Description
"Herbs, whorled or alternate rarely opposite, entire leaves. Flowers lavender, pink, white or yellow, in racemes or spikes, terminating the branches or in terminal corymbs. Flowers perfect, zygomorphic, with 3 small sepals, frequently one of these slightly larger than the others, and 2 larger petaloid sepals (wigs). The 3 petals are united into a tube, 3-lobed at apex, the 2 lateral lobes usually the longer, the center lobe usually lacerate, often thicker in texture; stamens 6-8, united to the corolla tube in 2 rows. Capsule 2 –locular, with one seed in each locule. Seeds dark brown or black, ellipsoid or ovoid, rarely globose, 0.5-3 mm long, usually densely pubescent. The genus has been divided into several genera none of which have distinct characteristics. Orange flowers turn pale yellow on drying, yellow ones bluish green; the pink or lavender ones remain the same color or fade slightly."[1]
"Similar to P. ramose. Stems usually solitary from a rosette, 4-12 dm tall. Basal leaves lanceolate to linear, 4-7 cm long, 3-7 mm wide, rapidly reduced upward. Sepals rounded to an abrupt acute apex, wings oblanceolate to nearly spatulate, 3-3.5 mm long; corolla with 2 clavate lobes at the apex equaling the wings. Seeds purplish black to grayish brown, glabrous and finely reticulate, ovoid, 0.6-0.8 mm long; aril obsolete."[1]
Distribution
P. cymosa is found throughout the southeast coastal plain from North Carolina to Louisiana.[2]
Polygala cymosa is endemic to an area from southeastern New Jersey and Delaware to eastern North and South Carolina, but there is a disjunction between the Carolinas and New Jersey-Delaware.[3]
Ecology
Habitat
P. cymosa is an obligate wetland plant and occurs in habitats such as cypress depressions, pine flatwoods, and depressional wetlands.[4] Associated taxa include Aristida, Hypericum, Dichromena, Sarracenia, Drosera, Eriocaulon, and Pinguicula.[5]
Phenology
P. cymosa has been observed flowering April through July and in September with peak inflorescence in April.[5][6]
Seed dispersal
Seeds have an elaiosome, therefore the seeds are dispersed by ants.[7]
Pollination
Polygala cymosa was observed at the Archbold Biological Station to host leafcutting bees from the Megachilidae family such as Megachile brevis pseudobrevis.[8]
