Flora of Spain and the Balearic Islands. Checklist of Vascular Plants. Part 1: Pteridophyta, Gymnospermae, Acanthaceae- Crassulaceae. 1984. (Englera, Vol. 3, no. 1). XXXIII,212 p. gr8vo. Paper bd.

From the introduction: This checklist has been compiled using Flora Europaea as a basis, but giving a reference to the serial number of the species in the work of Willkomm & Lange. The taxonomy is that of Flora Europaea except where generic revisions have been published later than the Flora Europaea account, and an effort has been made to take note of all such work published down to the end of 1980. Every serial number in Willkomm & Lange, and in Willkomm's Supplementum, has been accounted for, but where the species concerned is now known to be absent from Spain, or present only in cultivation, it is placed in square brackets to indicate that it is not part of the native or naturalized flora of Spain... The families in this Spanish checklist are those set out in Med-Checklist Document n. 6 (March 1979), and the order is alphabetical throughout, i.e. within each of the four major groups (Pteridophyta,Gymnospermae, Dicotyledones, Monocotyledones) the families are in alphabetical order, with genera in alphabetical order in each family,and species in each genus. - Treatment of hybrids: As a rule these are included only if they have a separate serial number in Willk. & Lange or in Flora Europaea. - Geographical information: There are four main categories of plants in Spain: 1. Iberian endemics, 2. Plants that are not found elsewhere in Europe but occur in N Africa, 3. Plants that are restricted to the area covered by Flora Europaea and Med.-Checklist, 4.Plants that are more widespread, extending into Asia or Africa, or are cosmopolitan. In this checklist the first two categories are distinguished by symbols; categories 3 and 4 are distinguished by the use of "etc.", which implies category 4. The distribution within Spain is only indicated in general terms by abbreviations (N,S,etc.), which refer to parts of Spain indicated on map n. 2, the boundaries of these subdivisions being the same as were used in Flora Europaea.
