perianthii segmentis integris 4^ antheris 2, transverse dehiscentibus, 
glandulis liberis, approximatis ; pistilliferi perianthii segmentis 6, inte- 
gris^ ovario stipitato, depresso-globoso, G-sulcato, 3-locuIare: foliis sub- 
oblongis^ inaequilateralibns, basi obtusis, apice aciitis; stipulis lincari- 
lanceolatis. 
Flowers solitar}^, more often near the apices oi; the branchlets : stami- 
nate flowers on pedicels 2 to 3 mm long; calyx-segments 4., 2.5 to 4 mm 
long, entire, varjdng in outline from narrowly lanceolate to orbicular- 
ovate, the inner usually the shorter and wider; disk-glands 4, free but 
closely approximate, gi'anular; staminal column attaining a length of 
2 mm and a diameter of 1 mm, the 4 anther-cells forming a ring at 
its apex and dehiscing transversely, inclosing a rudimentary ovary 0.3 
to 0.5 mm long and 0.8 to 1.2 mm wide: pistillate flowers on pedicels 
8 to 10 mm long; calyx-segments 6, entire, the outer oval, about 6 mm 
long, the inner obovate, about 7 mm long; disk-glands forming a more 
or less undulate ring, granular; ovary shortly stipitate, depressed-globose, 
glabrous, 1 mm long, 6-grooved, 3-celled; stylar column entire for about 
1.2 mm, then 3-lobed for a slightly longer distance, the lobes bifid for 
about half their length and recurved: fruiting calyx enlarged, seen up 
to 13 mm long; stipe 1 mm long; capsule 3 mm long, 4 mm in diameter. 
A shrub, 1 m high, glabrous throughout, the branches roughened by 
the scars of fallen branchlets, covered with reddish bark, the branchlets 
tending to become crowded at the apex; about 20 pairs of leaves on each 
branchlet: petioles about 1 mm long; lamina membranaceous, nearly 
oblong, usually about 20 mm long and 7 mm wide, attaining 24 mm by 
10 mm, usually inequilateral throughout its length, the base rounded on 
both sides or acute on the lower, the apex acute, the undei- surface much 
paler than the upper; stipules linear lanceolate, 2 mm long, acute or 
sometimes fonning an acute acumen for over half their length; venation 
pinnate, the thin veins about 6 pairs. 
Luzon, Province of Cagavan, Mount Alunleng-Bava, For. Bur. 17243 Gunan, 
growing on exposed ridges at an elevation of 200 m. Among Philippine species, 
this comes nearest to P. stipularis Merr., from which it is at once distinguished 
by the size of the calyx. Its closest ally is P, maorocalyx Muell.-Arg., of India, 
which differs in having larger, equilateral leaves, narrower stipules, and smaller 
Btaminat« flowers with united glands.
