Notes
The two specimens cited with the original description seem to be conspecific with De Wilde & De Wilde-Duyfjes 14087 from Mt Ke-tambe and with the sterile specimen Meijer 6434 from Mt Kerinci, both also from Sumatra but rather wide apart. The species belongs to sect. Mesopygeum and is obviously related to Prunus grisea and P. ceylanica, but the very long racemes and the rather large flowers are differentiating. It is entered here because of the insufficient data on the fruits. The description given rests on the field note of De Wilde c.s. 14087, but on the herbarium specimens only some immature fruits are present and a possibly full-grown one which is subglobular and measures 8 by 7 mm, with some few hairs.
