Diplazium subintegrum Holttum, Gard. Bull. S.S. 9: 125. 1940; Holtt.,
Gard. Bul. S.S. 11: 104. 1940. --- TYPE: R.E. Holttum SFN 31350 holotype, SING, S. Burong, Cameron Highland, Pahang, Malay Peninsula.
Rhizome short, erect. Stipe 59 cm long, 4 cm diam. when dry, scales; scales brown, entire, to about 1.5 cm by 2 mm. Lamina simply pinnate, 53,8 by
32 cm; pinnae 10 pairs, the apical lamina narrowly deltoid, lobed at the base; pinnae ca. 22 by 3 cm, lowest stalked to 1.5 cm, upper 2 pinnae only sessile;
bases almost equal, of lower pinnae narrower, cuneate, edges toothed, apices acuminate; texture softly chartaceous, glabrous; veins forked near the costa, the
upper branch always simple, the lower branch forked 1-4 times. Sori on upper branch from base 13-12 of way towards margin, diplazioid, usually also on one
branch only of lower vein, simple; indusia pale brown, thin, persistent. DISTRIBUTION. Malay Peninsula, Sumatra.
ECOLOGY. Terrestrial. In jungle, on humus rich soils, in deep shade in valley at first over 4000- 5000 ft. 1600-1800 m sea level

653 Holotype, BO. Rhizome stout, erect. Stipe ? long, end glabrescent, nearly glossy.
Lamina bipinnate; pinnae oblong lanceolate, shortly stalked to 9 mm long, 40 by 14 cm; rachis glabrous, nearly glossy; pinnules 17 pairs below acuminate deeply
pinnatified apex of pinnae, one basal pinnule a little reduce, acrossopic ones smaller than basiscopic, upper pinnule adnate to sessile with broadly cuneate base,
lower pinnules shorthly stalked to 2 mm long; larger pinnules to 8.2 by 1.9 cm, oblong subtriangular with sharply acuminate apex, base truncate, margin deeply
lodeb to within 0.5-1 of the costule; costule distinctly winged above, tomentose beneath, liniery small scales; lobes segments almost at right angle to costae,
basal basiscopic lobes the largest, oblong, to 12 mm long, 3.5 mm wide, apex obliquely rounded to acute with crenate tip, margin crenate ¼-23 way to
costulets; costulets distinctly winged above, tomentose beneath; veins pinnate in each segment 6-7 pairs, veinlets on larger lobes forked 1-2 times in each
crenation, one pair end simple, veinlets on smaller mostly simple. Sori elongate along veinlets a half or less length from costulets, on one pair basal ones usually
diplazioid; indusia pale brown, thin fragile, margin sharply toothed, crisped when opening.
SPORES. Monolete, bilaterally symmetrical made asymmetric by perine, heteropolar; polar outline excluding perine transversely elliptical, sides
convex-straight; equatorial longitudinal view excluding perine concave-convex; equatorial tranverse view, proximal face convex, distal face biconvex; perinate.
E: 32.4940.2947.17±4.08, P: 17.1521.5428.28±2.90. Laesura: concealed by perine ridge. Perine: alate, costate-alate, irregular envelope, reparated from exine;
costae or alae sometimes form loose reticulation; lacunae irregular polygons c. 3.3—12.5 µm, interior of lacunae smooth under SEM; muri, wing-like, smooth,
terminal margin entire. Exine: smooth under SEM.
269 ANATOMY. Transverse section of stipe near lamina: Vascular bundle
form an uninterrupted U-shaped with an angle 100º, angles ridges outward, end ridges outward and shallowly grooved.
CHROMOSOMES. 2n = 82 Cytotype: T.Ng. Praptosuwiryo 2292, BO. DISTRIBUTION. Java.
ECOLOGY. Growing on on humus rich soil rather opened places of secondary mountain forest.
