Description

"Annual, biennial, or short lived perennial herbs with 1-several strict stems from a crown, usually branched above. Leaves cauline, opposite or alternate, entire, acute to acuminate, sessile, exstipulate. Inflorescence a panicle of racemes or cymes. Flower perfect, actinomorphic, pedicellate; sepals 5, separate or basally adnate; pistil 5-carpellate, styles 5, each carpel divided at maturity, the pistil then appearing 10-carpellate. Seeds lustrous brown, obovoid to ellipsoid." [1]

"Perennial with 1-several stems 3-8 dm tall, from a crown. Leaves mostly alternate, lowest often opposite, narrowly elliptic to linear, 0.8-2.5 cm long, 1-7 mm wide, acute. Pedicels 1-3 mm long. Sepals lanceolate, 2-3 mm long, acute to acuminate, entire or glandular serrate; petals yellow, 4-8 mm long. Capsule ovoid or oblate, 1.3-3 mm long. Seeds 1-1.3 mm long." [1]

"Leaves 0.8-5 mm wide. Branches of inflorescence ascending. Inner sepals densely glandular serrulate. Capsule ovoid, 2-3 mm long." [1]

Distribution

Ecology

Habitat

This species can be found in open wiregrass seepage savannas, longleaf pine forests, and disturbed areas such as ditches. [2] The soils have been observed to be moist and/or dry loamy sands within well-drained uplands. [2] Associated species include Pinus palutris, Aristida stricta, Sarracenia, and Harperocallis. [2]

Phenology

L. floridanum has been observed flowering in June and July.[2][3]

Seed dispersal

This species is thought to be dispersed by gravity. [4]

Fire ecology

This species occurs in areas that are annually burned. [2] In an open wet pine savanna in Mississippi, the highest densities of flowering stalks for L. floridanum were observed one year after fire. [5]
