It is native to tropical America, from Mexico through Central America, Florida, the Caribbean, and northern South America. It has been introduced to other tropical areas of the world. It is currently threatened by habitat loss in its native region, and as such, is currently rated near threatened on the IUCN Red List. ''Guaiacum sanctum'' is the national tree of the Bahamas. Etymology The native Taíno of the Caribbean referred to the tree as guayacán. The common English name is a direct translation of the Spanish "palo santo" (not to be confused with ''Bursera graveolens'').

In the 19th century trees growing along the outskirts of this region were so small they were described by the United States Department of Interior as "low shrub(s)". The largest examples could be found on the hillsides near the Guadalupe river valley. Description Texas lignum-vitae is a many branched shrub or small tree, reaching a height of . This evergreen has a dense canopy and short lateral branches. Leaves Leaves ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Guaiacum Officinale
''Guaiacum officinale'', commonly known as roughbark lignum-vitae, guaiacwood or gaïacwood, is a species of tree in the caltrop family, Zygophyllaceae, that is native to the Caribbean and the northern coast of South America. Description This small tree is very slow growing, reaching about in height with a trunk diameter of . The tree is essentially evergreen throughout most of its native range. The leaves are compound, in length, and wide. The blue flowers have five petals that yield a bright-yellow-orange fruit with red flesh and black seeds. Symbolism ''Guaiacum officinale'' is the national flower of Jamaica. Uses ''Guaiacum officinale'' is one of two species yielding the true lignum vitae, the other being ''Guaiacum sanctum''. Guaiac, a natural resin extracted from the wood, is a colorless compound that turns blue when placed in contact with substances that have peroxidase activity and then are exposed to hydrogen peroxide.

Lignum Vitae
Lignum vitae () is a wood, also called guayacan or guaiacum, and in parts of Europe known as Pockholz or pokhout, from trees of the genus ''Guaiacum''. The trees are indigenous to the Caribbean and the northern coast of South America (e.g: Colombia and Venezuela) and have been an important export crop to Europe since the beginning of the 16th century. The wood was once very important for applications requiring a material with its extraordinary combination of strength, toughness, and density. It is also the national tree of the Bahamas, and the Jamaican national flower. The wood is obtained chiefly from ''Guaiacum officinale'' and ''Guaiacum sanctum'', both small, slow-growing trees. All species of the genus ''Guaiacum'' are now listed in Appendix II of CITES (the Convention on International Trade in Endangered Species of Wild Fauna and Flora) as potentially endangered species. ''G. sanctum'' is listed as Near Threatened by the IUCN Red List. Demand for the wood has been reduc ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Plants in the family Zygophyllaceae may be trees, shrubs, or herbs. They are often found in dry habitats. The leaves are usually opposite, often with stipules and spines. Some are cultivated as ornamental plants, such as species of the ''Guaiacum'', ''Zygophyllum'', ''Tribulus'', and ''Larrea'' genera. i L. Watson and M.J. Dallwitz (1992 onwards).

Floral Emblem
In a number of countries, plants have been chosen as symbols to represent specific geographic areas. Some countries have a country-wide floral emblem; others in addition have symbols representing subdivisions. Different processes have been used to adopt these symbols – some are conferred by government bodies, whereas others are the result of informal public polls. The term floral emblem, which refers to flowers specifically, is primarily used in Australia and Canada. In the United States, the term state flower is more often used. National plants Africa Mauritius The national flower of Mauritius is '' Trochetia boutoniana''. Seychelles The national flower of the Seychelles is the tropicbird orchid (known locally as ''orkid payanke''), '' Angraecum eburneum''. South Africa The national flower of South Africa is the King Protea, ''Protea cynaroides''. Tunisia The national flower of Tunisia is jasmine.

CITES
CITES (shorter name for the Convention on International Trade in Endangered Species of Wild Fauna and Flora, also known as the Washington Convention) is a multilateral treaty to protect endangered plants and animals from the threats of international trade. It was drafted as a result of a resolution adopted in 1963 at a meeting of members of the International Union for Conservation of Nature (IUCN). The convention was opened for signature in 1973 and CITES entered into force on 1 July 1975. Its aim is to ensure that international trade (import/export) in specimens of animals and plants included under CITES, does not threaten the survival of the species in the wild. This is achieved via a system of permits and certificates. CITES affords varying degrees of protection to more than 38,000 species. , Secretary-General of CITES is Ivonne Higuero. Background CITES is one of the largest and oldest conservation and sustainable use agreements in existence. There are three working langu ...

Flowering Plant
Flowering plants are plants that bear flowers and fruits, and form the clade Angiospermae (), commonly called angiosperms. The term "angiosperm" is derived from the Greek words ('container, vessel') and ('seed'), and refers to those plants that produce their seeds enclosed within a fruit. They are by far the most diverse group of land plants with 64 orders, 416 families, approximately 13,000 known genera and 300,000 known species. Angiosperms were formerly called Magnoliophyta (). Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds. The ancestors of flowering plants diverged from the common ancestor of all living gymnosperms before the end of the Carboniferous, over 300 million years ago. The closest fossil relatives of flowering plants are uncertain and contentious. The earliest angiosperm fossils ar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
