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]

Contents

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]
