Notes

Acrostichum aureum is a fern with erect rhizome and fronds in clumps. Young fronds are entire while adults are pinnate, measuring 1 to over 2m in length. The petiole is 30-50 cm long, rigid and naked. The leaf blade is oblong-lanceolate, about 50 cm to 2 m long, with lanceolate pinnae. The pinnae are 20-30 cm long for 3-5 cm wide, alternate, spaced about 3 cm, with cuneate-oblique base. The upper pinnae are sessile while basal pinnae are stalked (Fig. 4a). Fertile pinnae are slightly narrower and completely covered by sporangia on their underside (Fig. 4b). This fern grows in the backward of mangroves, forming almost impenetrable bushes.
