Description
"Perennial or annual herbs with erect stems that are 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."[2]
"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."[2]
Distribution
L. puberula ranges from New Jersey, southeast Pennsylvania, southern Ohio, southern Indiana, southern Illinois, southeastern Missouri, Arizona, and Oklahoma, south to peninsular Florida and southern Texas.[1]
Ecology
Habitat
It is found in burned and unburned patches of degraded longleaf pine sandhill in the southeastern United States.[3] This species is also found in pine flatlands, boggy clearings, upland pine-oak woodlands, ravines, along limestone glades, and along riverbanks.[4] It can occur in dry, sandy soils, loamy soils, clays, and moist soils of wetlands in open to partially shaded areas.[4] L. puberula is also found growing in human-disturbed areas such as ditches and along roadsides.[4] 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.[4]
Lobelia puberula is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[5]
Phenology
L. puberula flowers from July through October.[1]
Seed bank and germination
Several short-lived perennial forbs also have a seed bank persistent for at least several years.[6]
Fire ecology
This species thrives in burned habitats.[4]
Herbivory and toxicology
Lobelia puberula has been observed to host bees from the Apidae family such as Bombus fervidus and Xylocopa virginica.[7]
