Buxus (Box Tree). Euphorbiaceæ.
Propagated by seeds sown as soon as ripe, in any light, well-drained soil. They can be increased by suckers and divisions; by layers of young or old wood, made in autumn or early spring; by cuttings made of the young shoots, from four to six inches in length, in a sandy place in spring or fall. The latter method is the better way in this country, and in the north the cuttings should be handled under glass.
Byrsonima. Malpighiaceæ.
Increased by cuttings of half-ripened shoots in sand under a hand-glass, in moist bottom heat.
