Family: Loganiaceae R. Br. Ex Mart.
Genus: Geniostoma J.R. Forst. & G. Forst.

Geniostoma is a genus of around 25 species of flowering plants in the family Loganiaceae. They are shrubs or small trees, with inflorescences borne in the axils of the simple, petiolate, oppositely-arranged leaves.[1] The flowers are arranged in cymes, and each is pentamerous.[1] The name Geniostoma derives from the Greek roots Template:lang ("beard") and ; "mouth"), referring to the hairs in the corolla tube of some species.[2] The genus is widely distributed across the Pacific Ocean from Japan, Malesia to Australia in the west, and east to the Tuamotu Archipelago; one species is also found on the Mascarene Islands.[2]

The Hawaiian endemic genus Labordia has been included in Geniostoma by some authors.[2][3] These two genera have been grouped together in the family "Geniostomaceae",[4] but are considered by the Angiosperm Phylogeny Group to be part of a wider Loganiaceae.[5]
