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."[2]
"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."[2]
"Leaves 0.8-5 mm wide. Branches of inflorescence ascending. Inner sepals are densely glandular serrulate. Capsule ovoid, 2-3 mm long."[2]
Distribution
L. floridanum var. chrysocarpum ranges from southeast North Carolina, south to southern Florida, and west to southern Mississippi. L. floridanum var. floridanum has a similar range, except it is additionally located in Lousiana and the West Indies.[1]
Ecology
Habitat
This species can be found in open wiregrass seepage savannas, longleaf pine forests, and disturbed areas such as ditches.[3] The soils have been observed to be moist and/or dry loamy sands within well-drained uplands.[3] Associated species include Pinus palutris, Aristida stricta, Sarracenia, and Harperocallis.[3]
Phenology
L. floridanum flowers from June through October.[1]
Seed dispersal
This species is thought to be dispersed by gravity.[4]
Fire ecology
This species occurs in areas that are annually burned.[3] In an open wet pine savanna in Mississippi, the highest densities of flowering stalks for L. floridanum were observed one year after fire.[5]
