Description
This species can be frequent where it occurs. [2]
"Perennial herbs with tap roots and basal rosettes of procumbent, leafy stems late in the season; early stems erect, several from a crown, freely branched above, appressed or spreading pubescent. Leaves opposite, subopposite, whorled or subverticillate on lower part of stem, usually alternate above, usually short-petiolate; leaves of the winter rosettes usually whorled or subverticillate. Inflorescence of scroppoid cymes or racemes in a panicle or theyrse. Sepals 5, outer 2 linear, inner 3 elliptic to ovate; petals 3, reddish or maroon, usually shorter than the sepals; stamens mostly 5-15; stigmas 3, red, plumose. Capsule 1-3 seeded; seeds reddish brown or brown ca. 1 mm long." [3]
"Stems appressed pubescent, 2-7 dm tall with mostly spreading ascending branches; principal stems 1-2 mm in diam. Leaves oblong to elliptic, spreading to spreading-ascending, 6-12 mm long, 1-3 mm wide, glabrous above, ciliate, pubescent beneath mostly on the midrib and near the margins; leaf arrangement similar to no. , but opposite and whorled arrangement often higher into the inflorescence; petioles ca. 1 mm long. Inner sepals shorter than the capsule, 1-1.5 mm long, outer slightly longer. Capsule ellipsoid 1.2-1.7 mm long, 0.7-1 mm broad, 3-seeded." [3]
Distribution
Ecology
Habitat
This species can be found in sandy soils in open fields, open bogs, and longleaf pine forests. [2] It also occurs in human disturbed areas such as powerline corridors and in old roadbeds. [2] Associated species include Longleaf pine and wiregrass. [2]
Lechea minor is an indicator species for the Clayhill Longleaf Woodlands community type as described in Carr et al. (2010).[4]
Seed dispersal
This species is thought to be dispersed by consumption by vertebrates. [5]
Seed bank and germination
Several short-lived perennial forbs also have a seed bank persistent for at least several years.[6]
Fire ecology
Can grow in areas that are annually burned. [2]
