EXCOECARIA PH I LI PPI N ENSIS Merr. var. EUPHLEBIA var. nov. 
Very similar to the type in all essential characters, differing chiefly in 
its much more prominent lateral nerves. In Excoecaria philippinensis 
the primary nerves are scarcely more prominent than are the secondary 
ones, while in the present form on the lower surface they are raised and 
very much more prominent than the secondary ones. In the shape of 
the leaves, their variation in form and size, texture, and in the flowers 
and fruit so far as our material shows, the variety appears to be quite 
the same as the species.

Bur. Sci. 13973 (type), 7^78 Ramos. Two specimens from Benguet Prov- 
ince may be referable here, but they have fewer nerves than the Cagayan 
material. Bur. Sci. 25 lU Meams and Bur. Sci. 13502 Ramos. Similarly 
two specimens from Tayabas Province differ, Whitford 773 and Bur. Sci,

EXCOECARIA OBTUSA sp. nov. 
Frutex glaber; foliis oblongo-obovatis, subcoriaceis, usque ad 
12 cm longis, apice late rotundatis, basi acutis, nervis utrinque 
10 ad 12, patulis, anastomosantibus, distinctis, margine recur- 
vatis; inflorescentiis $ in axillis superioribus, densis, quam 
petioli vix longioribus, floribus brevissime pedicellatis, brac- 
teolis reniformibus, rotundatis. 
A glabrous shrub. Branches terete, brownish or olivaceous 
when dry. Leaves subcoriaceous, oblong-obovate, 8 to 12 cm 
long, 3,5 to 6.5 cm wide, shining, the lower surface considerably 
paler than the upper, the apex broadly rounded, more or less 
narrowed below the middle to the acute base, margins recurved ; 
primary nerves 10 to 12 on each side of the midrib, spreading 
at nearly right angles, distinct, anastomosing and forming a 
looped marginal nerve, the secondary nerves about as prominent 
as the reticulations; petioles 1.5 to 2.5 cm long. Male racemes 
in the upper axils, solitary, shorter than the petioles, densely 
many-flowered, the rachis stout, the pedicels 1 to 1.5 mm long, 
the axillary glands prominent; bracteoles reniform, rounded, 
about 1.5 mm wide, 1 mm long, obscurely glandular on the 
margins. Sepals broadly ovate, acute, slightly glandular on the 
margins, 1 mm long. Filaments 1 to 2 mm long. Female 
flowers and fruits not seen. 
Luzon, Province of Cagayan, Abulug River, in forests near Dabba, Bur. 
Sci. 13917 Ramos, January, 1912, flowers yellow. 
A species manifestly allied to Excoecaria philippinensis Merr., but dis- 
tinguished at once by its very differently shaped, broadly rounded, not 
acute or acuminate leaves.
