basi distincte decurrentibus ; spadicis cylindraceis, sessilibus, 
circiter 7 cm longis et 8 mm diametro. 
Scandent, glabrous, all parts pale when dry. Branches 3 to 
5 mm in diameter, the internodes 3 to 7 cm long. Leaves oblong 
to oblong-lanceolate, chartaceous, 15 to 25 cm long, 4 to 6 cm 
wide, the uppermost ones sometimes smaller, slightly inequilat- 
eral, one side about one-third narrower than the other, base 
acute, apex slenderly caudate-acuminate, the caudiform part up 
to 1 cm in length; collective nerves two on each side of the 
midrib, from or near the base ; lateral nerves numerous, slender, 
about as prominent as the collective ones, up to 40 on each side 
of the midrib ; petioles 5 to 8 cm long, narrowly winged. Pedun- 
cles axillary, solitary, about 10 cm long, slightly thickened up- 
ward. Spathes oblong, about 6 cm long and 1.2 cm wide, apex 
slenderly caudate-acuminate, the base distinctly decurrent. 
Spadices cylindric, about 6 cm long, sessile, obtuse, about 8 mm 
in diameter, densely many flowered.

10, 1916, climbing on trees in damp forests at low altitudes. 
The alliance of this species is with Pothos rumphii Schott and P. in- 
signis Engl., from both of which it differs in many characters. It is most 
closely allied to the latter.

and reticulations, in age quite glabrous; lateral nerves about 14 
on each side of the midrib, prominent, somewhat curved, anas-
