Description
This plant is erect[1].
Generally, the genus Galactia are "trailing or twining, climbing, perennial, herbaceous or woody vines or erect, perennial herbs or rarely shrubs. Leaves 1-pinnate, usually 3-foliolate (or rarely 1-,5-7-,9-folilolate); leaflets entire, petiolulate, stipellate. Racemes axillary, pedunculate with few to numerous, papilionaceous flowers borne solitary or 2-several at a node, ech subtended by a bract and fusion of the 2 uppermost, with the laterals usually shorter than the uppermost and lowermost; petals usually red, purple, pink or white; stamens diadelphous or elsewhere occasionally monadelphous; ovary sessile or shortly stipitate. Legume oblong-linear to linear, few-many seeded, compressed, straight or slightly curbed, dehiscent with often laterally twisting valves."[2]
Specifically, for G. erecta species they are "erect perennial with glabrous or sparsely pubescent stems, mostly 2-4 dm tall. Leaves 3-foliolate with rachis 1-2 mm long; leaflets linear-oblong to oblong or elliptic, mostly 1.5-4 cm long, glabrous. Racemes 1-2 cm long, subsessile; flowers 1-6, on short-pubescent pedicels 1-3 mm long subtended by triangular-subulate bracts 1-1.5 mm long; bractlets triangular-to linear-subulate, 1-2 mm long. Calyx appressed short-pubescent, tube 2-3 mm long, lobes 2-3 mm long; petals pale purple to white, the standard 7-8 mm long. Legume 2-4 cm long, 5-8 mm broad, 6-10 seeded, with short-pubescent valves and sutures." [2]
Distribution
Ecology
Habitat
This species has been found in open longleaf pine-wiregrass flatwoods along gum swamps, wiregrass savannas, pine-oak upland forests, and clearings within pine flatwoods. This species does well in open light environments in dry loamy sands, drying sand, and sandy-peaty wet soils.[1]
Associated species seen growing with Galactia erecta include Pinus palustris, Pinus elliotii, Aristida stricta, Quercus species, Tephrosia florida, Aristida, Croton, Berlandiera, Asclepias, Tetragonotheca, Galactia mollis. [1]
Phenology
It has been observed to have corolla white or light yellowish flowers.[1] “A purple flowered perennial herb about 1 foot high, occurring in dry pine lands of the Coastal Plain from north Carolina to Louisana. Seeds have been recorded from stomach of a single bobwhite.”[3] It has been seen flowering from April to August with peak inflorescence in May and June.[1][4] It has been observed fruiting from June to July and in September.[1]
Seed dispersal
This species disperses by gravity. [5]
Fire ecology
It has been found in recently burned open scrub.[1]
