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.
