female flowers form a shallow truncate cup, 3 mm wide. Fruit 
narrowly ovoid, 10 to 12 mm long, 5 mm broad, slightly asym- 
metrical, being faintly obliquely conical in its upper part, the 
apex marked by a minute mammillaeform areola, bearing the 
remains of the stigmas; the surface is dull and even (not 
roughened by underlying sclerosomes) , the epicarp thinly crus- 
taceous, the mesocarp with 3 or 4 layers of strongly flattened, yet 
soft, fibers, the endocarp very thin, pellicular. Seed ovoid-ellip- 
soid, rather acute, 7 mm long, 4 mm thick; hilum sharply im- 
pressed all along one side ; testa brown and polished ; the vascular 
branches of the integument form a loose network all around the 
seed ; albumen radiately ruminate ; embryo basal.

This species is closely related to Ptychoraphis intermedia, but 
is distinguishable by its smaller fruits, considerably narrowing 
in their upper part, and by the ellipsoid, acute seeds having 
the vascular branches loosely anastomosing.

this specimen agreeing very well with that from Mindanao. 
This species is closely related to Ptychoraphis microcarpa, from 
which it differs in its larger spadix having longer and thicker 
fructiferous branches and in the leaflets having paleolae not only 
on the midcosta but also on three nerves underneath, but more 
especially in the shape and size of the fruit and in the seed, 
which is rounded at both ends and marked by the close network 
of the vascular branches of the integument. Both Ptychoraphis 
microcarpa and Pt. intermedia are more closely related to Pt. 
angusta, of the Nicobar Islands, than to Pt. singaporensis, of 
the Malay Peninsula and Singapore.
