long; the claw short, thickened, pubescent on both surfaces like the sepals. Stamens
numerous; the connective with an apical process which is bulbous at the base and
suddenly tapers into a sharp point. Ovaries numerous, cohering into a mass, oblong,
glabrous except at the pubescent base, with 6 or 8 ovules in two rows,; stigma sessile,
truncate, liipe carpels unknown.
Perak,—Scortochini.
Scortechini's specimens are in bud only and none of i hem has any fruit. The
foregoing description has been prepared partly froiu. his notes and partly from his
vsperimens. The species diSors from 0. odoratum in having smaller leaves, a difEerent
inflorescence, with smaller and quite inodorous flowers. It is also a smaller tree.
