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 apieulate-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

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

 Bur. Sci. 26611 Ramos & Edano, August 27, 1916, on dry slopes at medium 

 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. Lean. Philip. Bot. 8 (1815) 

 2740, non Desv., nee Heer), but Smilax elmeri has racemosely arranged 

 umbels, and its leaves are acute- at the base.
