6. PSEUDERANTHEMUM Radlkofer 
Erect herbs or undershrubs, the leaves entire or coarsely toothed. In- 
florescence spicate, racemose, or cymose, axillary or terminal, few-flowered, 
the flowers 1 to 3 in the axils of small, linear bracts. Calyx lobes 5, narrow. 
Corolla-tube long, slender, cylindric, the limb somewhat 1-lipped, lobes 5, 
spreading, subequal, or the 2 posterior ones somewhat smaller than the 
others. Stamens 2, inserted on the tube; staminodes 2. Ovules 2 in each 
cell. Capsule long-stalked. Seeds 4 or less. (Greek “false” and Eran- 
themum, an allied genus.) 
Species about 60 in all tropical countries, 1 or 2 in the Philippines. 
1. P. pulchellum (Hort.) Merr. (P. bicolor Radlk.; Eranthemum bicolor 
Schrank). Cinco llagas (Sp.-Fil.). 
An erect, branched, rather slender undershrub or suffrutescent plant 
usually about 1 m high, nearly glabrous or somewhat pubescent. Leaves 
thin, elliptic-ovate to oblong-ovate or oblong-lanceolate, 5 to 12 cm long, 
the upper ones often much reduced, acute or acuminate, base decurrent. 
Peduncles axillary, longer than the petioles, bearing near their apices 1 
to 3 or more racemose or cymose flowers. Calyx green, 5. to 7 mm long, 
the teeth elongated linear. Corolla white, middle lobe of the lower lip 
with a large purple spot at the base, the tube slender, 2.5 to 3 cm long, 
the lobes spreading, elliptic to elliptic-oblong, about 1.2 cm long. Capsule 
pubescent, 2 cm long, stalked. (FI. Filip. pl. 9, Justicia gendarussa.) 
In dry thickets, Masambong, near Fort McKinley, etc., fil. Oct.—Apr.; 
widely distributed in the Philippines. Malaya. 
7. RHINACANTHUS Nees 
Erect branched shrubs with entire leaves. Inflorescence terminal, of 
divaricate panicled cymes, few-flowered. Flowers solitary or in groups of 
2 or 8, sessile, the bracts and bracteoles linear-lanceolate, small. Calyx 
small, 5-lobed or -partite, the segments linear-lanceolate. Corolla white, 
the tube long, slender, the limb spreading, 2-lipped, the upper lip small, 
lanceolate, entire or 2-toothed, curved or twisted, the lower broad, 3-lobed. 
Stamens 2, inserted near the top of the corolla-tube. Capsule clavate, 
4-seeded, long-stalked. (Greek “nose” and Acanthus, another genus of 
this family.) 
Species 4, tropical Asia and Africa, a single one in the Philippines.

1. R. NAsuTA (L.) Kurz. (R. communis Nees). Cinco llagas na puti, Sili-

A slender, erect, branched, somewhat pubescent shrub 1 to 2 m high. 
Leaves oblong, narrowed at both ends, obtuse or acute, 4 to 10 cm long. 
Inflorescence a spreading, leafy, pubescent. panicle, the flowers usually 
clustered. Calyx green, pubescent, 5 mm long. Corolla-tube slender, cylin- 
dric, greenish, 2 cm long, the upper lip white, erect, oblong or lanceolate, 2- 
toothed at the apex, about 8 mm wide, long, the lower lip broadly obovate, 
11 to 13 mm long, and wide, 3-lobed, white, with few minute brownish dots 
near the base. (FI. Filip. pl. 10.)

plant in the Philippines, although now widely distributed in and about towns. 
India to Madagascar and Malaya, but frequently only cultivated.
