无融合生殖的微小种的形态鉴定是困难的，需要与参考植物标本馆材料进行详细的比较。由于植物标本馆分散，即使在公共收藏中，这些关键类群的错误识别也并不罕见。在与无融合生殖多倍体属Hieracium，Pilosella，Taraxacum sect. Palustria（菊科）和Alchemilla，Pallaegus，Rosa，Rubus（蔷薇科）的分类学专家的密切合作下，我们建立了一个在线门户网站（http：//webapp.senckenberg.de/bestikri/），展示了德国植物群中每个微种的地理参考和验证的植物标本馆标本。我们的重点是分类学的可靠性，而不是纯粹的数据量，因此鉴定得到验证。此外，我们还提供宏观照片以及分类学上重要的形态特征的描述。包括目前> 400分类群，我们相信在线门户网站将大大促进研究困难的多倍体，中欧植物群的无融合生殖分类群。
Morphological identification of apomictic micro-species is difficult and requires detailed comparisons with referenced herbarium material. Access to such is limited because herbaria are scattered, and even in public collections misidentifications are not uncommon in these critical taxa. In close collaboration with taxonomic experts of the apomictic polyploid genera Hieracium, Pilosella, Taraxacum sect. Palustria (Asteraceae) and Alchemilla, Crataegus, Rosa, Rubus (Rosaceae), we established an online portal (http://webapp.senckenberg.de/bestikri/) displaying georeferenced and validated herbarium specimens for each respective micro-species of the German Flora. Our focus was on taxonomic reliability rather than on sheer data quantity and thus identifications were validated. We additionally offer macro-photographs as well as descriptions of taxonomically important morphological characters of the respective genera. Comprising currently > 400 taxa, we trust the online portal will greatly facilitate research into difficult polyploid, apomictic taxa of the Central European flora.
