About Macranthera flammea (W.Bartram) Pennell
Macranthera is a monotypic plant genus in the family Orobanchaceae, holding only one species: Macranthera flammea. This species is commonly known by the common names flameflower or hummingbird-flower. It is endemic to the Coastal Plain of the southeastern United States. Macranthera flammea is largely restricted to the Gulf Coastal Plain of the southeastern United States, and is native to the U.S. states of Alabama, Florida, Georgia, Louisiana, and Mississippi. Its range extends as far east as Bulloch County in eastern Georgia. This species grows in and around bogs, bayheads, creeks, ecotones, and seepage slopes, at elevations ranging from sea level up to 100 m (330 ft) above sea level. Macranthera flammea flowers from July to October, and has adapted to produce abundant flowers after fires. Its flowering period overlaps with the arrival of ruby-throated hummingbirds (Archilochus colubris) in its range, when these birds migrate across the Gulf of Mexico.
