DIVISIÓN II. Regles y Encamientos. Capítulu III. Nomenclatura de los taxones acordies con el so rangu. Seición 1. Taxones penriba del rangu de familia. 16.1. The name of a taxon above the rank of family is treated as a noun in the plural and is written with an initial capital letter. Such names may be either (a) automatically typified names (Art. 10.7), formed from the name of an included genus in the same way as family names (Art. 18.1; but see Art. 16.4) by adding the appropriate rank-denoting termination (Art. 16.3 and 17.1), preceded by the connecting vowel –o– if the termination begins with a consonant; or (b) descriptive names, not so formed, which may be used unchanged at different ranks. Ex.1. Automatically typified names above the rank of family: Lycopodiophyta, based on Lycopodium; Magnoliophyta, based on Magnolia; Gnetophytina, based on Gnetum; Pinopsida, based on Pinus; Marattiidae, based on Marattia; Caryophyllidae and Caryophyllales, based on Caryophyllus; Fucales, based on Fucus; Bromeliineae, based on Bromelia. Ex.2. Descriptive names above the rank of family: Anthophyta, Chlorophyta, Lycophyta, Parietales; Ascomycota, Ascomycotina, Ascomycetes; Angiospermae, Centrospermae, Coniferae, Enantioblastae, Gymnospermae. (...) Note 2. The principle of priority does not apply above the rank of family (Art. 11.10; but see Rec. 16A). Recommendation 16A 16A.1. In choosing among typified names for a taxon above the rank of family, authors should generally follow the principle of priority. Códigu de Bacteries (Revisión 1990) Section 3. Naming of Taxa. Rule 8. The name of each taxon above the rank of order is a Latin or latinized word preferably in conformity with Recommendation 6. It is based by choice on a combination of characters of the taxon or from a single character of outstanding importance. Example: Kingdom—Procaryotae; Class—Schizomycetes. Rule 9. The name of a taxon between subclass and genus is formed by the addition of the appropriate suffix to the stem of the name of the type genus (see Rule 15). These suffixes are as follows: Table 1. Suffixes for Categories. Rank, Suffix, Example. Order, -ales, Pseudomonadales. Suborder, -ineae, Pseudomonadineae. Family, -aceae, Pseudomonadaceae. Subfamily, -oideae, Pseudomonadoideae. Tribe, -eae, Pseudomonadeae. Subtribe, -inae, PseudomonadinaeSection 4. Nomenclatural Types and Their Designation. Xeneral. Rule 15. A taxon consists of one or more elements. For each named taxon of the various taxonomic categories (listed below), there shall be designated a nomenclatural type. The nomenclatural type, referred to in this Code as "type," is that element of the taxon with which the name is permanently associated. The nomenclatural type is not necessarily the most typical or representative element of the taxon. The types are dealt with in Rules 16–22. Types of the various taxonomic categories can be summarized as follows:
