Taxonomic notes
The genus Serenoa honors Sereno Watson, an assistant of Asa Gray. Repens refers to the plant's creeping habit[1].
Description
A description of Serenoa repens is provided in The Flora of North America.
S. repens has been observed to have no true stem, with petiole spinescent below surface[2].
Distribution
This species is distributed from South Carolina to southeastern Louisiana[3]. It is one of the most abundant species in Florida[1]. Typical individuals have green leaves, however, there is a form with blue leaves that can be found along the southeastern coast of Florida[4].
Ecology
Habitat
In the Coastal Plain in Florida and Georgia, Serenoa repens has occurred around sinkholes in oolite, on dunes in an understory of Pinus clausa, sandpine-evergreen oak scrubs, cabbage palm-hardwood hammocks, pine flatwoods, open slashpine woodlands, coastal hammocks, Baccharis flats, longleaf pine-scrub oak ridges, dried up ponds, and pine-oak woodlands. It has been found in disturbed areas such as open pastures, roadsides, and a newly planted slash pine plantation with deep sterile sandy soil[2]. It will occur on sites ranging from xeric to hydric and on soils ranging from strongly acidic to alkaline[5] and has been found on sandy loam and sand[2]. Associated species include Persea, Rapanea, Myrica, Ficus, and Ardisia [2].
Phenology
S. repens reproduces vegetatively by sprouting from rhizomes and sexually[6]. It flowers March through June and fruits April through December[2].
Seed dispersal
Seed bank and germination
Fire ecology
S. repens has been observed growing in burned turkey-oak pinewoods and recently burned longleaf pine-turkey oak sandhill (FSU Herbarium).
