 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. (Greel( "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 Recurrent. 

 Peduncles axillary, longer than the petioles, bearing near their apices 1 

 to S 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. (Fl. Filip. pi. 9, Justicia gendarussa.) 



In dry thickets, Masambong, near Fort McKinley, etc., fl. Oct.-Apr.; 

 widely distributed in the Philippines. Malaya. 



7. RHINACANTHU$ Nees 



Erect branched shrubs with entire leaves. Inflorescence terminal, of 

 divaricate panicled cymes, few-flowered. Flowers solitary or in groups of 

 2 or 3, 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. (fi. communis Nees) . Cinco llagas na puti, Sili-

A slender, erect, branched, somewhat pubescent shrub 1 to 2 m high.

 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 3 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. (Fl. Filip. pi. lo.) 



Common in thickets and hedges, fl. Dec-March; certainly an introduced 

 plant in the Philippines, although now widely distributed in and about towns. 

 India to Madagascar and Malaya, but frequently only cultivated.
