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 (FSU Herbarium). This species does well in open light environments in dry loamy sands, drying sand, and sandy-peaty wet soils (FSU Herbarium).
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 (FSU Herbarium).
Phenology
It has been observed to have corolla white or light yellowish flowers (FSU Herbarium). “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 June and fruiting from June to July and in September (FSU Herbarium).
Seed dispersal
According to Kay Kirkman, a plant ecologist, this species disperses by gravity. [4]
Fire ecology
It has been found in recently burned open scrub (FSU Herbarium).
