8. GRAPTOPHYLLUM Nees \ 
Erect glabrous shrubs with purple or variegated leaves. Inflorescence 
terminal, paniculate, the flowers pedicelled, arranged in few-flowered clus-— 
ters, the bracts and bracteoles small. Calyx small, 5-parted, the lobes equal, 
linear-lanceolate. Corolla elongated, the tube inflated upward, the limb very 
oblique, 2-lipped, the upper lip shortly 2-fid, the lower one 3-lobed. Stamens 
2; staminodes 2, small. Ovary 4-ovuled. Capsule oblong, hard, long-stalked, 
(From the Greek “writing” and “leaves,” in allusion to the variously marked

*1. G. pictuM (L.) Griff. (G. hortense Nees). Morado (Sp.-Fil.) ; Sarasa, 
Balasbas (Tag.). 
An erect branched shrub 2 to 3.5 m high, glabrous throughout. Leaves 
opposite, entire, oblong to broadly elliptic, narrowed at both ends, somewhat 
acuminate, shortly petioled, 10 to 20 cm long, dull-purple, or green and va- 
riously mottled with white or gray. Inflorescence 6 to 12 cm long. Corolla 
dull-purple or reddish-purple, about 4 cm long. (FI. Filip. pl. 7, 8.) 
Commonly cultivated for its ornamental foliage, and in hedgerows etc., 
fil. most of the year; in and about towns troughout the Philippines, but not 
spontaneous. Probably a native of Polynesia, now cultivated in most trop-

large, coherent by their margins at least when young. Calyx small, anular, 
10- to 16-toothed, often obscure. Corolla large, the tube ventricose, curved, 
the lobes 5, rounded. Stamens 4, in 2 pairs, near the base of the corolla- 
tube. Disk cushion-shaped or annular. Style long. Capsules globose,
