Abstract

Ludwigia peploides (Kunth) P.H.Raven - Floating primrose-willow - is native to wetlands of North, Central, and South America, and widely distributed across Africa, Australia, and Asia, and in Europe, where it is listed by EU Regulation no. 2016/1141 as an Invasive Alien Species (IAS) of Union concern. A photograph of the species from Romania taken in the Sai River Valley (Teleorman County) was published on the Facebook online platform in 2018. This first record, however, lacked further details on the observed specimen or any accompanying herbarium material that would ascertain its correct taxonomic assignation. By carrying out our own field surveys between October and November 2020 we hereby confirm the presence of the species Ludwigia peploides as a new addition to the Romanian alien flora. We identified many specimens occurring along the Sai River Valley, between Olteanca and Turnu Magurele localities. We further present preliminary data regarding the distribution, affected habitats, and population extent of Ludwigia peploides in the investigated area. Although several hypotheses can be proposed on the origin of this species in Romania, our current data cannot strongly support any of them. Plant specimens were deposited in the Herbarium collection of the D. Brandza Botanic Garden of the University of Bucharest (BUC).

罗马尼亚第一个可确定的人路德维希菌记录

渡鸦——漂浮的樱草柳——原产于北美洲、中美洲和南美洲的湿地，广泛分布于非洲、澳大利亚和亚洲，以及欧洲。2016/1141作为欧盟关注的外来入侵物种(IAS)。2018年，Facebook在线平台上发布了一张在罗马尼亚西河谷(泰奥曼县)拍摄的该物种的照片。然而，这第一个记录缺乏观察标本的进一步细节或任何随附的植物标本室材料，以确定其正确的分类定位。通过在2020年10月至11月期间进行我们自己的实地调查，我们在此确认该物种的存在，该物种是罗马尼亚外来植物群的新成员。我们在Olteanca和Turnu Magurele地区之间的Sai河流域发现了许多标本。本文还对调查区人路德维希蝇的分布、受影响生境和种群范围进行了初步分析。虽然可以提出几种关于该物种在罗马尼亚起源的假设，但我们目前的数据不能有力地支持其中任何一种。植物标本存放在布加勒斯特大学(BUC) D. Brandza植物园的植物标本馆。

期刊介绍： Contributii Botanice is an international, peer-reviewed journal publishing scientifically sound papers in the fields of Plant Systematics, Phytosociology, Plant Physiology and Morphology, Plant Ecology, Population Ecology, Ecosystem Ecology, Phytogeography, Phytopathology, Microbiology, Paleobotany, Plant Conservation and Cell/Molecular Plant Biology. Papers of mostly taxonomic nature or focussed on floristics and phytosociology will only be considered if they exceed the pure descriptive approach and have relevance interpreting patterns in the above mentioned plant sciences.
