Osa pulchra
Osa pulchra is a species of rare flowering plant in the monotypic genus Osa, in the family Rubiaceae. There are only two known populations in Costa Rica, with less than a total of thirty individual plants and a small population in Panama. The name of the plant's genus is derived from the Osa Peninsula, which is located in southwestern Costa Rica. The flower has been cultivated in several botanical gardens, including the New York Botanical Garden and the Huntington Botanical Garden. 

"Osa pulchra" has large white, trumpet-shaped, pendulous flowers similar to many plants in the family, Solanaceae, such as "Brugmansia" and "Solandra". The flowers are pendent, borne on long pedicels, fused-petals and an elongated corolla. The blooms are highly fragrant at night and are most likely pollinated by bats (chiropterophily).
