A summer in Siberia: the travel and the collection itinerary to the mouth of the Ob River by the botanist and ethno-anthropologist Stéphen Sommier in 1880

Stéphen Sommier (1848–1922) was a renowned botanist, plant collector, ethnographer, geographer and photographer. He is best known for his scientific expeditions to Italy, Scandinavia and Russia. This study provides a detailed reconstruction of his travels and collections during the expedition he led to the mouth of the Ob River in Siberia in the summer of 1880. This voyage was of significant botanical importance, with 562 different plant taxa collected, 22 of which were described as new to science at the time. The voyage is also significant from an ethnological point of view, as Sommier was the first Italian scientist to encounter and document the various Siberian populations of the time. The places visited have been georeferenced and presented in a topographical map, which highlights the itinerary and the sites where specimens corresponding to taxa later described as new to science were collected.

斯特凡·索米耶（Stéphen Sommier，1848–1922）是享誉学界的植物学家、植物采集家、民族志学者、地理学家与摄影师。其最为人熟知的科研考察活动集中于意大利、斯堪的纳维亚半岛与俄罗斯。本研究详细还原了他于1880年夏季率领考察队前往西伯利亚鄂毕河河口期间的行程与采集成果。此次考察在植物学领域具有重要价值：共采集到562个植物分类单元，其中22个在当时被认定为科学新物种。从民族学视角来看，本次考察同样意义非凡——索米耶是首位邂逅并系统记录彼时西伯利亚各原住民群体的意大利科学家。本次考察途经的所有点位均已完成地理坐标标定，并以地形图形式呈现，清晰展示了考察路线以及对应后续被描述为科学新种的分类群标本的采集位点。
