and branchlets terete, the former pale, the latter smooth, 
reddish-brown, slender, about 1 mm in diameter, the internodes 
2.5 to 6 cm long. Leaves quarternate, chartaceous to subcoria- 
ceous, lanceolate, 4 to 7 cm long, 1 to 2 cm wide, narrowed below 
to the acute base and above to the slenderly but obtusely acumi- 
nate apex, the upper surface subolivaceous when dry, shining, 
the lower much paler, the midrib prominent but the lateral 
nerves obsolete or subobsolete; petioles 2.5 to 5 mm long. In- 
florescences axillary, solitary, peduncled, umbellate, about 2 cm 
long, each with 3 to 5 pedicelled flowers at the apex of the 
peduncle, the pedicels 2 to 3 mm long, the bracteoles oblong- 
ovate, subacute, 1 mm long. Calyx-tube very short, the lobes 
ovate-lanceolate, acuminate, 2 mm long. Corolla-tube cylindric, 
6 to 7 mm long, the lobes oblong-ovate, somewhat acuminate, 3 
mm long. 
Luzon, Tayabas Province, Infanta-Siniloan trail, Bur. Sci. 29209 Ramos 
& Edano, June 14, 1917, in damp forests. Bur. Sci. 28627 Ramos & Edaiio 
from Mount Binuang, May, 1917, probably represents the same species, 
but the flowers are very young and the leaves are uniformly dark-brown 
on both surfaces; the difference in color in the dried specimens is probably 
due to a difference of method in drying them. 
The species is a very characteristic one and is distinguished by its 
lanceolate, prominently acuminate, practically nerveless leaves and its 
simple umbellate inflorescences.

A scandent glabrous shrub, the stems terete, 3 to 4 mm in 
diameter, the branchlets dark-brown, smooth, very slender, 1 
to 2 mm in diameter, the older ones terete, the younger ones
