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 scandent 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. pi. 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, usuallir 

 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.

 Leaves oblong-elliptic to oblong-lanceolate, acuminate, base acute, 9 to 16
