LXXXVm. VERBENACEiE— Vervain Order 



A natural order of herbs, shrubs, or trees. Leaves (except in a fevs^ genera) 

 opposite or whorled, entire toothed or incised-multifid, pinnate in one genus, 

 digitately compound in another. Stipules none. Flowers hermaphrodite, or 

 rarely polygamous by abortion, irregular or regular in a few genera, in 

 corymbs, spikes or heads, rarely solitary. Calyx tubular, persistent, inferior, 

 usually 5-toothed or lobed. Corolla gamopetalous, the tube often incurved 

 and cylindrical ; limb 5-4-cleft, with equal lobes, or more or less 2-lipped. 

 Fertile stamens 4, didynamous, or only 2. Ovary superior, sessile, termina- 

 ting in a simple style. Fruit more or less drupe-like or rather capsular, 2-4- 

 celled, each cell with one seed. 



About 700 species belong to this order and are chiefly natives of the 

 warmer parts of the globe. Only the genera and species described below are 

 hardy enough for outdoor gardening in the British Islands. 



LANTANA. — A genus containing much-branched, more or less prickly 



stems, which form in old plants, especially 

 if the tips have been pinched out, fine 

 bushes 3-5 ft. or more high. Leaves 

 ovate or oblong, pointed, wrinkled and 

 toothed, of a deep green, and emitting a 

 rather disagreeable smell when bruised. 

 Flowers in summer, numerous, collected 

 in round heads on stiff staUis thrown well 

 above the foliage, colour at first clear 

 yellow, passing into golden- or orange- 

 yellow, afterwards tinged with red. Fruit 

 a roundish, drupe-like berry, black when 

 ripe, and containing 2 stony seeds. 



This is the species from which the 



40-50 species of downy or hairy shrubs 

 or herbs, with an erect or climbing habit. 

 Leaves opposite, toothed, often wrinkled. 

 Flowers red, orange, white, or variously 

 coloured, in stalked, axillary heads. 

 Calyx small, membranous, truncate or 

 sinuate-toothed. Corolla tube cylindrical, 

 slender, with a spreading 4-5-lobed, equal 

 or obscurely 2-lipped limb. Stamens 4, 

 didynamous. Ovary 2-ceUed. Fruit 

 drupe-like.
