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
In the Coastal Plain in Florida, L. sessiliflora occurs in longleaf pine-wiregrass communities, and pine-scrub oak barrens. It has been found in disturbed areas such as cutover pine communities, former live oak plantations and along railroad tracks (FSU Herbarium). Associated species include Dalea, Eupatorium, Liatris, Pityopsis, Symphotrichum, and Schizachyrium (FSU Herbarium). 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).
