Orchidantha remains a poorly known genus, found from southern China to Borneo.[4][6] Orchidantha means "orchid-flower", as one of the petals on the flowers is modified into a labellum, like the flowers of orchids.[7] One species, Orchidantha inouei of Borneo, imitates the smell of dung in order to attract small Onthophagus dung beetles as pollinators.[8]
