ovate obtuse bracts; the bracts, pedicels, and calyx-tube densely ferru- 
ginous-pubescent, the calyx-lobes less densely: calyx of staminate flowers 
divided nearly to the base into 5 triangular-ovate lobes 2 mm long, often 
3-veined ; petals 5, oblong-oblanceolate, about 1 mm long, the apex 
rounded or subtruncate, only obscurely sinuate; disk rather thin, with 
a free truncate rim, undulate in vertical view; androphore seen up to 
1.3 mm long; filaments 5, 0.5 mm long; anthers ovate, cordate, 0.7 
mm long ; rudimentary ovary elliptic or nearly oblong in outline, showing 
by difference of color or slight enlargement traces of a stylar portion, 
the latter most obscurely 4-lobed : calyx of pistillate flowers 2.5 mm long, 
acuminate; petals oblong; disk nearly covering the ovary, 10-lobed on 
the margin nearest the styles ; ovary ovoid, glabrous, minutely tuberculate, 
1 mm long, containing 2 cells each with 2 ovules ; styles 2, very shortly 
united at the base, free for about 1 mm, thence bifurcate for about 0.5 
mm, the arms curved or one in each pair straight. 
A tree 7 m high, its trunk-diameter 10 cm ; the bark of the branches 
purplish, scaly, marked by lenticels, bark of the branchlets yellowish or 
reddish, the very youngest parts slightly pubescent, elsewhere glabrous: 
petioles 7 to 9 mm long; lamina when dried thinly chartaceous, oblong- 
lanceolate, broadly lanceolate, or nearly elliptic, 7 to 15 cm long, 3 to 6 
cm wide, nearly equilateral, the base obtuse, the margins slightly sinuate, 
the' apex contracted, usually very gradually, into an acute or subobtuse 
acumen, more often about 15 mm long, but with about 10 mm variation 
on either side, upper surface shining, glabrous, under surface paler, 
minutely but densely pubescent; pairs of veins 8 to 11, slender, connected 
by numerous transverse veins, these evident on both surfaces, the finer 
venation evident on the under only.

growing at low elevations, used for posts. The specimen has very great similarity 
in general appearance to C. myrianthus Kurz, but the floral characters cited seem 
to prevent its inclusion in that species. Even very immature flowers are pedicelled, 
occasional minute ones are not; the number of styles was constant in 10 flowers l 
examined for the purpose, and all of these were in good condition, so. that it was 
possible to be certain that this was not the result of mechanical injury. With 
this is correlated the difference in the ovary, and perhaps that in the rudimentary 
ovary. 
Local name: sacatan. 
Cleistanthus pilosus sp. nov. 
Arbor, ramulis dense ferrugineo-pilosis : floribus ignotis ; capsulis 
distanter spicatis, bracteatis, 3-locularibus, triangulari-rotundatis, in sin- 
ubus dense aliter laxiuscule pilosis : foliis brevissime petiolatis, chartaceis, 
oblongo-lanceolatis vel oblongis, basi emarginatis, apice obtuse acuminatis, 
venis utrinque 8 vel 9. 
Fruiting calyces sessile on ferruginous-pilose lateral branches 2 to 3 
cm long, surrounded by ovate, acuminate, pilose bracts ; calyx 4 to 5 mm
