224 provided with minute and remote incision on margin, 4 venation obscure,
acroscopic veinlet of group simple and soriferous, basiscopic one once forked and sterile, 5 sori all asplenioid, narrower, very unequal in length, their anterior ends
arranged in an intramarginal uneven line, 6 scales at the base of stipe much longer.

Diplazium insigne Holttum, Gard. Bull., S.S. 9: 123. 1937; Holttum,
Gard. Bull. S.S. 11: 87. 1940. --- TYPE: R.E. Holttum SFN 21635 holotype, SING, Trans Valley, Frasser’s Hill, Pahang, Malay Peninsula.
Rhizome stout, short, erect. Stipe stout, c.1 m long, spiny toward the base, the spines 2 mm long, each at first bearing a scale; scales dull brown 1.5 cm long
by 1.5 cm wide at base, with a narrow black toothed edge, deciduous. Lamina to 1.5 m long, bipinnate; lowest pinnae about 28 cm long and 6.5 cm wide, narrowed
and stalked at the base, the margins lobed half-way to the costa, the apex acuminate; middle pinnae largest, to 60 cm long and 16 cm wide, pinnate;
pinnules slightly oblique, adnate to the rachis the lowest ones narrowly, the upper fully adnate and grading into the lobed apical lamina of the pinna, to 9 cm long
and 2.3 cm wide, cunete at the base at an angle of about 45o on each side, narrowed gradually from the base and then suddenly at 1.5 – 2 cm, from the apex,
margins slightly serrate; texture firmly herbaceous; veins anastomousing as in D. accedens.
Sori few or copious, the lowest acroscopic sorus in each vein-group usually diplazioid, and occasionally a few others also.
ECOLOGY. In moist shady valley forest. 600-1200 m DISTRIBUTION. Malay Peninsula.
SPECIMENS EXAMINED. --- MALAY PENINSULA: R.E. Holttum SFN 21635.
NOTES. As stated by Holttum 1940 this species is evidently closely allied to D. accedens and the apex of afrond might pass for that species, but its
copious bipinnate form marks it as a quite distinct species. Holttum 1940 added that this species is also similar to D. Smithianum from Ceylon, but appears to be
225 much larger; probably both D. Smithianum and D. insigne are local derivatives of
D. accedens or D. proliferum.

Athyrium kunstlerii Holtt. Holttum, Rev. Fl. Malaya 2: 564. f. 335. 1966. ---
TYPE: R.E. Holttum SFN 31194 holotype, US. Rhizome suberect, about 2 cm diam., scales on younger part. Stipe 7 mm
diam at base, 70 cm long, glabrescent, dark brown, nearly black and scales at base; scales rounded. Lamina bipinnate, about 107 cm long, 60 cm wide; pinnae
about 11 pairs; larger pinnae 52 cm long, about 16 cm wide, on stalk to 11 cm long, upper pinnae with shorter stalk; lowest pinnules to about 5 cm apart, largest
ones 9.2 cm long, 2.7 cm broad, on stalk to 2 mm long, base broadly cuneate to truncate, margin lobed to 23 way toward costa; lobes slightly oblique, 5-7 mm
wide, base dilated, margin slightly toothed, apex rounded; texture thicker than in allied species; rachis gemmiferous at upper portion; veins in each lobe 6-9 pairs,
oblique, mostly simple, distinct but hardly prominent on both surface. Sori at middle part of the veins or nearly close the costules, basal acroscopic veinlets
usually diplazioid; indusia narrow, hardly evident in mature sori, very dark brown. DISTRIBUTION. Malaya, Java.
ECOLOGY. Locally abundant near streams in shady forest in the foothills. Ca. 900-1000 m.
