400 A FLORA OF MANILA 
* 1. P. VOLUBILIS Jacq. 
A climbing shrub reaching a length of 6 m or more, the younger 
parts and inflorescence pubescent. Leaves shortly petioled, ovate-elliptic 
to elliptic-oblong, scabrid, acute or acuminate, base narrowed, slightly 
cordate, 6 to 12 cm long. Racemes solitary, pendulous, up to 30 cm in 
length, the pedicels usually much longer than the pubescent calyx-tube. 
Flowers blue, the calyx-lobes narrowly-oblong, spreading, obtuse, about 
2 cm long, 5 mm wide, persistent. 
Somewhat cultivated, but not spontaneous, fi. Nov.Mar. A native of 
Central America and the West Indies, of comparatively recent introduction 
in the Philippines. 
‘ 7. SYMPHOREMA Roxburgh 
Climbing shrubs with opposite entire leaves. Flowers in peduncled 
6- to 9-flowered involucrate heads, the heads peduncled, in terminal 
panicles, the involucral bracts about 6, colored, enlarged and persistent 
in fruit. Calyx oblong-obovoid or narrowly funnel-shaped, 4- to 8-toothed. 
Corolla-tube a little longer than. the calyx, cylindric, usually 6-lobed. 
Stamens as many or twice as many as the corolla-lobes. Ovary 2-celled, 
4-ovuled; style filiform. Fruit nearly dry, included in the calyx, 1-seeded. 
(Greek “to bear together,” from the crowded involucrate flowers.) 
Species 3, 2 in India and 1 in the Philippines. 
1. S. luzonicum (Blanco) F.-Vill. 
A nearly glabrous woody vine 3 to 12 m in length. Leaves oblong to 
elliptic-oblong, 8 to 15 cm long, coriaceous, short-petioled, base usually 
rounded, apex acute or obtuse. Panicles somewhat pubescent, 8 to 30 cm 
long, the peduncles bearing the heads opposite, 2 to 6 cm long. Bracts 
pale-lavender or white, 2 to 4 cm long, spreading, oblong-elliptic, petioled. 
Calyx green, about 8 mm long, 6-toothed, pubescent outside, hirsute within. 
Corolla blue, 5- or 6-lobed, the lobes about 8 mm long. Stamens about 
twice as many as the corolla-lobes. 
In dry thickets Masambong to Fort McKinley, fl. Apr—May; widely dis- 
- tributed in the Philippines. Endemic. 
8. CALLICARPA Linnaeus 
Shrubs or small trees, the younger parts, the leaves, and the inflor- 
escence stellate-pubescent, often densely so. Leaves opposite, toothed, 
often waxy-glandular beneath. Cymes axillary, shorter than the leaves, 
the bracts small. Calyx small, cup-shaped or campanulate, slightly 4- 
toothed, not enlarged in fruit. Corolla purplish or lavender, tubular, 
nearly symmetrical, the lobes 4, spreading. Stamens 4, exserted. Ovary 
imperfectly 2-celled, cells 2-ovuled. Fruit a small, globose, usually pur- 
plish or lavender drupe. (Greek “beauty” and “fruit.”) 
Species about 40, mostly in south-eastern Asia, Malaya, and northern 
Australia, a few in Polynesia and tropical America, about 25 in the 
Philippines. 
Leaves densely stellate-pubescent beneath, the indumentum pale and quite 
covering the surface, the upper surface dark-colored when dry.
