9113, 9358 Rohmson are doubtfully referable to Heterospathe negrosensis; 
both were collected at about 900 meters’ altitude on Mount Binuang, In- 
fanta, Tayabas Province, Luzon. In regard to 9358 the collector notes that 
it is a plant 2 m high with the trunk 7 cm in diameter (this is probably 
the diameter of the upper part of the stem when covered with the mass 
of petiolar bases) and of the other that it is 4 m high.

on three nerves. Spadix twice branched. Fruit ovoid-ellipsoid, 
not or very slightly and asymmetrically obtuse-acuminate, 12 mm 
long, 7 mm thick. Seed ovoid, rounded at both ends; vascular 
branches of the integument very closely anastomosing.
