spreading, slightly cuneate at the base, concave, corrugated and puberu- 

 lous outside, glabi'ous inside, often retlexed, '5 in. long. Petals thick, 

 white, ovate-elliptic, sub-acute, hoarj-pubemilous except at the base 

 inside on both surfaces ; the outer row 1'5 to 3 in. long and "65 to 1 in. 

 broad, the inner row narrower. Stamens numerous, compressed ; the 

 apical process of the connective truncate, oblique, granular ; anther- 

 cells linear, dorsal. Ovaries 20 to 30, oblong, strigose, with a single 

 basilar ovule ; stigma oblong, pubescent. Bipe carpels elliptic, beaked, 

 1 in. or more long, hoary-pubescent, nai'rowed at the base into the short,

This resembles P. macrantha, King ; but is distinguished from it 

 by its cyniose, cauline inflorescence, smaller flowers and pubei^ulous 

 fruit. H. O. Forbes collected in the Lampongs in Eastern Sumatra a 

 plant (No. 1642 of his Herb.) which greatly resembles this. 



19. PoLYALTHiA iiTPOGAEA, King, n. sp. A ti'ce 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, 

 tomentose, Flowering branches from the stem near its base, 1 to 8 feet 

 long, flexuose, rufous-pubescent like the lanceolate bracteoles. Floivers 

 •75 to 1 in. long, cream-coloured; pedicels '75 to I'D in. long, usually 

 with one lanceolate, tomentose bracteole near the middle and a second 

 sub-orbicular and acuminate, close to the flower. Sepals broadly tri- 

 angular-ovate, acute, spreading, tomentose outside, glabrous inside, -25 

 in. long. Petals coriaceous, the inner 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- 

 ])ressed ; apical process of connective broad, slightly convex, slightly 

 oblique, sub-granular, deeply ridged in front, the anther-cells linear 

 dorsal. Ovaries few, oblong, villous, 1-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.
