It is closely related to the genus Browallia, within which it was originally placed. The single species, Streptosolen jamesonii, the marmalade bush or fire bush, is an evergreen shrub bearing loose clusters of flowers which change gradually from yellow to red as they develop, resulting in an overall appearance resembling orange marmalade (whence the name), found in open woodlands in Colombia, Venezuela, Ecuador, and Peru. The plant has become naturalized in certain localities in Hawaii.
The red colouration (at maturity) of the flowers of Streptosolen jamesonii is typical of that of bird-pollinated flowers, as also is their lack of a strong scent and secretion of a great deal of nectar. The iridescent green hummingbird species Chlorostilbon poortmani, the short-tailed emerald, is a frequent visitor to the flowers of Streptosolen jamesonii, pollinating them as it hovers to sip their nectar.
