the same color on both surfaces when dry, dull or slightly shin- 
ing, more or less verruculose, 9 to 11 cm long, 4 to 7 cm wide, 
the apex abruptly and shortly blunt-acuminate, base acute to 
rounded ; lateral nerves about 7 on each side of the midrib, rather 
prominent on the lower surface and here more or less hirsute. 
Inflorescence axillary, solitary, spike-like, simple, up to 10 cm 
long, the flowers more or less fascicled, their pedicels 2 mm 
long or less. Flowers white, 4-merous. Calyx shallow, about 
4 mm in diameter, obscurely 4-toothed, puberulent. Petals 4, 
oblong, puberulent externally, about 7 mm long, 3 mm wide. 
Staminal tube cylindric, glabrous, free, obscurely crenulate, about 
6 mm long; anthers 1.2 mm long, oblong, included. Disk free, 
glabrous, somewhat crenulate, about 2 mm long. Ovary ovoid, 
4-celled, puberulent; style 4 mm long, puberulent below, nearly 
glabrous upward. 
Luzon, Province of Laguna, San Antonio, Bur. Sci. 20512 Ramos (type), 
March 3, 1913, in forests. Bur. Sci. 20538 Ramos, same locality and date 
is probably referable to the same species, but its leaves are smaller and 
very slightly hirsute or nearly glabrous beneath, while the racemes are 
shorter. 
This species approaches Dysoxylum wenzelii Merr. in many characters, 
but it is quite different in its leaves. It is in the alliance with Dysoxylum 
vrieseanum C. DC., but is entirely different from the other species placed 
here.

Arbor glabra, vel foliolis junioribus leviter pubescentibus ; 
foliis alternis, usque ad 60 cm longis, foliolis circiter 15, oblongis 
ad oblongo-lanceolatis, acuminatis usque ad 19 cm longis, nervis 
utrinque circiter 15 ; racemis brevibus, paucifloris, caulinis, e 
tuberculis magnis; floribus circiter 1.7 cm longis, 4-meris, tubus 
stamineus liber, ovario dense villoso, petalis extus leviter 
pubescentibus. 
A tree about 8 m high, quite glabrous except the young leaflets 
which are sparingly pubescent. Branches terete or somewhat 
compressed, pale-brownish, the ultimate ones 5 to 7 mm in diam- 
eter. Leaves alternate, up to 60 cm long. Leaflets about 15, 
oblong to oblong-lanceolate, chartaceous, greenish or brownish 
when dry, quite glabrous, 9 to 19 cm long, 2.5 to 6 cm wide, 
the apex more or less acuminate, base obtuse, often somewhat 
inequilateral ; lateral nerves about 15 on each side of the midrib, 
in younger leaves somewhat pubescent. Racemes few r flowered, 
3.5 cm long or less, from large woody tubercles on the trunk, 
usually but 3 or 4 flowers in each raceme. Flowers 4-merous, 
about 1.7 cm long, their pedicels about 13 mm in length, glabrous.
