Macranthera is a monotypic plant genus in the family Orobanchaceae containing only the species Macranthera flammea, commonly known as the flameflower or hummingbird-flower.[1][3] It is endemic to the Coastal Plain of the south-eastern United States.

Distribution and habitat

Largely restricted to the Gulf Coastal Plain of the south-eastern United States, Macranthera flammea is native to the states of Alabama, Florida, Georgia, Louisiana, and Mississippi, ranging as far east as Bulloch County in eastern Georgia.[1][3][4] It occurs in and around bogs, bayheads, creeks, ecotones, and seepage slopes from sea level up to 100 m (330 ft) above sea level.[3][4]

Ecology

Macranthera flammea flowers from July to October,[3] and has adapted to flower prolifically following fires. The flowering period coincides with the arrival of ruby-throated hummingbirds (Archilochus colubris) in its range as part of their migration across the Gulf of Mexico.[4]
