Varieties: none.[3]
Description
Balduina uniflora is a dioecious perennial that grows as a forb/herb,[2] possessses fleshy roots[4] that have a mean depth of 15.75 cm and porosity of 0.0%,[5] and reproduces vegetatively from root stocks. This species can reach heights of 0.7 - 1.0 m. When in bloom there are 1 - 3 heads, each with 8 - 22 yellow ray flowers that are 5.5 - 8.2 mm long and 1 - 2 mm wide.[4]
Distribution
Balduina uniflora is endemic to the longleaf pine range[6] found from eastern Louisiana, eastward throughout the panhandle of Florida and southeastern Georgia, and northward to southeastern North Carolina.[2]
Ecology
Habitat
This species is found in wet pine savannas, pine flatwoods,[1] and the margins of pitcher-plant bogs.[4] It has also been observed in moist sand roadsides, wet peaty soil in pocosin, swamps, and mesic disturbed sites.[7] B. uniflora does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[8]
Balduina uniflora is an indicator species for the Panhandle Seepage Savannas community type as described in Carr et al. (2010).[9]
Associated species: Liatris sp., Sporobolus sp., Andropogon sp., Schizachyrium sp., Eupatorium sp., Pinus palustris, Habenaria ciliaris, Lilium catesbaei, Eragrostis elliottii, Eriocaulon decangulare, Rhynchospora sp., Bigelowia sp., Hypericum sp., Serenoa repens, Xyris flexuosa, Sabatia brevifolia, Kalmia hirsute, Polygala lutea, Sorghastrum secundum, Quercus pumila, Seymeria cassioides, Helianthus heterophyllus, Juncus sp., Ilex glabra, Rhexia sp., Marshallia graminifolia, Pityopsis sp., and Carex sp.[7]
Phenology
In the southeastern and mid-Atlantic United States, flowering occurs from late July through September.[1] Another, study reports flowering starting in June.[4] It has been observed to flower from November to Janurary, March and April, and July through September, with peak inflorescence in September.[10]
Seed dispersal
This species is thought to be dispersed by wind. [11]
Fire ecology
In Mississippi pine barrens, flowering increased significantly from one year after a burn into the second year following a burn.[12]
Pollination
It attracts bumblebees and butterflies which pollinates it.[13] Pollen grains are 40-45 µm in diameter.[4]
Use by animals
Henslow's sparrows were observed to eat B. uniflora as a part of their diet.[14]
