Due to the lack of complete taxonomic inventories and revisions for nearly 120 years and a high number of chaotic and conflicting species descriptions in the times of the primary biodiversity exploration, the actual diversity of apomictic species of in Finland is currently unknown. The existing nomenclatural and bibliographic inventory, published in 2002, does not include taxonomic evaluations. To compensate for this deficiency, there is an urgent need for a new taxonomic revision. The operative foundation for this revision is an inventory of the taxonomic diversity and distribution patterns on the basis of primary sources, i.e. herbarium collections identified by major taxonomic authorities.
A complete checklist of species occurring in Finland, which were accepted in major authoritative sources (recently or in the past) and identified in herbarium collections, includes 137 accepted species, which are deemed mostly apomictic. These taxa are considered taxonomically evaluated and are recommended for current use in national checklists and manuals. Brief species descriptions are provided as the basis for a new identification key. Species distributions in Finland are recorded on the basis of herbarium specimens according to the traditional biogeographic provinces of Eastern Fennoscandia. The distribution patterns revealed in the hierarchical cluster analysis highlight a largely isolated position of the Åland Islands, with strong phytogeographical connections to Sweden; the presence of taxa with strictly oceanic distributions in south-western Finland; and a high level of taxonomic dissimilarity between the north (Lapland and neighbouring territories) and the east (southern and central mainland Finland and neighbouring territories) of Finland. The eastern floristic element is considered autochthonously developed in Finland during the postglacial colonisation of Northern Europe by plants and contains numerous endemics or near-endemics of the country. Two species are established aliens, which were introduced as park ornamentals over 100 years ago. A new synonymy is established: Hieraciumschmidtiisubsp.residuum is reduced to a synonym of ; its only record in Finland is a local relic of the postglacial period, remotely isolated from the main populations in Norway and southern Sweden. Numerous further province-level and country-level records are expected in Finland in the course of a new taxonomic revision, with a total to reach or exceed 200 species.
由于近120年来缺乏完整的分类学编目和修订，且在生物多样性初步探索时期存在大量混乱和相互矛盾的物种描述，芬兰无融合生殖物种的实际多样性目前尚不清楚。2002年出版的现有命名和文献编目不包括分类学评估。为弥补这一不足，迫切需要进行新的分类学修订。此次修订的操作基础是根据原始资料编制的分类学多样性和分布模式清单，即由主要分类学权威鉴定的植物标本馆馆藏。
一份芬兰境内物种的完整清单，这些物种在主要权威资料（近期或过去）中被认可，并在植物标本馆馆藏中得到鉴定，其中包括137个被认可的物种，大多被认为是无融合生殖的。这些分类群被视为经过分类学评估，建议在国家清单和手册中当前使用。提供了简要的物种描述作为新鉴定检索表的基础。根据东芬诺斯坎迪亚传统生物地理省份，基于植物标本馆标本记录了芬兰的物种分布。层次聚类分析揭示的分布模式突出了奥兰群岛在很大程度上的孤立地位，与瑞典有很强的植物地理学联系；芬兰西南部存在具有严格海洋分布的分类群；以及芬兰北部（拉普兰及周边地区）和东部（芬兰大陆南部和中部及周边地区）之间的高度分类学差异。东部植物区系元素被认为是在北欧植物在芬兰冰后期殖民化过程中在当地发展起来的，包含该国众多的特有种或近特有种。有两个物种是外来引入种，100多年前作为公园观赏植物引入。建立了一个新的同物异名：Hieracium schmidtii subsp. residuum被归为Hieracium的同物异名；其在芬兰的唯一记录是冰后期的一个当地遗迹，与挪威和瑞典南部的主要种群相距甚远。在新的分类学修订过程中，预计芬兰还会有许多进一步的省级和国家级记录，总数将达到或超过200种。
