Macbridea alba is a rare species of flowering plant in the mint family known by the common name white birds-in-a-nest.

[1] The open flowers and rounded buds sitting on the cluster of green bracts resemble white birds and eggs in a nest, giving the plant its common name.

[2] This mint grows in pine flatwoods, seeps, wet savannas, and the ecotones next to swamps and sandhills.

Urban development threatens the local habitat as residential areas are constructed and associated utilities such as roads are built and maintained; many occurrences of the plant are on roadsides and are vulnerable during this process.

Fire prevents the ecological succession of the flatwoods, keeping large woody vegetation from building up and shading out the herb layer of the understory.
