1-8 to 2-6 i n . ; petiole - 2 5 , t o -35 in. Flowers- about 1 iu. long, in clusters of 20 to
RO from nodulated pubenilous tubei-oles on the stem; pedicels long (l-o to 2-5 in.),
slender, pubenilous, -with an ovate-lanceolate .bracteoie about the middle. Sepah thick,
lanceolate-acuminate with broad connate bases, sub-eroct, puberuloiis. Petals coriaceous,,
sub-erect, linear-oblong, slightly concavc ami ^ilabrous at the base inside, otherwise
minutely tomentose; the inner slightly smaller than the outer. Stamens numerous; the
coimective ^rith an orbicular, sub-convex, apical expansion concealing the linear dorsal
anther-cells. Ovaries much less numerous than the stamens, oblong, hirsute, apparently
1-ovulcd ; the stigma small,. oblong, slightly pubescent.

Distrib.—Sumatra,—JbrScs (No. 280-t).
I n all the flowers I have examined the pistils are very small (as if undeveloj)od),
and I have not been able to find more than one ovule. In the Sumatran specimens
t h e flowers are much longer than in those from . Perak.

base concave, corrugated and puberulous outside, glabrous inside, often reflexed, '.3

base inside on both surfaces: the outer row 1'5 to 3 in. long and '65 to 1 in. broad,

connective truncate, oblique, g r a n u l a r ; anther-cells linear, dorsal. Ovaries 20 to 30,
oblong, strigose, with a siogle basilar ovule; stigma oblong, pubescent. Ripe carpeb

This resembles P. macrantha, King ; but is distinguished from that by its cytnose,
cauline inflorescence, smaller flowers and puberulous finait. Mr. H. 0 . Forbes collected in
t h e Lampongs in Eastern. Sumatra a plant (No. 1G42 of his Kerb.) which greatly
resembles this.
