Geniostoma is a genus of around 49 species of flowering plants in the family Loganiaceae.^[1] They are shrubs or small trees, with inflorescences borne in the axils of the simple, petiolate, oppositely-arranged leaves.^[2] The flowers are arranged in cymes, and each is pentamerous.^[2]

The name Geniostoma derives from the Greek words γένειον (geneion; "beard") and στόμα (stoma; "mouth"), referring to the hairs in the corolla tube of some species.^[3] 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.^[3]

The Hawaiian endemic genus Labordia is included in Geniostoma by Plants of the World Online and other authors.^[3]^[4]^[1] The Hawaiian species are commonly known as labordias or as Kamakahala in Hawaiian.^[5] These two genera have been grouped together in the family "Geniostomaceae",^[6] but are considered by the Angiosperm Phylogeny Group to be part of a wider Loganiaceae.^[7]
