Request ID. Apocynaceae ?: 5 high res. images
Observation: 10/02/23. Riung District, Flores, Indonesia.
Description: It is a small tree that can reach a height of 3m (from my observations). Presence of white latex. Whorled phyllotaxis. Orange berry like fruit. From non-direct information, he would have small white flower.
But in Apocynaceae familly there is no berry like fruit species right ? Except this character, all those informations lead me to an Apocynaceae.
Habitus: Very common in all dry tropical forest with sea influenced climate. Up to an altitude of 400m.
Use: The plant would be used to facilitate the childbirth (and abort)
First ID: Ochrosia sp. ?
