Taxonomic notes

The genus name comes from the Greek word "bapto" meaning to dye[1].

Distribution

B. lecontei occurs throughout the northern two-thirds of Florida and in some counties in Georgia.[4]

Ecology

Habitat

B. lecontei requires open areas and strong, consistent winds for seed dispersal.[5] It also prefers higher light levels and moist to dry sandy soils like loamy sand and loose sand. It is found in longleaf pine-oak sandhill communities, shrub oak ridges, and pine flatwoods. However, it can also be found in certain disturbed habitats such as power line corridors, roadsides, railways, and cleared areas.[2]

Associated species include Pinus palutris, Cuthbertia rosea, Quercus laevis, Q. marilandica, Q. geminata, Q. falcata, Q. incana, Prunus serotina, P. umbellata, Disopyros virginiana, RHus copallina, Vaccinium arboreum, V. stamineum, Rubus cunefolius, and others.[2]

Phenology

The fruit of B. lecontei is a membranous to ligneous legume.[6] This species has been observed flowering from April through July, with peak inflorescence in May and June, and fruiting from June through August.[2][7]

Seed dispersal

Baptisia lecontei uses tumbleweed dispersal, a type of long-distance dispersal mechanism by which means the whole or a part of the plant serves to disperse seeds by being blown into the wind.[8] Mehlman observe that B. lecontei could be found over 50 meters away from where it originated, evidently by wind dispersal.[5] Other dispersal mechanisms include movement in heavy rainstorms, Florida Harvester Ants, and if rooted, the seeds fall to the ground. Legume pods dehisce vertically to release seeds.
