1. UVARIA Linnaeus 
Scandent shrubs usually more or less stellate-pubescent. Flowers ter- 
minal, leaf-opposed, or extra-axillary, cymosely fascicled or solitary. Sepals 
3, densely pubescent. Petals 6, orbicular, imbricate in 2 rows, spreading. 
Stamens indefinite; top of the connectives truncate. Ovaries many, linear- 
oblong; ovules many, 2-seriate, rarely few or 1-seriate. Ripe carpels 
fleshy, usually many-seeded. (Latin “grape,” from the resemblance of the 
fruit of some species.) 
A large genus, chiefly of tropical Asia and Malaya, about 12 known to 
occur in the Philippines, a single one in our area. 
1. U. rufa Blume. Susong-calabao (Tag.). 
A seandent shrub often 5 to 6 m in length, the younger parts and lower 
surfaces of the leaves rather densely and softly pubescent with stellately 
arranged, rusty, short hairs. Leaves oblong-ovate to oblong-lanceolate, 8 
to 16 cm long, apex acuminate, base rounded or cordate, the petioles very 
short. Flowers extra-axillary, solitary or 2 or 3 in depauperate cymes, 
usually about 1.5 to 2 cm in diameter. Fruits fleshy, red when mature. 
(Fl. Filip. pl. 195, U. purpurea.) 
In thickets, La Loma to Guadalupe, fl. May-July; rather widely dis- 
tributed in the Philippines at low altitudes; Malay Archipelago. 
2. ARTABOTRYS R. Brown 
Scandent shrubs with shining leaves. Flowers mostly solitary, usually 
on woody, mostly hooked, recurved peduncles. Sepals 3, valvate. Petals 
6 in 2 series, their bases concave, connivent, the limbs spreading, flat or 
terete. Stamens many, oblong or cuneate, the connectives truncate or 
produced. Torus flat or convex. Ovaries few or many; style oblong; 
ovules 2, erect. Ripe carpels fleshy. (Greek “joint” and “panicle,” in allu- 
sion to the peculiar inflorescence.) ‘ 
Species about 25, tropical Africa, Asia, and Malaya, about 4 in the 
Philippines, a single introduced one in our area.
