Taxonomic notes
The genus name comes from the Greek word "bapto" meaning to dye, the specific epithet means white.[1]
Synonyms: B. lactea (Rafinesque) Thieret var. obovata (Larisey) Isely; B. lactea var. pendula (Larisey) B.L. Turner; B. pendula Larisey[2]
Varieties: B. pendula var. obovata Larisey[2]
Description
For the Baptisia genus, the group are rhizomatous perennial herbs which blacken when dried. The leaves are 3-foliolate or rarely simple. The flowers are papilionaceous (butterfly shaped), either solitary or in axillary or in terminal racemes. The bell-shaped, 4 - 5 lobed calyx is persistent, and the orbicular to reniform petals can be white, cream, yellow or blue in color, and they are usually reflexed and shorter than the wing and keel petals. There are 10 stamens, the filaments are distinct, the ovary is stalk-like in shape, and the legume has a papery to almost woody texture, is inflated, stalked, globose to cylindric in shape, and contains many small seeds.[3]
Specifically, for Baptisia alba, the plants are glaucous and smooth (or close to it) and grow between 0.5 - 1.2 m tall. The leaves contain 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 15 - 50 cm long. The 2 pedicels grow up to 4 - 12 mm long subtended by temporary bracts that grow up to 5 - 7 mm long. The calyx is smooth (glabrous) except for the short-ciliate margin, and when dried changes to a greenish yellow to straw color. The flower is white in color, and the keel and wing petals grow up to 1.2 - 1.8 cm long. The legume is usually erect, light brown in color, cylindric in shape, and grows up to 2 - 3.5 cm long and up to 5 - 10 mm in diameter.[3]
Distribution
Native to the southeastern United States from Virginia to central Florida.[4]
Ecology
Habitat
Baptisia alba is found dry habitats such as 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. It can also be found in some disturbed habitats, namely on moist roadsides and along hiking trails and railways. 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.[5] B. alba has shown resistance to regrowth in reestablished longleaf pine woodlands that were disturbed by agricultural practices in South Carolina, making it an indicator species for remnant woodlands.[6] Additionally, B. alba has been found to be a decreaser in its long-term response following cessation of repeated soil disturbance.[7]
Phenology
B. alba grows from a rhizomatous root sytem with a taproot sending up one to several stems.[8] It exhibits asynchronous flowering.[9] Blooms April through July.[4] The fruit is a membranous to ligneous legume.[10] It has been observed to flower in north Florida from March to May and also in December, with peak inflorescence in March and April.[11]
Seed dispersal
The legume pod dehisces vertically releasing seeds.[10]
Seed bank and germination
If propagating from seed, they can be soaked in hot water for 1-2 days, and they will germinate within 20 days. Otherwise, they can be scarified (nicking the seed coat with a knife or file before planting) or the root can be divided for a new transplant.[4]
Fire ecology
It inhabits annually burned pinelands, which implies fire tolerance.[5] A deep taproot allows for resprouting after fires.[4] There is a greater reproductive productivity in burned areas.[9]
Pollination
The bee Bombus sp. is the major pollinators of Baptisia alba[9]; Bombus bimaculatus has been observed pollinating the plant.[12]
Herbivory and toxicology
It is known to be fatal for cows to ingest B. alba, and irritating to humans if ingested. However, it is of special value to native bees since it attracts large numbers.[13]
Conservation, cultivation, and restoration
This species takes several years to establish, however, once established it is extremely long lived[4].
Cultural use
A closely related species, B. tinctoria has been historically used to treat scarlet fever, typhus, sore throat, ulcers, and open wounds.[14] It is unknown if all species of Baptisia can be used in these ways.
