a rusty furfuraceous band. The spadix has more or less per- 
manently rusty-furfuraceous, 10 to 20 cm long or less, floriferous 
branches, bearing on their lower parts a few female flowers, 
each of which is accompanied, as usual, on each side, by a male 
flower; the upper parts of the branches present male flowers 
only. The male flowers are very narrow, 1 cm long and 2 to 
3 mm broad, sinuous, acuminate; calyx very shortly campanu- 
late, sharply 3-toothed; petals about five times longer than the 
calyx, narrowly lanceolate, with the tips acuminate and more 
or less faleate; stamens 6, slightly shorter than the petals; fila- 
ments short; anthers linear, sinuous, emarginate at the apex. 
Female flowers pyramidal-trigonous, acuminate, 6 to 8 mm 
long; calyx relatively large, shallowly cupular, with three, broad, 
acuminate teeth, but latter splitting into three broad lobes; 
corolla about two and one-half times as long as the calyx; 
petals elongate-triangular, acuminate, 6 to 7 mm long, 3 mm 
broad at their bases; staminodia 6, subulate, not bearing rudi- 
mentary anthers. Fruiting perianth measuring about 9 mm be- 
tween the tips of the petals. Fruit globose, slightly diminishing 
toward the base, or subpyriform, 4 to 4.5 cm long, 3 to 3.8 cm 
broad; mesocarp relatively thin, 1.5 to 2 mm thick; kernel, when 
detached from the mesocarp, with a blunt, not clearly defined 
prominence at the base; walls of the endocarp 0.33 mm thick 
at the sides. Seed globular with a flattish base, the vascular 
branches of the integument few, ascending, sinuous, not or 
very slightly divided. Embryo very slightly and excentrically 
apical.

This is easily distinguishable from Orania philippinensis by 
the general rusty coating which covers the leaf-rachis and the 
axial parts of the spadix; by its long and narrow male flowers, 
three to four times longer than broad; by the trigonous, acu- 
minate female flowers having a campanulate calyx, and the. 
petals elongate-triangular, twice as long as broad, at least; and 
by the subpyriform fruit, considerably smaller than that of 
O. philippinensis, and with a thin mesocarp. 
Apparently also referable to O. rubiginosa is Loher 7090 
collected at Angilog, Rizal Province, Luzon (Herb. Kew.), of 
which the collector notes that it is a tree 3 to 4 m high with a 
thick stem. In this specimen the leaflets are larger than in the 
type, and the fruits also are somewhat larger, 5 cm long and 4 
cm thick, and have the mesocarp 2.5 mm thick.
