摘要
摘要 Harries, H.C.†, L. Pignotti & R.M. Baldini (2020)。Cocos nucifera f. palmyrensis (Arecaceae: Cocoseae).Candollea 75: 25-30.英文,英文摘要。北太平洋偏远的珊瑚环礁帕尔米拉岛上覆盖着丰富的赤道植被,其中椰子树林目前在其他地层中占主导地位,本文介绍了这些植被的主要特征。本文还简要回顾了历史上和近代人类活动的方式和时间,这些活动可能改变了原始植被。巴尔米拉椰子果实异常巨大,令美国植物学家约瑟夫-弗朗西斯-洛克(Joseph Francis Rock,1884-1962 年)惊叹不已,他将四颗果实寄给了佛罗伦萨著名的棕榈专家奥多尔多-贝卡里(Odoardo Beccari,1843-1920 年)。贝卡里对材料进行了描述,并于 1916 年将其作为 Cocos nucifera f. palmyrensis Becc.部分原始材料已在方济各会国际找到。目前仍保存在方济各会国际的两颗椰子果实中的一颗在此被指定为贝卡里名字的讲座原型,它在此被提升为变种,比目前孤立岛屿种群的概念更能反映其形式。帕尔米拉环礁及其椰子在椰子地理起源的古老争议中扮演了重要角色。贝卡里(Beccari)和埃米利奥-乔文达(Emilio Chiovenda,1871-1941 年)都引用了这一分类群来支持他们关于该物种起源于亚洲的假设。本文将根据现有资料简要讨论这些年代解释的意义。收到:2019年10月16日;接受:2020 年 2 月 4 日;首次在线发表:2020年3月24日
Unraveling the taxonomic identity of Cocos nucifera f. palmyrensis (Arecaceae: Cocoseae)

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.
