Taxonomic Notes

Synonym: Endorima uniflora (Nuttall) Rafinesque [1]


Balduina uniflora is a dioecious perennial that grows as a forb/herb.[2] Its roots are fleshy[3] and have a mean depth of 15.75 cm and porosity of 0.0%.[4] It reproduces vegetatively from root stocks and can reach heights of 0.7-1.0 m. Inflorescence contain 1-3 heads, each with ray flowers 8-22, 5.5-8.2 mm long and 1-2 mm wide. Flowers are yellow.[3]


It is found from eastern Louisiana, eastward throughout the panhandle of Florida and southeastern Georgia, and northward to southeastern North Carolina.[2]



This species is found in wet pine savannas, pine flatwoods,[1] and the margins of pitcher-plant bogs.[3]


In the southeastern and mid-Atlantic United States, flowering occurs from late July through September.[1] Another, study reports flowering starting in June.[3]

Seed dispersal

This species is thought to be dispersed by wind. [5]

Fire ecology

In Mississippi pine barrens, flowering increased significantly from one year after a burn into the second year following a burn.[6]


It attracts bumblebees and butterflies which pollinates it.[7] Pollen grains are 40-45 µm in diameter.[3]
