Scientific Name:

Acrostichum aureum L.
Description:

Species Description - Rhizomes short-creeping, branched, massive; rhizome scales linear to ovate, dark brown, to 1.5 cm long; fronds 1.5–3 m long; stipes ca. 1/3 of the frond length, terete to decidedly grooved distally, short spines (aborted pinna midribs) frequent on distal stipe; pinnae 10–14(–30) pairs, obtuse to acute at apices, coriaceous, overlapping, margins recurved; proximal pinnae with stalks to 3 cm long; costal areoles narrow, 3 times longer than wide, extracostal areoles divergent from costae at 45–60° fertile pinnae 1–5 pairs in distal portion of blades, similar in size and shape to the sterile pinnae; paraphyses each with isodiametric, multilobed tip; 2n=60 (Jam).

Discussion:

Lectotype (chosen by Lellinger, 1985: Proc. Biol. Soc. Wash. 98: 366). Plumier, Descr. Pl. Ame´r., pl. 7, 1693, based on a specimen collected by Plumier at F. Royal, Martinique; LINN 1245.5 was not present in LINN prior to 1756 (Jackson, 1912). Acrostichum aureum is restricted to coastal saline mangrove communities. It is distinguished from A. danaeifolium by the former being fertile only in the distal 1/4–1/3 of the blades (rather than nearly the entire length).
