a genus of woody plants or shrubs of the family Agavaceae. There are about 150 species in the tropics and subtropics of the eastern hemisphere. The stems are branched; the leaves are linear or lanceolate, and the flowers are usually in panicles, with a simple, six-lobed white or yellowish perianth, six stamens, and pistils with three nidi. The fruit is a berry. The bark of certain species, such as the dragon tree, exudes a resinous red substance that is used to make lacquers. Many species, particularly those with varie-gated leaves (D. godseffiana, D. deremensis, and others), are raised in hothouses and indoors.
