9443, 9358 Robinson 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 4m high.

Conspectus of the species. 
a’. Fruit longer than broad. . 
b*. Of medium size. Leaflets furnished underneath with a few paleolae 
on the midrib only. Spadix twice branched. Fruit narrowly ovoid, 
tapering above to a slightly oblique, conical point, 10 to 12 mm 
long, 5 mm thick. Seed ovoid-ellipsoid, subacute, 7 mm long, 4 
mm thick; vascular branches of the integument loosely anastomosing. 
1. Pt. microcarpa. 
6’. Of medium size. Leaflets furnished underneath with paleolae, often 
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. 
2. Pt. intermedia. 
b*. Robust, stem about 15 m high. Spadix thrice branched. Leaflets 
rigid, without paleolae on the lower surface ; secondary nerves 
well marked; margins somewhat thickened. Fruit narrowly ovoid, 
tapering above to a conical, slightly oblique point, 12 to 13 mm 
long, 5 mm broad. Seed ovoid-ellipsoid, acute, 9 mm long, 4.5 mm 
thick; vascular branches of the integument loosely anastomosing. 
8. Pt. Elmerii. 
a’. Fruit spherical. Stem about 6 m high. Leaflets long-acuminate, the 
point slightly faleate. Spadix thrice branched, floriferous branches 
12 to 15 cm long, 2.5 to 8 mm thick. The bracteoles of the female 
flower form a regular cupular caliculum. Fruiting perianth shallowly
