Arbor circiter 20 m alta, partibus junioribus leviter ferrugi- 
neo-pubescentibus exceptis glabra; foliis ellipticis ad obovato- 
ellipticis, coriaceis, usque ad 7 cm longis, in siccitate pallidis, 
subtus puncticulatis, apice rotundatis, basi decurrento-acumina- 
tis; floribus flavis, cum staminibus circiter 2.5 cm longis, in 
axillis superioribus vel inflorescentiis racemosis efformantibus. 
A tree about 20 m high, glabrous except the more or less 
ferruginous-pubescent young branchlets. Branches terete, red- 
dish-brown. Leaves alternate, crowded toward the ends of the 
branchlets, elliptic to obovate-elliptic, coriaceous, pale and some- 
what shining when dry, 4 to 7 cm long, 2.5 to 3.5 cm wide, 
apex rounded, base decurrent-acuminate, the lower surface glan- 
dular-punctate; lateral nerves about 10 on each side of the midrib, 
slender; petioles up to 1 cm in length. Flowers in the upper- 
most axils and forming terminal racemes, yellow, their pedicels 
about 1 cm long. Calyx-tube cup-shaped, about 5 mm long and 
8 mm in diameter, the lobes 5, reniform, about 2 mm long and 4 
to 5 mm wide, their margins minutely ciliate. Petals 5, subor- 
bicular, rounded, 7 to 8 mm in diameter. Disk very prominent, 
lining the perianth-tube, about 8 mm in diameter, distinctly 
projecting beyond the insertion of the filaments. Stamens about 
24, their filaments about 15 mm long. Ovary superior, ovoid,

Luzon, Camarines Province, Paracale, For. Bur. 24812 de Mesa, Nov- 
ember 30, 1915, altitude about 40 meters, locally known as odkacanala. 
A very characteristic species, at once distinguished from Xanthostemon 
verdugonianus Naves by its larger yellow flowers and its prominent disk. 
In vegetative characters the two species are very similar.

teis multis lanceolatis foliaceis instructis; floribus albidis, circiter 
3.5 cm diametro, 5-meris, petalis orbiculari-obovatis, sepalis 
ovato-lanceolatis, acuminatis, staminibus circiter 25; capsulis 1 
cm diametro, 3-locellatis, 3-valvatis. .
