Mutisia acuminata
Native to the Andes of Peru and Bolivia, this woody shrub has a scrambling habit and leaves divided into elliptical leaflets. In Peru, it grows in mountain scrub at about 9,800 to 12,500 feet. Its large orange flower heads have elongated overlapping bracts, broad outer ray florets and narrower central florets. Black metaltail hummingbirds visit the flowers for nectar, sometimes taking it through openings at the flower base rather than through the normal entrance. Photographed in Peru.
