Guaiacum sanctum, commonly known as Holywood or Holywood Lignum-vitae, is a species of flowering plant in the creosote bush family, Zygophyllaceae. It ranges from southern Florida in the United States and the Bahamas south to Central America and the Greater Antilles.[2] It is threatened by habitat loss.
This tree is one of two species which yield the valuable Lignum vitae wood, the other being Guaiacum officinale. This small tree is slow growing, reaching about 7 m (23 ft) in height with a trunk diameter of 50 cm (20 in). The tree is essentially evergreen throughout most of its native range. The leaves are compound, 2.5–3 cm (0.98–1.18 in) in length, and 2 cm (0.79 in) wide. The purplish blue flowers have five petals each, and yield yellow pods containing black seeds encapsulated separately in a red skin.
Guaiacum sanctum is the national tree of the Bahamas.[3]

Antecedentes del estado de la especie o de las poblaciones principales
Esta especie se distribuye naturalmente a lo largo del arco occidental en la amplia región del Caribe. Desde el sur de América Central hacia el norte y el este a través de las Grandes Antillas, y más hacia el norte desde Costa Rica a México, Bahamas, Española, Puerto Rico, Cuba y el sur de Florida (USA). Con poblaciones dudosas en Belice y Panamá. La sobrexplotación durante casi 500 años ha disminuido drásticamente las poblaciones de la especie al punto de ser considerada extinta o extremadamente rara en la mayoría de las islas del Caribe. En América Central y la Florida permanecen poblaciones relictuales bajo amenaza por la pérdida de su hábitat y explotación. También se sabe que se encuentra amenazada en otros 11 países que comprende su rango de distribución, sin embargo no fue incluida en la IUCN Red List of threatened plants, 1997. Las poblaciones de Cuba son las más abundantes y no están decreciendo (U.S. fish and Wildlife Service, 2000).

Comments: Authors disagree on spelling of genus name; some spell "Guaiacum" (Little, 1978, and Elias, 1980). Kartesz (1994) spells "Guajacum", which follows rule in code of nomenclature: Linnaeus wrote "Guajacum" in his Species Plantarum, and "Guaiacum" in his Genera Plantarum; according to the code of nomenclature the name in the Species Plantarum supersedes.
