VERBENACEAE 403 



numerous, small but prominent glands. Panicles 25 cm long or less, ter- 

 minal and in the upper axils, the whole inflorescence bright-red. Flowers 

 odorless, slender, the corolla-tube about 1 cm long, the limb spreading, 

 somewhat oblique, subequally 5-lobed, 1.5 cm in diameter, the lobes oblong, 

 obtuse. Stamens deflexed or ultimately recurved, exserted about 2 cm, red 

 or purplish. Fruit depressed-globose, fleshy, blue, about 1 cm in diameter, 

 containing 3 or 4 seeds, the accrescent calyx red, spreading or reflexed, 

 about 2 cm in diameter. (Fl. Filip. pi. 173.) 



In open waste places, often in rather wet soil, fl. July-Nov. ; common and 

 widely distributed in the Philippines. Endemic, but with very closely 

 allied and perhaps identical forms in Formosa and Celebes. 



6. C. CALAMATOSUM L. 



An erect, shrubby or suffrutescent plant 1 to 2 m. high, sparingly pu- 

 bescent. Leaves elliptic to oblong-elliptic, 4 to 10 cm long, obtuse or 

 subacute, base acute, margins rather coarsely toothed. Flowers in few- 

 flowered cymes, in the upper axils, fragrant, white. Calyx 5 to 8 mm 

 long, 5-cleft. Corolla slender, pubescent, about 3 cm long. 



Occasionally cultivated for its fragrant flowers, fl. Oct.-Dec. A native 

 of Java, introduced in the Philippines, and at least subspontaneous in some 

 localities. 



7. C. cotnmersonll (Lam.) Spreng. (C. wertt/oHMm Wall.). 



An erect or somewhat scandent shrub 1 to 4 m high. Leaves ovate, 

 oblong-ovate, or elliptic-ovate, shining, glabrous, entire, obtuse, acute, or 

 slightly acuminate, 4 to 8 cm long, 2 to 3 cm wide. Peduncles axillary, 

 mostly 3-fiowered. Calyx green, narrowly funnel-shapied, truncate, with 

 5 very short teeth. Corolla about 3 cm long, the tube slender, white, the 

 lobes spreading, about 7 mm long, tinged with purple. Stamens long-ex- 

 serted, purple. Fruit obovoid, about 1.6 cm long, splitting into 4 pyrenes, 

 the calyx in fruit about 1 cm in diameter. (Fl. Filip. pi. 22U. C. inerme.) 



In thickets along tidal streams subject to the influence of salt water, fl. 

 at intervals all the year; throughout the Philippines in 'similar habitats, 

 .southern China to Malaya, Australia, and Polynesia. 



10. VITEX Linnaeus 



Shrubs or trees, rarely prostrate, glabrous or pubescent. Leaves op- 

 posite, digfitately 3-, or 5-foliolate, rarely simple. Inflorescence terminal 

 and axillary, composed of paniculately arranged cymes. Flowers blue or 

 jrellow. Calyx short, campanulate, truncate or shortly 5-toothed. Corolla- 

 tube cylindric, the limb 2-lipped, the central lobe of the lower lip much 

 larger than the others. Stamens 4,. in 2 pairs, exserted. Ovary 2- or 4- 

 celled, 4-ovuled. Fruit a small globose or obovoid drupe, the calyx some- 

 what enlarged, persistent. (A name used by Pliny for one species, or 

 some similar shrub.) 



Species about 60 in most tropical and warm countries, 10 or less in the 

 Philippines.
