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. 



Samar, Catubig River at Tagabiran, Bur. Sci. 2H25 Ramos, February 

 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.

A tree 6 to 8 m high, glabrous except the more or less pubescent 

 younger parts and the very sparingly pubescent inflorescence. 

 Branches stout, the ultimate ones 1 to 1.5 cm in diameter, the 

 petiolar scars large, prominent. Leaves ovate, chartaceous to 

 subcoriaceous, 50 to 65 cm long, 25 to 35 cm wide, rather pale- 

 olivaceous when dry, slightly shining, base somewhat narrowed, 

 slightly cordate, apex abruptly short-acuminate, the lower sur- 

 face often densely and minutely white-puncticulate on the nerves 

 and reticulations, in age quite glabrous ; lateral nerves about 14 

 on each side of the midrib, prominent, somewhat curved, anas- 

 tomosing very close to the margin; petioles 9 to 15 cm long. 

 Staminate panicles axillary, numerous, rather narrow, up to 20
