Description

Baptisia lecontei is a bushy perennial herb with knotty roots that grows from a solid, smooth, solitary, erect, woody stem up to 1 m tall. The petiolate compound leaves are smooth, alternately arranged, and palmately trifoliate with entire margins and green triangulate/lanceolate/folicaceous stipules (small leaf-like growths at the base of the leaf stalks). The bilaterally symmetric flowers form on terminal or axillary racemes and resemble butterflies in shape. They have clawed, orange or yellow petals that are ovoid to obovate in shape with wing and keel petals that are narrow and ear-shaped with obtuse or rounded tips. There are 9 - 10 separate stamens with smooth filaments and a circular style that is persistent in the unilocular legume fruit. The elongated, pubescent legume fruit is oblong or ellipsodial in shape and will persist on the stems after they split or burst open to release the seeds. Those seeds are smooth surfaced with resinous dots and are olive, brown, or black in color.[3][4]

Distribution

B. lecontei occurs throughout the northern two-thirds of Florida and in some counties in Georgia.[5]

Ecology

Habitat

B. lecontei requires open areas and strong, consistent winds for seed dispersal,[6] and prefers higher light levels with 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.[4]

Associated species include Pinus palutris, Cuthbertia rosea, Quercus laevis, Quercus marilandica, Quercus geminata, Quercus falcata, Quercus incana, Prunus serotina, Prunus umbellata, Disopyros virginiana, Rhus copallina, Vaccinium arboreum, Vaccinium stamineum, Rubus cunefolius, and others.[4]

Phenology

The fruit of B. lecontei is a membranous to ligneous legume.[7] This species has been observed flowering from April through July, with peak inflorescence in May and June, and fruiting from June through August.[4][8]

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.[9] Mehlman observe that B. lecontei could be found over 50 meters away from where it originated, evidently by wind dispersal.[6] 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.

Conservation, cultivation, and restoration

Cultural use

A closely related species, B. tinctoria has been historically used to treat scarlet fever, typhus, sore throat, ulcers, and open wounds.[10] It is unknown if all species of Baptisia can be used in these ways.
