摘要
几个北极残种(蔓越莓、白桦)的西南边界分布在法国中部地块。虽然特别局限于少数残存的沼泽,但在块地中心的几个地方,双倍体(推测为V. microcarpum)显示出意想不到的细胞学多样性,有时与四倍体(推测为V. oxycoccos)混合生长。在法国,我们首次鉴定出了六倍体蔓越莓。这些植物对应于“四瓣氧可可”(Oxycoccos quadripetala (Gilib.) var. majuscula)。Chassagne是一个大型的、高度开花的湖泊沼泽先驱分类群。palustris var major Lange也是一种叶大的蔓越莓,但采集于奥斯陆附近。这两种植物分别于1957年在奥弗涅和1883年在斯堪的纳维亚被描述,它们被所有植物学家所忽视,在植物学文献中一直没有出现,这就是我们在这里将它们作为典型的原因。它们可能属于同一物种。然后,对蔓越莓的生态和进化有了新的认识。无论如何,这都突显了奥弗涅泥炭地的极度丰饶和原生态,这里现在是世界上已知的四种蔓越莓中的三种的家园:微果蔓越莓和氧可可蔓越莓(主要是原生泥炭地),以及apo地方性的蔓越莓(仅在原生泥炭地)。
Vaccinium majuscula (Chassagne) Fridl. in French Massif central and its related Scandinavian Oxycoccus palustris var major Lange.
The south-western limit area distribution of several arctic relict species (cranberries, Betula nana) occurs in the French Massif central. Although especially localised in a few relict bogs, Vaccinium sect. Oxycoccus show an unexpected cytological diversity with diploids (supposedly V. microcarpum) in several localities of the Massif central sometimes growing in mixture with tetraploids (putatively V. oxycoccos). For the first time in France, we identified hexaploid cranberries. These plants correspond to « Oxycoccos quadripetala (Gilib.) var. majuscula » Chassagne a large, highly floriferous pioneer taxa of lacustrian mires. Oxycoccus palustris var major Lange is also a large leaves cranberry but collected in the vicinity of Oslo. Respectively described from Auvergne in 1957 and from Scandinavia in 1883, these two plants have been ignored by all botanists and remained absent from botanical literature, which is why we typify them here. They could correspond to the same species. Then, a new ecological and evolutionary understanding of cranberries is possible. In any case, this underlines the extreme richness and originality of the Auvergne peatlands, which are now home for three species of cranberry among the four known in the world: V. microcarpum and V. oxycoccos (mostly ombrogenous peatland) and, the apoendemic V. majuscula (only in topogenous mire).
