Flora of the Malayan Peninsula. 437 
obscure, 12—15 pairs, nearly straight to near the margin and there 
joined by somewhat angular loops, secondary nerves few; transverse 
nervules very irregular much branched enclosing the minutely areo- 
late but obscure reticulation; petiole slender, 5—10 mm. long, occa- 
sionally (Sumatran specimens) longer, the upper part bordered by the 
decurrent margins of the blade. Spikes usually under 10 cm. long, 
slender, axillary or the 3 in sparse terminal panicles, the 9 solitary 
in lower axils; rhachis of # very slender, angular, grey-pubescent, 
of 2 stouter; bracteoles very minute, ovate-acute. Flowers: 3 in 
glomerules of about 3, rarely solitary ; perianth cup-shaped, small 
scarcely 1 mm. long, lobes 6, puberulous, ciliate on the margins; 
stamens 10, filaments slender, anthers globose; pistillode large, very 
villous, white when dry; 2 solitary, sessile, cupule obscurely ringed ; 
perianth-lobes asin & but smaller; styles 3, very short. Fruzt in 
spikes up to 10 em. long, solitary, sessile ; cupules obconic below, 
saucer-shaped above and quite shallow, thin, 10—12 mm. broad, 
3—5 mm. high; when quite young embracing the whole acorn, when 
ripe its base only, the edges acute, spreading ; lamellae 4—6, seri- 
ceous, when quite young denticulate, when old entire broad and 
thickened ; acorn ovoid-conic, smooth and shining, glabrous except 
just around the umbo, 15 to nearly 20 (var.? montana, Hook. £.) mm. 
in diam. and height, the base much intruded; umbo conic, sharp.

The variability of this species is noticed in the Fl. Br. Ind. and it may be 
well here to call attention to Ridley’s remarks on the subject in his paper on 
‘New and rare Malayan Plants’ in Journ. Str. By. R. As. Soc. No. 61 (1912), 
p. 36. His No. 12061 from Ulu Semangkoh mentioned in the same paper has 
much thicker and differently-shaped leaves and is probably a new species.
