From Wikipedia, the free encyclopedia
This ground-rooting orchid is a common roadside weed at middle elevations in Central America. It is part of a complex of several orange-flowered, weedy species (including Asclepias spp.) that are unrelated but ecologically similar. Species within this group share pollinators as well as habitat, and are believed to exhibit what is known as convergent evolution, where unrelated species "converge" upon similar physical characteristics as a result of similar evolutionary pressures.
