** Codes:

Origin: N=Native I=Introduced
Longevity: A=Annual B=Biennial P=Perennial
Season of Growth: W=Warm-season growth C=Cool-season Growth

The dististribution for each taxon is summarized by the numbers 1 through 10, representing the 10 vegetational areas of Texas.

** Methodology

The section titled "Texas Plants -- An Ecological Summary" includes a discussion of the vegetation types, dominant plant species, soils, and current land uses within the 10 vegetational areas of Texas which is from Gould et al. [1960]). The arrangement of families in the current version of the searchable database and the 1990 version of the checklist generally corresponds to the sequence given in Correll and Johnston (1970), which is a modified Engler and Prantl (1887-1915) alignment. Within a family, the genera, species, subspecies, and varieties are arranged alphabetically.

Correct names, shown in bold face in the original checklist, are listed as the first line of each record in the database. Appropriate synonyms, shown in italics in the original checklist, are provided as an indication of "Other names in use" in the database.

Users may notice an alteration in the spelling of several specific epithets. If the stem in a two-part specific epithet ends in a, e, o, or u, then such a vowel is deleted and replaced by o for Greek stems and by i for Latin stems. For example, iva : folia, written as ivifolia, as per Article 73G of the International Code of Botanical Nomenclature (1983), was previously written as ivaefolia. Authorities are given for genera, species, subspecies, and varieties (typical subspecies and varieties, called autonyms, do not have authorities). To conserve space, we have cited only the essential authorities instead of complete authorities; for example, the authority for Muhlenbergia asperifolia is given as (Trin.) Parodi, not as (Nees and Mey. ex Trin.) Parodi (allowed either way, as per International Code of Botanical Nomenclature, Article 46E; Voss et al. 1983).

Scientific names are followed by common names (if available) in the original checklist and listed as "local name" in the database. The first or only common name of a species is shown in all capital letters, and additional common names appear in lower case letters. The initial letters of common names of genera, if any, are capitalized. If the common name of a genus is used for the species, the name is abbreviated to its first letter.

A broad regional distribution is given for each species, subspecies, and variety. The codes for origin, habit (longevity), phenology, and distribution, given on the inside of the front cover of the checklist, are either translated as phrases in the database or listed as 'yes' or 'no' indications (a description of the 'translation' of the electronic files is.

Additions, corrections, and taxonomical changes (to Correll and Johnston 1970 and to Gould 1975b), indicated with asterisks (see the inside of front cover) in the checklist, are not specifically noted in the database, although later versions will carry this information. References for these recent revisionary works are given in the section titled "Bibliography." The references are provided in two categories: general and family.
