Order Cxvi
VERBENACEÆ.
A mixture of weeds and shewy herbs, of humble creeping plants and of lofty timber trees. Some of the Vitexes and Clerodendrums are handsome shrubs: Aloýsia is esteemed for the fragrance of its flowers, and Holmskióldia for the refulgent scarlet of its enlarged calyxes. Téctona produces the famous Indian teakwood. No properties of consequence have been attributed, by medical men, to any plant of the order, those formerly ascribed to the vervain and chaste-tree being now disregarded. The species are natives of waysides in Europe, and of woods and barren plains in the tropics. 1322 Verbéna L. 54 Stachytárpheta Vahl 1319 Zapánia J. 1320 Príva P.

ACANTHACEÆ.
These are known by the elastic dehiscence of their capsules, and the hooked processes of the seeds. They are almost entirely tropical herbs or shrubs, with the pubescence, if any, simple or capitate, but never stellate. Their leaves are opposite, occasionally arranged in fours, simple and undivided, or very seldom lobed. The flowers are either in imbricated heads or open racemes, always enclosed in their bracteæ; and are white, blue, yellow, scarlet, or purple. Some of the species are very shewy, but few of them are cultivated commonly; a large proportion are mere weeds. The Thunbérgias are fine climbers, and the Acánthus móllis, the foliage of which gave rise to the classical acanthus of architecture, is, perhaps, except Morína pérsica, one of the most interesting of hardy herbaceous plants. It is also one of the few species to which any medical properties are ascribed, being used sometimes as an emollient by reason of its mucilage. Justícia biflóra is employed in Egypt as a poultice, J. Ecbólium as a diuretic, and J. pectorális as a vulnerary. 45 Elytrária M. 46 Hypoéstes R. Br. 47 Justícia W. 49 Eránthemum P. B. 1302 Barléria W. 1303 Phaylópsis Juss. 1304 Ruéllia J. 1305 Bléchum R.

ORDER CXVIII.
LENTIBULARIÆ.
Very pretty interesting aquatics, which are scarcely susceptible of cultivation, except in a few cases. The Pinguículas are either European or North American, inhabiting elevated patches in bogs: the Utriculárias are floaters, found in most countries in marshes and little rills: their flowers, are white, yellow, or blue. 52 Pinguícula W. 3Z4 53 Utriculária W.
