2. LANTANA Linnaeus 



Erect or subscandent aromatic shrubs, usually prickly, pubescent or 

 scabrous. Leaves simple, crenate. Inflorescence axillary, the flowers in 

 peduncled, ovoid to oblong, short heads or spike-like heads. Calyx small, 

 thin, truncate or slightly toothed. Corolla-tube slender, cylindric, the lobes 

 4 or 5, spreading. Stamens 4, in 2 pairs, included. Ovary 2-celled, 2- 

 ovuled. Fruit fleshy, containing 2, hard, 1-celled pyrenes. (An ancient 

 name for one of the viburnums.) 



Species about 40, chiefly in tropical America, a single introduced one in 

 the Philippines. 



1, L. CAMABA L. 



An erect or subscandent, somewhat hairy, aromatic shrub, when erect 

 usually 1 to 2 m high, when scandent twice as high. Leaves ovate, acu- 

 minate, toothed, 6 to 9 cm long. Flowers in peduncled many-flowered heads 

 including the corollas 2 to 3.6 cm in diameter. Corollas pink, red, or 

 yellow, about 1 cm long, the limb 6 to 7 mm wide. Fruits in an ovoid, 

 2 cm long head, on a thickened, fleshy receptacle, the individual ones ovoid, 

 purple or black, fleshy, about 5 mm long. (Fl. Filip. pi. Z16.) 



In waste places, thickets, etc., abundant, fl. all the year; widely distrib- 

 uted and thoroughly naturalized in the Philippines. A native of. tropical 

 America, now found in most tropical countries. 



3. LtPPIA Linnaeus 



Prostrate herbaceous plants (in our species) with opposite toothed leaves. 

 Flowers' small, in peduncled, solitary, axillary, dense, ovoid or cylindric 

 spikes, each subtended by a broad, ovate or obovate bract. Calyx small, 

 2-fid. Corolla-tube slender, the limb 2-Iipped, spreading. Stamens 4, in 2 

 pairs, included. Fruit small, dry, separating into two 1-seeded pyrenes. 

 (In honor" of A. Lippi, a French traveler.) 



Species about 90, mostly American, single one in the Philippines, cer- 

 tainly introduced. 



1. L. NODIPLORA (L.) Rich. 



A creeping, minutely strigose plant, the stems 15 to 90 cm long, branched 

 and rooting at the nodes. Leaves nearly sessile, obovate, base wedge-shaped, 

 entire, the margins in the upper one-half sharply toothed, apex obtuse or 

 rounded, 1 to 2.5 cm long. Peduncles axillary, solitary, erect, 2 to 7 cm 

 long. Spikes ovoid or cylindric, very dense, 1 to 2.5 cm long, about 6 mm 

 in diameter. Corolla about 8 mm long, pink, the tube slender, the limb 2.'6. 

 mm wide or less, the spike flowering at the apex, as it lengthens. 



Common in waste places, lawns, etc., fl. all the year; throughout the 

 Philippines, certainly introduced. Tropics generally, probably originating 

 in tropical America. 



4. ST AC H YTA R P H ETA Vahl 



Erect, branched, suffrutescent herbs. Leaves opposite or alternate, 

 toothed. Spikes terminal, elongated, slender, the bracts long or short, 

 bracteoles none. Flowers solitary in the axils of the bracts, half-immersed 

 in the rachis of the spike. Calyx narrowly cylindric, 4- or 6-toothed. 

 Corolla blue, the tube slender, cylindric, the limb spreading, oblique, 5-lobed. 

 Stamens 2, included in the tube, 2 staminodes also present. Ovary 2-celled
