Senna viarum

A tree native to Colombia and Ecuador, it has compound leaves with paired, elongated leaflets. Clusters of bright yellow flowers appear at the branch tips, with broad petals surrounding curved, dark brown anthers. The crown can become densely covered in blooms. In Colombia, it occurs in the Andes at elevations of about 6,600 to 8,900 feet. Photographed in the eastern Andes mountain range of Colombia.
