Description
“Repent or erect, usually branched, short-lived perennials, or rarely annual. Floral parts in 4-7’s; hypanthium is not prolonged beyond the ovary. Capsules longitudinally or poricidally multiseriate, rarely uniseriate. Most of the erect species produce basal offshoots, which have ovate to obovate leaves, in the late summer and fall. Bracteoles occur in pairs on the pedicel or stipe or the base of the hypanthium.”[2]
"Stems erect, usually branched, usually glabrous below, to 1 m tall. Leaves alternate, lanceolate, or elliptic, usually glabrous, to 7.5 cm long and 1 cm wide; sessile. Sepals 4, reflexed, ovate, 5-10 mm long, 2.5-4.5 mm wide; petals 4, 10-16 mm long, 7-11 mm wide; styles 7-9 mm long, stylopodium prominent. Capsules cubical, 4-angled, usually narrowly winged, appressed pubescent to glabrous, 5-7 mm long, 3.5-5 mm broad; bracteoles linear, 2-4 mm long; pedicels to 15 mm long."[2]
Distribution
L. virgata ranges from southeast Virginia to south peninsular Florida, and west to Panhandle Florida and southeast Alabama.[1]
Ecology
Habitat
This species can be found in moist areas along cypress swamps, pine flatwoods, hillside bogs, wet depressions in savannas, and around ephemeral ponds.[3] They thrive in moist sandy loam and can occur in open lit areas.[3] This species has also been observed in human-disturbed habitats such as along roadsides.[3] L. virgata does not respond to soil disturbance by clearcutting and chopping in North Florida flatwoods forests.[4]
Associated species include Cypress, Pinus, Rhexia, and Pteridium.[3]
Phenology
L. virgata flowers from May through September with peak inflorescence in June and fruiting from June through August.[3][5]
