Taxonomic notes

Lechea species can be hard to distinguish from each other due to microscopic differences, this often leads to problems with correct nomenclature (Barringer 2004).

Description

L. 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 [1]. The species in Lechea have a distinctive calyx with the two outer sepals very different in size and shape from the three inner sepals (Barringer 2004). 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[1].

Distribution

Ecology

Habitat

Habitats include longleaf pine-wiregrass communities, pine-scrub oak barrens, coastal scrubs, and dry pine flatwoods. It has been found in disturbed areas such as cutover pine communities, sandy roadsides, former live oak plantations and along railroad tracks. Associated species include Dalea, Eupatorium, Liatris, Pityopsis, Symphotrichum, and Schizachyrium. Soil types include loamy sand and sand (FSU Herbarium).

Phenology

L. sessiliflora has been observed flowering August through October and fruiting in October (FSU Herbarium).

Seed dispersal

Seeds are dispersed by gravity (Kirkman et al. 2004).

Seed bank and germination

Kirkman et al. (2004) found that the vulnerability ratio to soil disturbance is 3/3(reference sites/recovery sites).

Fire ecology

Pollination

The following Hymenoptera families and species were observed visiting flowers of Lechea sessiliflora at Archbold Biological Station (Deyrup 2015):

Halictidae: Lasioglossum placidensis
