This dictionary attempts to present, in alphabetical order of the currently accepted Latin names, all known genera, species, subspecies and varieties of trees, excluding fossil and more recently extinct taxa, hybrids and cultivars. Separated indexes of Latin synonyms, English, French, Spanish, and other possible names and trade names are also provided. All taxa are numbered consecutively. This last number appears in all indexes permitting rapid and easy cross-referencing.

The definition of a tree follows 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, measured 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 generic entry includes the family, according to Cronquist (1981) as modified by Mabberley (1993), to which the genus is assigned, the synonyms of Latin name, and English, French, Spanish, trade and other names. For English and French names, the standard name is listed first, followed, in alphabetical order, by additional available names, transcribed such as they were found in literature, with the country where they are used in parentheses. Where the names in other languages are listed, the parentheses indicate the language and the country where they are used.

Each infrageneric (species, subspecies, variety) entry includes, in addition, the distribution, height, type of foliage, ecological characteristics and main uses of the tree when available. Please note that the content of the section dr is for informational purposes only. The author is not liable in any way for the results of medicinal uses mentioned in this book. The reader assumes any and all risk of damage, injury, death, or any other inconvenient related to the content found herein.

Abbreviations for authors' names follow Brummitt & Powell (1992).

In this first volume only taxa native to 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 the Caribbean, but excluding Hawaii. It is divided into 9 zones (Figure, p. xiv).

For users unfamiliar with the condensed style of dictionaries such as this, the following generic and specific name entries are set out in extenso as examples to aid comprehension.
