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]
