Are Beaucarnea and Streptosolen both a genus of flowering plants?
Streptosolen Streptosolen is a genus of flowering plants with a single species, Streptosolen jamesonii, the marmalade bush. It is an evergreen shrub of the Solanaceae family that produces loose clusters of flowers gradually changing from yellow to red as they develop, resulting in an overall appearance resembling orange marmalade (thus the name), found in open woodlands of Colombia, Ecuador, and Peru.
Grevillea Grevillea is a diverse genus of about 360 species of evergreen flowering plants in the family Proteaceae, native to rainforest and more open habitats in Australia, New Guinea, New Caledonia, Sulawesi and other Indonesian islands east of the Wallace Line.
