ALABASTRA PHILIPPINENSIA, III. 
355 
A tree 8 m high, its trunk 10 cm in diameter, the branches with gray 
bark: leaves glabrous, palmately 4- or 5-foliolate; petioles 8.5 to 10 cm 
long, 1.5 mm wide in the middle, conspicuously swollen to 6 to 7 mm at 
the base, and more gradually and less constantly toward the apex ; petio- 
lules 18 to 35 mm long; lamina coriaceous, oval to oblong-obovate, 5.5 
to 9 cm long, 3 to 6 cm wide, the base acute, the margins ' revolute, the 
apex abruptly contracted into a blunt acumen 8 to 15 mm long; pairs of 
veins 6 to 8 with others nearly as prominent, loosely and often irregularly 
anastomosing. 
Luzon, Province of Tayabas (Infanta), Mount Binuang, in mossy forest at 
930 m elevation. Bur. Sci. 9435 Robinson. Closely allied in the nature of its 
inflorescence to S. brevipes Merr., but in S. binuangensis this is much shorter, 
the petioles much longer and not winged, and the leaflets fewer and smaller. 
ERICACEAE. 
DIPLYCOSI A Blume. 
Diplycosia opaca sp. nov. 
Arbuscula epiphytica, inflorescentiis exceptis glabra : inllorescentiis 
axillaribus, 1-ad 3-floris, pedicellis brevibus : foliis ellipticis, coriaceis, basi 
acutis, apiee retusis vel rarius truncatis, crasse apiculatis, margine inte- 
gris, revolutis; venis utrinque circa 3, obscuris. 
Flowers in the axils of present or fallen leaves, 1 to 3 at each node, 
fascicled, the pedicels 2 to 4 mm long, densely covered with nearly appres- 
sed pubescence: bracts at the base of the flowers paired, ovate obtusely 
acuminate, 2 mm long, pubescent near the margins and ciliate, together 
resembling a Cosmarium; calyx pinkish, urceolate, 3 mm long, divided 
two-thirds of the way to the base into 5 imbricate, ovate, subacute or 
obtuse ciliate lobes; corolla still undivided, 2 to 2.5 mm long; stamens 
10, 1 mm long, the filaments longer than the unappendaged anthers; 
ovary glabrous, less than 1 mm long, umbilicate, 5-celled, many-ovuled; 
style very short, the undivided stigma barely exerted from the umbilicus. 
An epiphytic shrub, about .1 m high, the vegetative parts entirely 
glabrous, the bark of the older stems cinnamon-brown, that of the young- 
er branchlets more often gray: leaves with petioles 5 to 9 mm long, the 
lamina coriaceous, elliptic, 4 to 8.5 cm long, 2 to 4 cm wide, the base 
acute, the margins entire, revolute, the apex retuse or merely truncate, 
shortly and stoutly apiculate, the under surface with scattered, minute, 
black, glandular dots ; all venation except the midrib very indistinct, but 
the lamina certainly triplinerved, with apparently two additional veins 
on each side of the midrib. 
Luzon, Province of Tayabas (Infanta), Mount Binuang, in mossy forest at 
an elevation of 900 m, Bur. Sci. 9385 Robinson. The leaf-apex seems entirely 
different from that of any other species of the genus, at once separating it 
from D. merrittii, its nearer Philippine ally.
