A revision of the syntaxonomy of the Apennine-Balkan <i>Quercus cerris</i> and <i>Q. frainetto</i> forests and correct application of the name <i>Melittio-Quercion frainetto</i>.

<i>Melittio-Quercion frainetto</i> and <i>Melittio-Quercion confertae</i> are two alliances, which were proposed about simultaneously 40 years ago through two different papers regarding southern Italy and southern Greece, respectively. The aims of this paper are to establish valid name, nomenclatural type and distribution range of these two alliances and to verify whether they display a sufficient degree of syntaxonomic autonomy when compared to the ecologically and geographically neighbouring alliances. A data matrix composed of 43 frequency columns summing 1242 phytosociological relevés x 625 taxa was prepared and statistically analysed. The results suggested that the thermophilous <i>Quercus cerris</i> and <i>Q. frainetto</i> oak woods of the southern Apennines and the southern Balkans deserve to be classified in two separated alliances. The application of the principle IV of ICPN established that the correct name of the alliance is <i>Melittio albidae-Quercion frainetto</i> Barbéro, Bonin, Gamisans et Quézel in Bonin et Gamisans 1976 and that it was typified in southern Italy. Accordingly, the new name <i>Geranio asphodeloidis-Quercion frainetto</i> is here proposed for southern Greece in substitution of <i>Melittio-Quercion confertae</i> (<i>nom. illeg</i>.). The syntaxonomic proposal advanced in this paper brings significant modifications in the current version of the checklist of the European syntaxa (Eurovegchecklist).<i>Melittio-Quercion frainetto</i> 与 <i>Melittio-Quercion confertae</i> 为两个群丛组（alliance），二者于约40年前，分别通过针对意大利南部与希腊南部的两篇独立研究论文被同时提出。本研究旨在明确这两个群丛组的合法名称、命名模式与分布范围，并验证相较于生态及地理相邻的群丛组，二者是否具备足够的群丛分类自主性（syntaxonomic autonomy）。本研究构建了包含43个频度列、总计1242个植物社会学样方（phytosociological relevés）与625个分类单元（taxa）的数据矩阵，并进行了统计分析。结果显示，南亚平宁半岛与南巴尔干半岛的耐热土耳其栎（<i>Quercus cerris</i>）与匈牙利栎（<i>Q. frainetto</i>）栎林，应被划分为两个独立的群丛组。依据国际植物群丛分类命名法规（International Code of Phytosociological Nomenclature, ICPN）的第四条原则，该群丛组的正确名称应为<i>Melittio albidae-Quercion frainetto</i> Barbéro, Bonin, Gamisans et Quézel in Bonin et Gamisans 1976，其命名模式指定于意大利南部。据此，本研究为希腊南部提出新名称<i>Geranio asphodeloidis-Quercion frainetto</i>，以替代原非法学名<i>Melittio-Quercion confertae</i>（<i>nom. illeg</i>）。本研究提出的群丛分类修订方案，对现行欧洲句法类群名录（Eurovegchecklist）版本作出了重要修订。
