 4. Calyx-teeth 6 to 10, the tube ribbed, the mouth often oblique; 

 upper lip of the corolla densely woolly outside; flowers white; 



low herbs 9, £,g„eas

1. ROSMARINUS Linnaeus 



An erect, much-branched, aromatic undershrub. Leaves sessile, linear. 

 FJowers 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. (Fl. Filip. pi. U.) 



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. OCrMUM 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-fld, the lower entire. Stamens exported, 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 

 than the calyx 1. O. basilicum 



Fruiting calyx spreading or slightly reflexed, the upper lobe oblong-ovate; 

 pedicels much longer than the calyx i. O. sanctum 



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 «xserted, 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.
