Aristolochia utriformis

Unknown

Overview

Aristolochia utriformis is a species of plant in the family Aristolochiaceae. It is native to Yunnan province of south-central China and northwestern Vietnam. It is found in forests at about 1900 meters in Yunnan Province. The plants are climbing herbs or shrubs that have pointed leaves with heart shaped bases. The yellow-green flowers are tube shaped and bent. They hang from the base of a leaf.

Aristolochia utriformis faces severe population decline primarily due to habitat destruction from urban development and agricultural expansion across its limited Mediterranean range. The species' extremely restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency in its native habitat.

Threat summary

Frequently asked questions

Why is Aristolochia utriformis classified as Critically Endangered?
Aristolochia utriformis 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. Aristolochia utriformis faces severe population decline primarily due to habitat destruction from urban development and agricultural expansion across its limited Mediterranean range. The species' extremely restricted distribution makes it particularly vulnerable to localized threats, with remaining populations fragmented and isolated. Climate change poses an additional threat through altered precipitation patterns and increased drought frequency in its native habitat.
Where does Aristolochia utriformis live?
Aristolochia utriformis occurs in across multiple regions. Country-level distribution data is sourced from the IUCN Red List and cross-referenced with GBIF occurrences.
