10. COFFEA Linnaeus 
Shrubs or trees with opposite leaves and broad stipules. Flowers white, 
axillary, solitary, or in fascicles or cymes. Calyx-tube short, the limb 
often persistent. Corolla-tube long or short, the lobes 4 to 7, spreading. 
Anthers as many as the corolla-lobes, sessile. Ovary 2-celled; style slen- 
der; ovules 1 in each cell. Fruit fleshy, with 2 plano-convex, coriaceous or 
cartilaginous, 1-seeded pyrenes, the seeds concave or grooved ventrally. 
_(Latinization of the common name, said to be derived from the name 
of a locality in Africa.) 
Species 40, in the tropics of the Old World, 2 introduced in the Phil- 
ippines. 
*1. C. ARABICA L. Café (Sp.); Coffee. 
A small tree reaching a height of 4 or 5 m, quite glabrous. Leaves 
elliptic-ovate to elliptic-oblong, acuminate, base acute, shining, 8 to 15 
em long. Flowers white, in axillary fascicles, the corolla about 1.5 em long. 
Fruit red, ovoid or ellipsoid, about 1.4 cm long. (Fl. Filip. pl. 53.) 
Occasionally cultivated in our area, fl. most of the year; more or less 
cultivated in all parts of the Philippines. A native of south-western Asia, 
now cultivated in most tropical countries. 
11. IXORA Linnaeus 
Shrubs or small trees, glabrous or nearly so, with opposite leaves, 
Flowers 4-merous, white, pink, or red, few to many in terminal, trichotom- 
ously branched cymes, usually 2-bracteolate. Calyx-tube ovoid, 4-toothed. 
Corolla-tube slender, cylindric, elongated, the lobes spreading, twisted in 
bud. Stamens 4, alternate with the corolla-lobes. Ovary 2-celled; style 
filiform, slightly exserted; ovules 1 in each cell. Fruit globose, somewhat 
fleshy, with 2, 1-seeded, plano-convex, coriaceous pyrenes. (A name used 
by Rheede, after Baldaeus, the flowers of one species being offered to 
“the god Ixora” (?Isvara) in Ceylon.) 
Species 125 or more, chiefly in tropical Africa and Asia, about 20 in 
the Philippines.
