Everglades palm, paurotis palm
Stems: Clustering, upright stems to 6 m tall and 5-15 cm in diameter, covered with old leaf bases and fibers that gradually fall with age. Leaves: Palmate, induplicate, with blade divided more than half its length by numerous, stiff, narrow segments. Upper leaf surface, bright green; undersurface, silvery; leaftips bifid. The petiole has a lobed hastula and is armed with robust teeth that curve upward or downward along both margins. Flowers and fruits: Inflorescences (ca. 1 m long) are branched to four orders and extend beyond the leaves. Flowers are small, creamy white and bisexual. Fruits are small (1-1.5 cm), spherical, at first orange then black when ripe.
Field: Erect, clustering fan palms found in or near brackish swamps; robust teeth along petiole margins.
Lab: Silvery scales on the underside of the leaf blade and visible transverse veinlets.
Serenoa repens: Acoelorrhaphe wrightii is erect with a much taller and more slender stem than the occasionally upright Serenoa repens. The marginal teeth of the Serenoa's petiole are much smaller. In addition, inflorescences of Acoelorrhaphe are longer than its leaves.
Native to Southern Florida and the Caribbean in low-elevation, easily inundated areas
Acoelorrhaphe wrightii has been described as both "palmate" and "minorly costapalmate." Look at the photograph of the intersection of the petiole with the leaf blade to see how the eyes of the beholder might influence this description.
