Leucanthemopsis alpina (L.) Heywood (Asteraceae, Anthemideae) is a small, caespitose plant growing in high alpine environments in all the main southern European mountain ranges. However, the species status in the Balkan Peninsula (and especially in the Dinaric Alps) is not very well known. Surrounding this area, different L. alpina subspecies are found in the Eastern Alps and in the Carpathians. These subspecies differ from one another, both morphologically and in chromosome number. The present study aims to better characterise the populations of L. alpina in the Illyrian and Balkan regions by undertaking a comprehensive survey of herbarium collections for the species in this area, by applying flow cytometry for ploidy determination and by sequencing of two chloroplast markers. Results from our investigation suggest that the only population of the species in the Dinaric Alps is found in the Vranica Mts (Bosnia and Herzegovina). This population consists of diploid plants (unlike tetraploid populations from the Eastern Alps) that are slightly distinct genetically from those of the subspecies growing in the Eastern Alps and the Tatra Mts. Both the ploidy and their genetic distinction indicate that Vranica Mts most probably served as a refugium for the species during the Pleistocene glaciations. Considering its isolated geographical range and its genetic distinction, the population of L. alpina growing in the Vranica Mts should be considered as a separate subspecies.

在伊利里亚地区生长的白叶白粉病（L.）Heywood上

阿尔卑斯白菜（L.）Heywood（菊科，Anthemideae）是一种小型的鞘翅目植物，生长在欧洲南部所有主要山脉的高山环境中。但是，巴尔干半岛（尤其是迪纳里克阿尔卑斯山）的物种状况不是很清楚。在该地区周围，在东部阿尔卑斯山和喀尔巴阡山脉发现了不同的L. alpina亚种。这些亚种在形态和染色体数目上都互不相同。本研究旨在通过对该区域物种的植物标本室收集物进行全面调查，应用流式细胞仪进行倍性测定以及对两个叶绿体标记进行测序，从而更好地表征伊利里亚和巴尔干地区的高山被孢子种群。我们的调查结果表明，在迪纳里克阿尔卑斯山的唯一物种种群是在弗拉尼察山（波斯尼亚和黑塞哥维那）中发现的。该种群由二倍体植物组成（不同于东阿尔卑斯山的四倍体种群），这些植物在遗传上与在东阿尔卑斯山和塔特拉山上生长的亚种的基因略有不同。倍性及其遗传上的区别都表明，在更新世冰川期，弗拉尼卡山很可能是该物种的避难所。考虑到其孤立的地理范围和遗传差异，应将在弗拉尼察山上生长的高山乳杆菌种群视为一个单独的亚种。该种群由二倍体植物组成（不同于东阿尔卑斯山的四倍体种群），这些植物在遗传上与在东阿尔卑斯山和塔特拉山上生长的亚种的遗传上略有不同。倍性及其遗传上的区别都表明，在更新世冰川期，弗拉尼卡山很可能是该物种的避难所。考虑到其孤立的地理范围和遗传差异，应将在弗拉尼察山上生长的高山乳杆菌种群视为一个单独的亚种。该种群由二倍体植物组成（不同于东阿尔卑斯山的四倍体种群），这些植物在遗传上与在东阿尔卑斯山和塔特拉山上生长的亚种的遗传上略有不同。倍性及其遗传上的区别都表明，在更新世冰川期，弗拉尼卡山很可能是该物种的避难所。考虑到其孤立的地理范围和遗传差异，应将在弗拉尼察山上生长的高山乳杆菌种群视为一个单独的亚种。
