Notes

In 1965 the species was only seen from Malaya and Sumatra; it has now also been collected in the Gunung Mulu National Park, Sarawak. A dubious specimen comes from Mt Kinabalu, Sabah.
The species differs from the rather similar Prunus grisea var. tomentosa in the stiff and hard (not papyraceous) leaves.
The epithets brevifolia and scortechinii were used previously in Prunus.
