Description
For the Baptisia genus, the group are rhizomatous perennial herbs which blackening when dried. The leaves are 3-foliolate or rarely simple. The flowers are papilionaceous, either solitary or in axillary or in terminal racemes. The calyx is persistent, is 4-5 toothed (or lobed), is campanulate, the upper lip is entire, the is notched or 2-lobed. The petals can be white, cream, yellow or blue in color. The petals are orbicular to reniform and usually reflexed and are shorter than the wing and keel petals. There are 10 stamens, the filaments are distinct, ovary stipitate in shape. The legume has a papery to almost woody feel in texture, is inflated, stalked, globose to cylindric in shape, and contains many small seeds (Radford 1964).
Specifically, for Baptisia alba, the plants are glaucous, glabrous or close to it. The plants grow up to 0.5-1.2 m tall. The leaves contains the 3-foliolate, the leaflets are elliptic, oblanceolate to obovate in shape, and growing up to 2-4 (6) cm long, and 0.8- 1.5 cm wide. The stipules become deciduous, deltoid to lanceolate, and grow up to 5 mm long. The racemes are long, slender, and terminal, and growing up to 1.5-5 dm long. The (2) pedicels grow up to 4-12 mm long subtended by caducous bracts that grow up to 5-7 mm long. The calyx is glabrous except for the short-ciliate margin. When dried, changes to a greenish yellow to straw color. Of the calyx, the upper lip is entire or slightly emarginated, the corolla is white in color, and the keel and wing petals grow up to 1.2-1.8 cm long. The legume is usually erect, is light brown in color, is cylindric in shape, and grows up to 2-3.5 cm long and up to 5-10 mm in diameter (Radford 1964).
Distribution
Ecology
Habitat
Baptisia alba is found in pine flatwoods, along the edges of mesic thickets and bottomland woodlands, in open upland pine-hardwood sand ridges, well-drained hardwood hammocks, and open upland woods (FSU Herbarium). It can also be found in some disturbed habitat, namely on moist roadsides and along hiking trails and railways (FSU Herbarium). This species appears in a range of light levels, from shady to sunny, and in mostly sandy soil types such as loamy sand and drying sandy loam (FSU Herbarium).
Phenology
This species has been observed flowering from February through July, and fruiting from May through July (FSU Herbarium).
Fire ecology
It inhabits annually burned pinelands, which implies fire tolerance (FSU Herbarium).
