On all bathyphylls seen (smallest 4 cm long) all pinnae articulate; largest seen 12 cm long with 6 pairs pinnae and stipe nearly 2 cm long; pinnae 10 by 5 to 30 by 12 mm, base narrowly cuneate on basiscopic side, broadly on acroscopic, edges crenate, apex blunt; on one collection most pinnae deeply lobed. Adult rhizome smooth. Sterile acrophylls to 40 cm long; rachis usually reddish when dry; pinnae stalked (stalk of lowest 3-4 mm), 5-9 cm long, 1.5-2 cm wide, basal pinnae with symmetric base, rest with base very unequal (basiscopic narrowly cuneate, acroscopic subtruncate), tapered gradually from widest part near base to acuminate apex, texture thin, edges in most cases distinctly crenulate (one crena to each vein-end). Fertile fronds shorter than sterile, pinnae 4.5-5.5 cm long, 5-7 mm wide.
