long, 4 mm thick, light brown when dry, black and scales at base; scales lineary lanceolate, to ca. 9 mm long, 1 mm broad, black, shiny, margin toothed, with
regularly thickening black strands, teeth forked at tip. Lamina bipinate, deltoid, ca. 50 cm long and broad; lower pinnae stalked to 6.5 cm long, to 9 cm apart,
ascending, oblong subtringular, to 28 cm long, 12 cm broad, pinnulae to 13 pairs; lower pinnulae stalked to 2 mm long, upper adnate to sessile, lanceolate, to 7.5 cm
long, 2 cm broad, base truncate, apex sharply acuminate, margin lobed 23-34 way to costa; basal acroscopic lobes much reduce to 2 mm broad, larger lobes to 6
mm broad, oblique, broadest at base, apex truncate to rounded, entire; rachise not gemmiferouse; veins free, pinnate in the lobes, veinlets 6-7 pairs, commonly 7
pairs, simple or once forked. Texture thinly papyraceous. Sori medial, cover ¼- 34 of veinlets length; indusia thin, pale brown, persistent, margin laciniate.
DISTRIBUTION. Sumatra. ECOLOGY. Terrestrially, in primary forest at 900-1200 m.
NOTES. Diplazium meijeri may closely related to D. latisquamatum. D. meijeri
differs from D. latisquamatum in its black lineary toothed scales with regular thickening black strands; sori medial. D. latisquamatum has dark brown
round-ovate entire scales with irregularly thickening black strand; sori basalis. ETYMOLOGY. This species is named after W. Meijer, the collector of
this species.
