1. ROSMARINUS Linnaeus 
An erect, much-branched, aromatic undershrub. Leaves sessile, linear. 
Flowers small, in short, axillary and terminal racemes. Calyx 2-lipped, 
the upper lip entire, the lower one bifid. Corolla exserted, the throat 
somewhat inflated, the upper lip erect, emarginate, the lower one spread- 
ing, trifid, the middle lobe large, concave. Stamens 2, ascending, exserted, 
under the upper lip. (Latin “dew” and “sea.’’) 
A monotypic European genus. 
*1. R. OFFICINALIS L. Romero (Sp.); Rosemary. 
An erect undershrub 1 m high or less, the branches and leaves densely 
arranged. Leaves linear, sessile, entire, the margins strongly revolute, 
the lower surface gray-pubescent, 1 to 3 cm long. Racemes 1 to 3 cm 
long, the bracts shorter than the calyx. Flowers less than 1 cm long, 
blueish. (FI. Filip. pl. 94.) 
Quite extensively cultivated in Paranaque, the living plants sold in 
Manila; in cultivation many towns in the Philippines. Introduced from 
Spain at an early date, but not spontaneous here. 
2. OCIMUM Linnaeus 
Erect, branched, aromatic herbs or small shrubs. Leaves ovate, entire 
or toothed. Inflorescence of solitary or panicled, interrupted racemes, the 
flowers arranged in whorls, the pedicels short, spreading or recurved, 
Flowers small, Calyx deflexed in fruit, the upper lobe broad, the margins 
decurrent, the lower 2 acuminate, the lateral ones shorter than the lower 
ones. Corolla slender, more or less exserted, 2-lobed, the upper lip broader, 
subequally 4-fid, the lower entire. Stamens exserted, declinate. Nutlets 
smooth or somewhat rugose. (From an old Greek name.) 
Species about 40, chiefly in tropical Asia, 2 or more in the Philippines. 
Fruiting calyx strongly reflexed, the upper lobe orbicular; pedicels shorter

1. O. BASILICUM L. Solasi (Tag.); Bonac, Caloy (Vis.). 
An erect, branched undershrub 0.5 to 1.5 m high, glabrous or somewhat 
pubescent, very aromatic. Leaves ovate to oblong-ovate, entire or slightly 
toothed, acute, 1.5 to 3 cm long. Racemes 8 to 15 cm long, usually pur- 
plish, the pedicels short. Calyx strongly reflexed in fruit, the upper lobe 
orbicular, the lower two narrow lanceolate, acuminate, the lateral ones 
ovate. Corolla exserted, pink or purplish, 9 to 10 mm long. 
Occasionally cultivated, fl. all the year; generally cultivated in the 
Philippines, but certainly not a native species. Tropical Asia and Africa 
through Malaya to Polynesia, in many places, however, only in cultivation.
