So called by Linnæus, from τρiβω, to bruise or crusi, in allusion to the purpose to which its grain may be applied. Forage grasses of the West Indies. 1953. Heteropogon. From ἑτερoς, various, and πωγωv, a beard; in allusion to the various kinds of awns with which the flowers are furnished. 1954. Olyra. A name under which Homer speaks of a grain which was used as the food of horses, and which has been thought analogous to Barley. The plant now so called is a native of America, and has no resemblance to that of the ancients. 1955. Alnus. From the Celtic word al, near, and lan, the edge of a river, in reference to the places where the species grow. A. glutinosa, Aulne, Fr., Eller, Ger., and Alno, Ital., is a well known timber tree, which will grow in marshy situations. The timber is applied to a variety of purposes, and in general for all works intended to be constantly under water, for turnery and furniture. The bark is used by dyers and tanners; the sap being of a yellow color and very astringent. There is a variety with cut leaves sold by the nurserymen as an ornamental tree, though it is more curious than showy. 1956. Betula. Betu is the Celtic word for the Birch. Bouleau, Fr., Birchenbaum, Ger., and Betulla, Ital. B. pendula is the most graceful tree of the genus; it grows both in mountainous situations and bogs, from Lapland to the subalpine parts of Italy and Asia. B. lenta, the mahogany birch, mountain mahogany, or cherry birch of Canada, abounds in the middle states of Pennsylvania, New York, and the Jerseys; but disappears altogether in the higher latitudes of the northern states. It is thought a very fit tree for planting in the valleys of the mountainous districts of Britain. Its growth is rapid, and the timber is close grained, beautifully variegated, and well adapted for cabinet work. The leaves, which appear early in spring, possess ORDER III.

B. populifolia and papyracea are elegant rapid growing trees, well deserving culture for their timber. All the species are ornamental, and more or less fragrant; and B. pumila and nana are pretty little shrubs. Of the Betula papyracea the North American Indians construct their large portable canoes, from which circumstance that species is known by the name of canoe birch. Betula lenta is the most interesting of the genus, on account of the excellence of its wood. It is known by the names of mountain mahogany, black birch, cherry birch, and sweet birch. This last appellation it has from the sweet scent the branchlets give when bruised. 1957. Buxus. An alteration of πuξoς, its Greek name. B. sempervirens, Buis, Fr., Buchsbaum, Ger., and Bosso, Ital. is one of the most useful of evergreen shrubs; edgings of the dwarf variety are of universal use in the walled gardens of Europe; and what is called the tree box is not less valuable as an evergreen shrub, which will grow under the shade and drip of trees. The box is a native of most parts of Europe, from Britain southwards, and is very abundant in different parts of France and Switzerland. It abounds in many countries of Asia, as about Mount Caucacus, in Persia, China, Cochin China, and America. It was formerly very cominon in England, but has gradually disappeared as agriculture extended. Box-Hill in Surrey, Boxley in Kent, and Boxwell in Gloucestershire, are named from their abounding in this tree. The timber of the box tree is of considerable value. It is sold by weight, and being very hard and smooth, and not apt to warp, is very well adapted to a variety of nicer works. It is as extensively employed now as it appears to have been in the days of Evelyn, " for the turner, engraver, carver, mathematical instrument maker, comb and pipe or 1958. CIC/CA. W.
