Prismatomeris andamanica

Unknown

Overview

Prismatomeris fragrans is a species of tree in the Rubiaceae family. It is found in Southeast Asia. The subspecies Prismatomeris fragrans subsp. andamanica is found only on the Andaman Islands.

Prismatomeris andamanica faces severe threats from deforestation and habitat conversion across the Andaman Islands, where its extremely limited range makes it vulnerable to any disturbance. Coastal development and infrastructure expansion have fragmented the remaining forest patches where this endemic shrub occurs. The species' restricted distribution to specific soil types and microclimatic conditions means that even small-scale habitat alterations can have disproportionate impacts on population viability.

Threat summary

Habitat

This endemic shrub inhabits tropical evergreen forests and forest edges in the Andaman Islands, typically growing in well-drained soils at low to moderate elevations. It occurs in both primary forest understory and secondary growth areas, showing preference for partially shaded environments with consistent moisture levels.
