(John Sigismund Elsholtz, author of unpublished Flora Marchica, the MS. of which is in the Royal Library, Berlin). Labiatae. Herbs or undershrubs grown chiefly for their blue or lilac flowers appearing in dense spikes late in summer.

Usually aromatic: leaves opposite, short-petioled, serrate: flowers in usually 1-sided, terminal spikes; calyx tubular or campanulate, 5-toothed; corolla 2-lipped or slightly so; lower lip 3-lobed, the upper undivided, emarginate, concave; stamens 4, exserted; anther-cells diverging: fruit consisting of 4 ovoid or ovoid-oblong nutlets. - Twenty species in E. and Cent. Asia, south to Java, 1 in Eu. and 1 in Abyssinia. Of the cult, species E. cristata and E. Stauntonii are hardy N., while E. polystachya is tender. They are chiefly valued for their late-appearing flowers, profusely produced in dense upright spikes; they do not seem particular as to the soil, but demand a sunny position to bloom well. Prop, is by seeds, sown in spring; also with the suffruti-cose species by greenwood cuttings in summer.
