Saurauia sparsiflora is a species of flowering plant in the family Actinidiaceae. It is endemic to the Philippines.[2] It was discovered on Mount Santo Tomas by Adolph Daniel Edward Elmer, the American botanist who first formally described the species, and named it after the small number, or sparse (sparsus in Latin),[3] flowers in its inflorescences.
