Haematoxylon campechianum
(species Haematoxylon campechianum), tree of the pea family (Fabaceae), native to Central America and the West Indies. The name is sometimes applied also to Condalia obovata, a tree of the buckthorn family (Rhamnaceae) native to southwestern North America. H. campechianum grows 9–15 m (30–50 feet) tall and has a short, crooked trunk. The leaves are pinnately compound (feather-formed), with rather oval leaflets. The small yellow flowers grow in a cluster from the leaf axil (upper angle between branch and leaf stem). The wood is heavy and extremely hard. A black dye, also called logwood, is obtained from the heartwood.
