"This website attempts to present all currently accepted generic, specific, subspecific and variety names of trees, excluding fossil, extinct taxa, hybrids and cultivars. The definition of a tree follow essentially Little Jr. (1979: 3). A tree is defined as a woody plant, with a single, erect and persistent stem of at least 10 cm in diameter, mesured at 1.3 m above the mean ground level, and with a total height of at least 5 m. A crown of leaves may be more or less well defined. Willows (Salix), birches (Betula), palms (Palmae) and bamboos (Bambusa, Guadua), with several stems branching from the same root system, as well as cacti (Cactaceae) are considered as trees, provided that they meet the diameter and height criteria. Only the indigenous trees of a continent, those wild species that were natural elements of the spontaneous forest vegetation before the arrival of Europeans or other colonizers are included. Each entry includes the family to which it is assigned, the synonyms of Latin name, the English names, the French names, the Spanish names and other names. For English and French names, the standard name is listed first. This name is then followed by other available names with the country where they are used in parentheses. Where additional names are listed, the parentheses indicate the language and the country where they are used. Each infrageneric (species, subspecies, variety) entry includes the distribution, height, type of foliage, ecological characteristics and main uses of the tree when available. These informations are followed by synonyms, and English, French, Spanish and other names presented in the same manner as in the case of a genus. Abbreviations for authors' names follow Brummitt & Powell (1992). In this part of the website only taxa indigenous on the North American continent are included. North America is comprised in the global geographical and not political sense. That means from Alaska and Greenland to Panama, including Caribbean, but excluding Hawaii."
