Diplodiscus hookerianus

Unknown

Overview

Diplodiscus hookerianus is a species of flowering plant in the family Malvaceae sensu lato. It is a tree endemic to Peninsular Malaysia.

Diplodiscus hookerianus faces severe pressure from deforestation and habitat fragmentation across its limited range in the Western Ghats of India. The species is particularly vulnerable to agricultural expansion and infrastructure development that destroys the moist forest understory where it thrives. Climate change poses an additional threat by altering the humid microclimatic conditions essential for this moisture-dependent species.

Threat summary

Habitat

This species inhabits the moist understory of tropical evergreen forests in the Western Ghats, typically found on decaying logs, leaf litter, and moss-covered surfaces in areas with high humidity. It requires the specific microclimatic conditions of undisturbed forest floors with consistent moisture levels.
