3.0. REGULATIONS

3.1. Quotations of authors

The use of abbreviations in quoting the author of the species has been standardised according to the abbreviations given in the Appendix I in TUTIN et al. (1968-1980, 1993), and KEW BOTANICAL GARDEN (1980).

3.2. Quotations of publications

The use of the abbreviations of publications has been standardised in accordance with the Appendices II and III in TUTIN et al. (1968-1980, 1993) and, if necessary, with some abbreviations from the lists (e.g. ALKIRE, 1977; LEISTNER, 1977; PUGH, 1981; MOSSMAN, 1991).

The Check-list shall use the abbreviated version of bibliography quotiation, such as:

Acta Bot. Croat. 40: 245-250 (1981)

The Check-list is accompanied by the bibliography including full quotes of the titles according to the Harvard concept (SILOBRC 1989) for some taxa only (see 4.0.) and is indexed according to the names of the species it refers to.

3.3. Synonyms

The aim of the Check-list does not include providing full synonyms for each taxa. The synonyms, either complete or partial, are only provided for the species with which it is neccessary to prevent the potential misunderstandings. The synonyms (or basionyms) are also usually given when the combination has not previously been used in the floras or monographs (this mostly refers to the species described in Croatia).

3.4.Taxa

The Check-list includes the following taxa: family (familia), genera (genus), species, and subspecies.

3.5.Treatment of critical groups

The groups of closely related species are marked in the Check-list as an aggregate, eg. the Pulsatilla species.

Pulsatilla alpina agg. which includes the species P. alba Reichenb., P. alpina (L.) Delarbre i P. apiifolia (Scop.) Schult.

Agregates do not hold the taxonomic and nomenclatural status. The treatment of the critical groups fully depends on the author of a particular study.

3.6. Treatment of hybrides

Hybrides from the closely related species are only sometimes quoted:

1.- when their frequence is estimated as significant
2.- when they occur at relatively large surfaces.

The names of hybrides follow the nomenclature rules of Article 40 of the Code. They are marked by an extensive method.

Q. alba L. X Q. michauxii Nutt,

and the binominal name is quoted in the brackets

Quercus X beadlei Trel.

3.7. Treatment of foreign species

The Check-list includes only those foreign species which satisfy the following criteria:

A - only efficiently naturalised species. This includes the species which have "escaped" the horticulture (gardens) and grow at stands that are not in the immediate vicinity of the location where they had been cultivated, as well as the species introduced by seeds. The reports are required to show that the taxa are naturalised at one or several separated locations.

B - trees and plants cultivated at larger spaces and to a significant extent.

The species that can not survive without constant implementation do not enter the Check-list with the exception of the occurrence of hybridisation with the domestic species or for some other reason. The nomenclature of the foreign species, especially the cultivated ones, should be dealt with according to Article 28 of the Code (BRICKELL 1980, VOSS 1983, GREUTER and HIEPKO 1989).
