Geniostoma rupestre is a species of flowering plant in the family Loganaceae. It is a shrub or tree which ranges from Taiwan and Malesia to Papuasia, Queensland, New Zealand, and the western and central Pacific islands.[1][2]

Geniostoma rupestre is a shrub or small tree from 2 to 5 meters tall, and occasionally up to 12 meters tall. It grows in both primary and secondary tropical moist forests, often in open areas in secondary forests, from sea level to 2,800 meters elevation. Plants often have a straggling form in the forest shade, with more dense and compact growth in open sunny areas.[2]
