Description
"Perennial or annual herbs, stems erect, strict or freely branched. Leaves crenate, serrate or entire. Raceme terminal ,bracteate, often very leafy and the flowers appearing axillary. Calyx 5-lobed, more or less actinomorphic; corolla zygomorphic, fenestrate, 2-lipped, upper lip 2-lobbed, lower 3-lobbed. Stamens 5, completely united. Capsule dehiscent by apical pores. Seeds yellowish brown, tuberculate, oblong, 0.6-1 mm long." [1]
"Similar to L. elongata. Stems pubescent, at least near the base. Leaves elliptic, lanceolate or oblanceolate, 3-12 cm long, 1-4 cm wide. Calyx lobes lanceolate, rarely linear, 5-10 mm long, sometimes slightly auriculate, entire or with callous-tipped teeth; corolla tube 7-10 mm long; filament tube 5-8 mm long. Capsule 6-8 mm broad." [1]
Distribution
Ecology
Habitat
It is found in burned and unburned patches of degraded longleaf pine sandhill in the southeastern United States. [2] This species is also found in pine flatlands, boggy clearings, upland pine-oak woodlands, ravines, along limestone glades, and along riverbanks. [3] It can occur in dry, sandy soils, loamy soils, clays, and moist soils of wetlands in open to partial shaded areas. [3] L. puberula has also been found growing in human disturbed areas such as ditches and along roadsides. [3] Associated species include Pinus palutris, Quercus virginiana, Pinus echinata, Quercus falcata, Helianthus, Eupatorium, Agalinis, Liatris, Coreopsis gladiata, Juncus trigonocarpus, Scleria reticularis, Sphagnum, Pinus taeda, Aristida stricta, and Schoenus nigricans. [3]
Phenology
This species has been observed flowering and fruiting from August to December. [3]
Seed bank and germination
Several short-lived perennial forbs also have a seed bank persistent for at least several years. [4]
Fire ecology
This species thrives in areas that are burned. [3]
