200-2,000 meters.

Frequently asked questions

Why is Saintpaulia ulugurensis classified as Critically Endangered?
Saintpaulia ulugurensis is classified as Critically Endangered — facing an extremely high risk of extinction in the wild — because population sizes are very small, declining sharply, or restricted to a tiny range. Saintpaulia ulugurensis faces severe threats from habitat destruction due to agricultural expansion and human settlement in the Uluguru Mountains. The species' extremely restricted range makes it particularly vulnerable to localized disturbances, while collection for the horticultural trade has further reduced wild populations. Climate change poses an additional threat by altering the specific microclimatic conditions this endemic violet requires.
Where does Saintpaulia ulugurensis live?
Saintpaulia ulugurensis occurs in Tanzania. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
