that warrant the recognition of two distinct species, and accordingly refer 
Cuming 1776 to Semecarpus philippinensis Engl. In degree of distinctness 
the ultimate reticulations in the two specimens differ considerably, and by 
Engler are accordingly placed in different sections in his key to the species. 
This character, however, is not at all constant, and all intergrades occur. 
I refer to Semecarpus philippinensis Engler the following material:

In this material the leaves vary in shape and size, the tip in the type 
being rounded or obtuse, in some leaves subacute, but in other specimens 
it varies to acute or acuminate.

SALACIA L. 
SALACIA PHILIPPINENSIS sp. nov. 
Frutex scandens, glaber; foliis oppositis, oblongis, coriaceis, 
nitidis, usque ad 15 cm longis, basi acutis, apice obtusis vel late 
obscure acuminatis, margine subintegris vel leviter crenatis; 
inflorescentiis cymosis, dichotomis, pedunculis quam petiolo long- 
ioribus ; floribus circiter 8 mm diametro. 
A scandent shrub, glabrous, the branches slender, terete, dark- 
colored when dry, with numerous small lenticels, the younger 
ones somewhat compressed. Leaves opposite, oblong, coriaceous 
or subcoriaceous, 12 to 15 cm long, 5 to 6 cm wide, shining, 
when dry the lower surface a little paler than the upper one, 
the apex obtuse or shortly and broadly acuminate, the base 
acute, the margins entire or very obscurely and distantly crenate ; 
lateral nerves 7 or 8 on each side of the midrib, curved-ascending, 
anastomosing, distinct; petioles jointed near the base, 5 to 8 
mm long. Inflorescence axillary, solitary, cymose, dichotomous, 
the peduncles a little longer than the petioles, the cymes about 
3 cm long and wide, rather many flowered. Flowers greenish- 
yellow, their pedicels about 4 mm long, subtended by very short, 
obscure bracteoles, apparently jointed to the inflorescence. Calyx 
about 3 mm in diameter, the lobes 5, rarely 4, orbicular-ovate, 
usually rounded, minutely ciliate on the margins. Petals 5, 
rarely 4, oblong, spreading, broadly rounded at the apex, about 
4 mm long, 2 mm wide. Stamens 3; filaments about 1.2 mm 
long ; anthers 0.5 mm in diameter. Ovary 3-celled ; cells 2-ovuled,
