apex, where it forms two lateral ol>tuse lobes and a short acute apical 
tooth, narrowed into a conspicuous claw at the l)ase: male flowers with 
a disk covering tiie ])ase of the calyx-tube and free for a very short 
distance, the and T-ogynophore developing Avith a^e, attaining a lengtli 
of 2 mm, the 5 filaments widely spreading from its apex, gradually- 
decreasing in thickness irpwards, 1 nnu long; anthers attaclied above 
tJie middle of the back, 1 jum long, 0.7 mm wide, cordate at the base, 
the cells diverging Aery slightly; rudin\ent of the ovary at the apex of 
the androgvnophore, 1.3 mm long, lanceolate: female flowers with a 
thin disk attached to tiie calyx for about 0.7 mm, azid then free for 1 
mm, its upper margin with a conspicuous tooth opposite each of the 
calyx-lobes and some smaller intervening ones; "ovary ovoid, glabrous, 
1.5 mm long, narrowed at the apex to a neck bearing 3 styles 1 mm 
long, which divide into 2 blunt anns for an additional 0.5 mm; ovary 
3-cellcd, each cell containing 2 ovules which are ovate in outline, 0.5 
mm long and 0.2 mm wide in diameter. 
A glabrous tree 18 m high, with a trunk 20 em in diameter, its bark 
reddish-brown, somewhat flaky, that of the ultimate branches brownish 
with scattered lenticels; leaves alternate, the petioles 0-8 mm long, the 
lamina coriaceous, entire, lanceolate or narrowly elliptic, 9-14 cm long, 
2.5-^.3 cm wide, the margins slightly revolute at the acute base, gradually 
narrowed from the middle and prolonged for 2-2.5 cm into a slender 
apiculate acumen, sometimes merely acute on one side and then slightly 
falcate, the upper surface olivaceous, the lower surface brownish-green, 
both surfaces shining, the upper especially; pairs of primary lateral veins 
9-11, both they and the finely reticulated secondary venation conspicuous 
on both surfaces, but the midrib much more prominent on the lower.

All three of the specimens cited have somewhat immature flowers and no 
capsules, but agree fairly closely in vegetative characters. The greatest dif- 
ficulty in this identification is the real identity of Cleistanthus mi/rianthus. 
Nanopcfalinn myrianthum is described as having leaves from the uoiite base 
oblong or oblong-lanceolate acuminate, larely acute or obtuse, and a specimen 
fr(mi it tree cultivated at the Buitenzorg Garden agrees with this description. 
In Kurz*s original description the loaves are said to l>e oblong to oblong- 
lanceolate, obtuse at the base, more or less acumiuutc. But Tbntker in the Flora 
of British India says that tbey are narrowly lineav-lanceulate acuminate base 
acute. These latter descriptions are entirely inconsistent, and it seems most 
improbable that Kurz and Hooker can have had the same spi'tii's in view. The
