A new species of Leguminosae (Caesalpinioideae), Browneopsis sanintiae Silverst., is described from the northern end of the Cauca Valley in the department of Risaralda, in western Colombia. It resembles the Amazonian species B. ucayalina Huber, but differs in having one vestigial petal or lacking petals (vs. three to four vestigial petals in B. ucalayina), fewer stamens, and pollen usually monoporate (vs. tetraporate in B. ucayalina). This is the first report of the genus Browneopsis Huber from the Cauca Valley.
