This resembles P. macrantha^ King ; but is distinguished from it 
by its cymose, cauline inflorescence, smaller flowers and pubemlous 
fruit. H. O, Forbes collect L-d in the Lumpon^ in Eastern Sumatra a 
plant (No. 16 42 of his Herb.) which greatly resembles this. 
19. Poltalthia iiypogaea, King, n. sp. A tree 25 to 30 feet 
high ; young branches rather stout, densely but minutely rufous-tomen- 
tose, ultimately rather pale, striate. Leaves large, thinly coriaceous, 
oblong or elliptic-oblong, sometimes slightly obovate, gradually narrowed 
to the rounded base -, both surfaces glabrous when adult, the lower 
puberulous when young, the veins transverse and, (like the reticulations), 
distinct ; main nerves 18 to 22 pairs, oblique, inter-arching within the 
edge, thin, prominent on the lower and depressed on the upper surface 
when dry ; length 10 to 20 in. , breadth 3 to 7 in. ; petiole "4 in., stout, 
tomeutose, Flowering brandies from the stem near its base, 1 to $ feet 
long, floxuose, rufous-pubescent like the lanceolate bracteoles. Flowers 
*75 to 1 in. long, cream-coloured ; pedicels '75 to 1*5 in. long, usually 
with one lanceolate, tomentoso bracteole near the middle and a second, 
sub-orbicular and acuminate, close to the flower. Sepals broadly tri- 
angular- ovate, acute, spreading, tomcntose outside, glabrous inside, '25 
in. long. Petah coriaceous, the innor row rather smaller than the outer, 
narrowly oblong, sub-acute, pubescent outside except the glabrescent 
base and edges, inside almost glabrous. Stamens numerous, short, com- 
pressed ; apical process of connective broad, slightly convex, slightly 
oblique, sub-granular, deeply ridged in front, the anther-cells linear 
dorsal. Dearies few, obloug, villous, J-ovuled ; stigma large, ovoid, 
granular, sessile. Immature carpels narrowly ovoid, sub-compressed, 
the apex beaked, the base slightly contracted, minutely tomentose. Seed 
solitary, elongated, ovoid, smooth.
