Inflorescences with 3 orders of branching (not counting main inflorescence axis), arching, equaling or exceeding leaves in length. Flowers 4.1--6.7 mm. Fruits black, spheroid, length 8--13.8 mm, diam. 8.1--13.9 mm. Seeds 4--7 mm, diam. 5.4--9.7 mm diam. 2n = 36.
Flowering spring--summer (northern part of range) or year around (southern part of range). Hammocks, pinelands, river banks, dunes, tidal flats; 0--40 m; Fla., Ga., N.C., S.C.; West Indies (Bahamas, Cuba).
Sabal palmetto grows in a variety of habitats, from pine and oak associations to coastal dunes and to coastal marshes (K. E. Brown 1976; S. Zona 1990). Like S. minor, it is polymorphic at the extremes of its range; however, differences in stature, size, and trunk characteristics are not of a magnitude to warrant taxonomic rank. In the pine rocklands of Dade County, Florida, S. palmetto may flower and fruit with little or no aboveground trunk.
Although Sabal palmetto is a moderately important honey plant, its greatest economic use is as an ornamental.
