(Greek, lovely flower). Acantha-cex. Tropical shrubs and sub-shrubs, some of which are cultivated chiefly for their foliage and others for their flowers.
Leaves entire or rarely coarsely toothed: flowers white, lilac, rosy or red, borne in various ways; bracts and bractlets narrow, small; corolla-tube long, slender, cylindrical throughout or rarely with a short throat; limb 5-parted; stamens 2; ovules 2 in each cell; seeds 4 or fewer. - Perhaps 30 species. The genus Daedala-canthus, although in a different tribe, is separated only by a combination of technical characters, but the garden forms of both genera described in this work are.all distinguishable at a glance. for cultivation, see Jus-ticia. Consult Daedalacanthus for related species.

The following trade names belong to plants grown chiefly for their foliage. Probably many of them belong in other genera. - E. albo-marginatum. Leaves broadly margined with white and irregularly suffused gray. - E. atrosanguineum, Hort. Intro, by W. Bull, 1875. Leaves large, dark, wine-purple, or blackish crimson, ovate entire, opposite, stalked. Said to endure the hottest sunshine. - E. cultratum. "Leaves shining, thick, deep-veined." - E. Dutremblayanum, Hort., is supposed to be a garden hybrid. Intro, from France in 1907. - E. Eldorado. Leaves greenish yellow, veins deeper yellow. - E. igneum. G.W. 3, p. 159. See Cham-seranthemum. - E. Magneanum, Hort., is recorded as a garden hybrid. Intro, from France 1907. Scarcely known in U. S. - E. nerium rubrum presumably a misprint for nervum-rubrum, has leaves "irregularly shaped, shaded with light and dark green, and blotched with yellow, which darkens to reddish purple." Possibly=Fittonia Verschaffeltii. - E. nervosum=Daedalacanthus nervosus, T. Anders. - E. nigrescens.
Presumably with blackish leaves - E. pulchellum, Hort, and Andr.=Dsedalacanthus nervosus, T. Anders,. - E. pur-pitreum. "Leaves and stems dark, lurid purple." Siebrecht & Wadley. - E.
