ALABASTRA PHILIPPINENSIA, III. 
335 
Phyllanthus megalanthus sp. nov. § Eriococcus. 
Frutex glaber: floribus solitariis, pedicellatis, magnis; staminiferi 
perianthii segmentis integris 4, antheris 2, transverse dehiscentibus, 
glandulis liberis, approximatis ; pistilliferi perianthii segmentis 6, inte- 
gris, ovario stipitato, depresso-globoso, 6-sulcato, 3-loculare: foliis sub- 
oblongis, inaequilateralibus, basi obtnsis, apice acutis; stipnlis lineari- 
lanceolatis. 
Flowers solitary, more often near the apices of the branchlets : stami- 
nate flowers on pedicels 2 to 3 mm long; calyx-segments 4, 2.5 to 4 mm 
long, entire, varying in outline from narrowly lanceolate to orbicular- 
ovate, the inner usually the shorter and wider; disk-glands 4, free but 
closely approximate, granular; staminal column attainilig 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 m m 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 under surface much 
paler than the upper; stipules linear-lanceolate, 2 mm long, acute or 
sometimes forming an acute acumen for over half their length; venation 
pinnate, the thin veins about 6 pairs. 
Luzon, Province of Cagayan, Mount Alunleng-Bava, For. Bur. 112J/3 Curran, 
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. macrocalyx Muell.-Arg., of India, 
which differs in having larger, equilateral leaves, narrower stipules, and smaller 
staminate flowers with united glands. 
TRIGONOSTEMON Blume. 
Trigonostemon hirsutus sp. nov. § Eutrigonostemon. 
Arbuscula hirsuta: inflorescentiis axillaribus; floribus staminiferis in 
bractearum axillis fasciculatis, pistilliferis solitariis : foliis oblanceolatis, 
basi acutis, marginibus glandulosis ssepe denticulatis, apice breviter aeu- 
minatis, subtus hirsutis ; venis utrinque saepius 22.
