1. G. spinosa (Blanco) Merr. & Rolfe. 
A somewhat scandent, glabrous shrub 1 to 4 m high, the axils usually 
with very small; short spines. Leaves obovate to oblong-obovate, apex 
rounded, base wedge-shaped, margins finely toothed, 5 to 10 cm long. 
Cymes small, axillary, rather few-flowered, slender, subumbellate, 1 to 2 
em long. Flowers small, greenish-white, 5-merous, the calyx-teeth small. 
Petals oblong, obtuse, 3 mm long. Capsules red, subglobose, 5 to 8 mm 
long, somewhat 3-angled. 
In thickets, Masambong to Pasay, fl. Oct.-Dec.; widely distributed in 
the Philippines. . Endemic. 
3. SIPHONODON Griffith 
Small glabrous trees with alernate, shortly petioled, slightly crenate 
leaves. Inflorescence axillary, subcymose, few-flowered. Flowers small, 
5-merous, Calyx 5-cleft. Petals 5, spreading. Disk not distinct.  Sta- 
mens 5, connivent around the pistil, the filaments flattened. Ovary half- 
immersed, conical, the summit hollowed out, stigmatose in the cavity; cells 
numerous in 2 to 4 series, each 1l-ovuled. Fruit ovoid or globose, hard, 
of uniform texture throughout, the pulp brittle when dry, the numerous 
seeds scattered irregularly through the dry pulp. 
Species 3, India to Australia, 2 in the Philippines. 
1. S. celastrineus Griff. Matang-olang (Tag.). 
A small tree 5 to 8 m high. Leaves pale when dry, oblong, shining, 
coriaceous, 12 to 22 cm long, acuminate, base acute, the petiole less than 
1 cm long. Flowers small, greenish, the petals about 1.5 mm long. Fruit 
globose or ovoid, pale when dry, glabrous, 1.5 to 2.5 cm in diameter. 
In dry thickets Masambong, San Francisco del Monte, etc., fl. May; 
of wide distribution in the Philippines at low altitudes, India to Malaya. 
76. HIPPOCRATEACEAE (HIPPOCRATEA FAMILY) 
Scandent, unarmed, usually glabrous shrubs with opposite, rarely alter- 
nate, simple, entire or slightly toothed leaves. Flowers small, regular, 
perfect, in axillary or terminal fascicles or cymes. Calyx-tube short, the 
lobes 5, imbricate. Petals 5, free, inserted under the disk, imbricate, rarely 
valvate. Disk strongly developed, usually thick and fleshy, lobed or entire. 
Stamens 3, rarely 2, 4, or 5, inserted on the disk; filaments short, flattened, 
free, or somewhat adnate to the ovary, recurved. Ovary surrounded by 
the disk, 3-celled; ovules 2 to 10 in each cell. Fruit subglobose, baccate or 
drupaceous, 1- to 8-celled, fleshy, indehiscent, or of 3 elongated flattened 
carpels which are connate below, and usually dehiscent. Seeds winged or 
not. 
Genera 2, species about 150 in the tropics of both hemispheres, 2 genera 
and 5 or 6 species in the Philippines.
