314 A FLORA OF MANILA 
rounded, the other acute; stipules slender, hairy, short, deciduous. Flowers 
2 cm in diameter, white, extra-axillary, solitary or in pairs, their pedicels 
erect, 1.5 to 2.5 em long. Sepals 5, green, reflexed, lanceolate, long-acumi- 
nate, 1 cm long. Petals obovate, deciduous, 1 cm long, spreading. Stamens 
many. Fruit a globose, red, smooth, very fleshy, sweet berry, about 1.5 
cm in diameter, filled with very numerous, small seeds. (FI. Filip. pl. 425.) 
Common in and about Manila, fi. all the year. A native of tropical 
America, introduced here and naturalized; also introduced in Siam. The 
very sweet fruits are much eaten by children. ’ 
4. TRIUMFETTA Linnaeus 
Erect or prostrate branched herbs or undershrubs, more or less stellate- 
pubescent. Leaves toothed, simple or lobed. Flowers yellow, in dense 
axillary cymes or fascicles. Sepals and petals 5, free. Stamens 5 to 35, 
springing from a lobed torus. Ovary 2- to 5-celled, cells 2-ovuled. Cap- 
sule globose, covered with short or long, often hooked spines, dehiscent or 
indehiscent. (In honor of G. B. Trionfetti, and Italian botanist.) 
A genus of about 40 species of wide tropical distribution, about 6 in the 
Philippines, two in our area. 
Inflorescence rather dense; spines of the fruits glabrous .... 1. T. bartramia 
Inflorescence rather lax; spines of the fruits with reflexed hairs. 
2. T. semitriloba 
1. T. BARTRAMIA L. (T. rhomboidea Jacq.). Calot-calotan (Tag.). 
An erect, more or less hairy, branched, annual, often suffrutescent herb, 
0.5 to 1.5 m high. Leaves variable, usually orbicular or rhomboid-ovate, 
base rounded, apex 3-lobed, denticulate, the upper ones much reduced, oblong 
to ovate-lanceolate, not lobed. - Flowers yellow, about 6 mm long, numerous, - 
in rather dense axillary fascicles. Fruit small, globose, pubescent, covered 
with hooked spines, the spines glabrous. 
In waste lands, fl. Oct.-Feb.; widely distributed in the Philippines, but 
undoubtedly introduced here. Tropical Asia, Africa, and Malaya. 
2. T. SEMITRILOBA Jacq. Calot-calotan (Tag.). 
An erect, branched, suffrutescent or shrubby plant, 1 to 2 m high, more 
or less stellate-pubescent. Leaves 3 to 10 cm long, broadly ovate to ovate, 
or the upper ones oblong, base usually broad, rounded, or of the upper ones 
acute, subentire, or slightly 3-lobed in the upper part, margins toothed. 
Flowers yellow, in rather lax axillary clusters, the buds oblong, up to 9 
mm long. Sepals apiculate. Fruits globose, 7 to 8 mm in diameter, pu- 
bescent, covered with hooked spines, the spines with scattered, reflexed 
hairs. 
In open dry lands, thickets, etc., fi. Dec.Feb.; widely distributed in the 
Philippines, but undoubtedly introduced here. Tropics generally. 
5. CORCHORUS Linnaeus 
Erect or spreading, branched, often suffrutescent herbs, nearly glabrous 
or more or less stellate-pubescent. Leaves simple, with usually 2 short, 
tail-like appendages at the base. Flowers small, yellow, axillary. Sepals 
and petals 4 or 5. Stamens usually many, springing from a short torus. 
Ovary 2- to 6-celled. Capsule elongated or subglobose, loculicidally 2- to 
5-valved. (An old Greek name for some bitter plant.)
