(ancient Greek name, used by Pliny for the horse-tail). Gnetdceae. Woody subjects, rarely cultivated; usually found only in botanical collections, although the scarlet fruits of some species are very attractive.

Usually low much-branched shrubs, often procumbent and sometimes climbing, the green branches resembling much those of Equisetum, bearing minute, scale-like, sheathing leaves in distant pairs or whorls: flowers dioecious, in small aments, forming usually peduncled axillary clusters; staminate flower with a 2-4-lobed perianth and with the 2-8 stamens united into a column; pistillate flower with an urceolate perianth, including a naked ovule, developing into a nutlet; in some species the bracts of the ament become fleshy, and form a berry-like syncarp. - About 30 species from S. Eu., N. Africa, Asia and in tropical Amer. Latest monograph by O. Stapf, in Denkschr. Akad. Wissensch. Wien., vol. 56 (1889), (in German and Latin). Curious-looking, usually low shrubs, with pale green apparently leafless branchlets, much resembling those of the horse-tail and with inconspicuous flowers, but fruit in some species decorative, berry-like and scarlet. They are but rarely grown, and most of them are tender; half-hardy N. are E. distachya, E. foliata, E. nevadensis, E. trifurca. They can be used for covering dry, sandy banks or rocky slopes.
