The enigmatic Galipea ossana, described in 1822 and known from the type specimen said to originate from Cuba and only one other collections made before 1841 in a locality called San Diego, is reconsidered. Light microscopic and scanning electron microscopic examination of flower structure, fruits and pollen grains of the scarce material available show that the species actually is the only representative of the genus Angostura on the Antilles and a W Cuban endemic, closely related to A. trifoliata from Venezuela. The combination A. ossana is validated and the diagnostic features of this species and of A. trifoliata are illustrated.
