Allium is a genus of about 700 botanical species distributed all over the extra-tropical part of the northern hemisphere.

Many results have already been published. Because it was often impossible to characterize every single taxon botanically in detail for which results were presented in these publications, the IPK Allium Database presents images of Allium taxa dealt with in our publications but not shown anywhere else. Also already published results and images of herbarium specimens are included as graphic files. Addition of more species and results is under work. ... [Information of the supplier]
