Abstract

Abstract Jacquemoud, F. & D. Jordan (2020). Androsace albimontana (Primulaceae): a new species from the Alps (France, Switzerland, Italy) to be distinguished from A. pubescens. Candollea 75: 149–155. In French, English and French abstracts. A new alpine species of the genus Androsace L. (Primulaceae), Androsace albimontana D. Jord. & Jacquemoud is described. Specimens attributed to the new taxon were until now considered by floras as being part of the high morphological and ecological variability of Androsace pubescens DC. (bi- to trifurcate vs simple trichomes, corolla mostly pink to rarely white vs white; acid, siliceous vs alkaline, calcareous substrate), a chasmophytic species growing exclusively on limestone cliffs. Morphology, habitat and ecology of the new taxon were determined in the siliceous mountain ranges of Aiguilles Rouges and Mont-Blanc (Haute-Savoie, France), and in Valais (Switzerland). Data from Italy (Monte Rosa, Valle d'Aosta, Piemonte) only provided by floras or botanical literature, will have to be subject of further field and herbarium studies. Distribution data are given, relationships with other species of Androsace subsect. Aretia (L.) Kress and the putative origin of the new taxon are discussed.

Androsace albimontana（Primulaceae）：来自阿尔卑斯山（法国、瑞士、意大利）的一个新种，与短柔毛A.pubescens不同

摘要Jacquemoud，F.&D.Jordan（2020）。报春花科（Androsace albimontana）：阿尔卑斯山（法国、瑞士、意大利）与毛报春花（a.pubescens）的一个新种。Candollea 75:149–155。法语、英语和法语摘要。报春花科Androsace L.属高山植物一新种，白花Androsace albimontana D.Jord.&描述了杰奎穆德。到目前为止，归属于新分类单元的标本被植物区系认为是毛雄蛛高度形态和生态变异的一部分。（二至三分叉与单毛状体，花冠大多为粉红色至很少为白色与白色；酸性、硅质与碱性，钙质基质），一种仅生长在石灰岩悬崖上的裂隙植物。在Aiguilles Rouges和Mont Blanc（法国上萨瓦省）以及Valais（瑞士）的硅质山脉中确定了新分类单元的形态、栖息地和生态。仅由植物区系或植物学文献提供的意大利（罗莎山、奥斯塔山谷、皮埃蒙特）的数据，必须进行进一步的野外和植物标本馆研究。文中给出了分布数据，以及与其他种的亲缘关系。讨论了Aretia（L.）Kress和新分类单元的假定起源。

期刊介绍： Candollea is an international peer-reviewed journal that publishes original scientific papers, preferably in English but also in French. Spanish language manuscripts will be evaluated only if linked to scientific projects involving the Conservatoire et Jardin botaniques de Genève. Successful submissions will be in the fields of evolution, molecular systematics, morphology-anatomy, nomenclature, taxonomy, or vegetation analyses of plants. Reviews and articles on the history of botanical collections are welcome. New distribution records lacking pertinent analyses will not be considered. Manuscripts dealing with nomenclature alone will be considered only if clearly related to the Geneva library or herbarium (G). Authors are encouraged to deposit duplicates of their material, especially nomenclatural types, at G.
