About Antidesma excavatum

Antidesma excavatum (Antidesma excavatum var. excavatum) is a post-contact introduced tree documented on Kauaʻi through cultivation records. In its native range the variety spans coastal, riverine, swamp-edge, lowland and montane forest settings and persists in both primary and secondary vegetation. Its small fleshy fruits are eaten by people, and the monograph reports cultivation as a minor fruit tree in eastern Malesia with some human-mediated dispersal likely there. Those relationships describe the native and cultivated range; the available Kauaʻi evidence supports only maintained living plants and does not show establishment beyond cultivation.

Record type: Species

Kauaʻi occurrence and status

Kauaʻi occurrence: Recorded on Kauaʻi
Origin: Introduced
Conservation status: Not yet assessed
Evidence date: 2026-10-06
Evidence limits: Current extent is unassessed; public locality is island level only.

Habitat and ecology

Habitats: Not yet assessed
Food and resource needs: Not yet assessed
Reproduction: The species is dioecious, so male and female flowers occur on separate trees and both sexes are required for sexual fruit and seed production. Tiny apetalous flowers are borne in axillary branched inflorescences; female flowers develop into one-seeded fleshy drupes on branched infructescences, and propagation is by seed. No flowering, fruiting, dispersal or seedling recruitment has been documented for the Kauaʻi collection.
Shelter: Not yet assessed
Growth form: Evergreen wet-tropical tree, rarely a shrub

Threats and conservation

Monitoring: Not yet assessed
Data gaps: Current population extent and trajectory · Additional species-specific ecological and conservation sources
