Taxonomic notes
Synonyms: Lechea patula Leggett; L. exserta Small; L. prismatica Small.[1]
Varieties: none.[1]
Lechea species can be hard to distinguish from each other due to microscopic differences, often leading to problems with correct nomenclature.[2]
Description
Lechea sessiliflora is a herbaceous perennial distinguished from other Lechea species by having a conspicuously exserted, ellipsoid capsule that is capped by a reddish-brown fimbriate stigma.[3] The species in Lechea have a distinctive calyx with the two outer sepals very different in size and shape from the three inner sepals.[2] It is often mistaken for L. deckertii because both species have prominently exserted straw-colored capsules with persistent stigmas. The easiest way to distinguish these two species is by the length of the outer slender sepals and the shape of the capsules. L. sessiliflora has ellipsoid capsules and the narrow outer sepals are almost equaling or a little longer than the broad inner sepals.[3]
L. sessiliflora does not have specialized underground storage units apart from its taproot.[4] Diaz-Toribio and Putz (2021) recorded this species to have an non-structural carbohydrate concentration of 143.2 mg/g (ranking 45 out of 100 species studied) and water content of 46.7% (ranking 62 out of 100 species studied).[4]
According to Diaz-Torbio and Putz (2021), Lechea sessiflora has taproots with a below-ground to above-ground biomass ratio of 0.395 and nonstructural carbohydrate concentration of 143.2 mg g-1.[5]
Distribution
This plant ranges from southern North Carolina to southern Florida, then west to southern Mississippi.[1]
Ecology
Habitat
Habitats include longleaf pine-wiregrass communities, pine-scrub oak barrens, coastal scrubs, and dry pine flatwoods. It is found in disturbed areas such as cutover pine communities, sandy roadsides, former live oak plantations, and along railroad tracks. L. sessiliflora was found to decrease its occurrence in response to soil disturbance by agriculture in Southwest Georgia. It has shown resistance to regrowth in reestablished native savanna habitat that was disturbed by agricultural practices.[6]
Associated species include Dalea, Eupatorium, Liatris, Pityopsis, Symphotrichum, and Schizachyrium. Soil types include loamy sand and sand.[7]
Lechea sessiliflora is an indicator species for the Peninsula Xeric Sandhills community type and is frequent and abundant in the North Florida SUbxeric Sandhills community type as described in Carr et al. (2010).[8]
Phenology
L. sessiliflora flowers from July through August and fruits from August through October.[1]
Seed dispersal
This species is thought to be dispersed by gravity.[9]
Seed bank and germination
Kirkman found the vulnerability ratio for soil disturbance to be 3/3(reference sites/recovery sites).[10]
Pollination
The following Hymenoptera species were observed visiting flowers of Lechea sessiliflora at the Archbold Biological Station:[11]
Sweat bees from the family Halictidae: Lasioglossum placidensis
Conservation, cultivation, and restoration
Cultural use
