A scandant shrub, the branches and branchlets pale when 
dry, distinctly about 9-angled, sulcate, sparingly armed with 
widely scattered, short, straight, rather stout spines that do 
not exceed 2 mm in length. Leaves firmly chartaceous to sub- 
coriaceous, subolivaceous when dry, prominently shining on 
both surfaces, oblong-ovate to oblong-elliptic, 8 to 16 cm long, 
3.5 to 10 cm wide, all with a stout apiculate-acuminate apex, 
the smaller ones rounded at the base, the larger ones prominently 
cordate, 5- or 7-nerved, the inner pair of nerves much stouter 
than the outer ones, reaching the apex, the reticulations rather 
lax, prominent; petioles 1 to 2 cm long, the lower part somewhat 
sheathing, the tendrils attaining a length of about 10 cm. Um- 
bels axillary, solitary, their peduncles 2.5 to 3 cm long, the 
pedicels in fruit 1.5 to 2 cm long. Fruits globose, numerous, 
nearly black when dry, somewhat wrinkled, prominently shining,

Luzon, Tayabas Province, vicinity of Dingalan, on the Pacific coast,

altitudes. 
A species well characterized by its inflorescences being reduced to a 
simple umbel. In vegetative characters it somewhat resembles SMILAX 
ELMERI nom. nov. ( Smilax reticulata Elm. Leafl. Philip. Bot. 8 (1815) 
2740, non Desv., nec Heer), but Smilax elmeri has raeemosely arranged 
umbels, and its leaves are acute at the base.
