The genus Saxifraga is large and diverse, and so it is useful to
divide it into Sections that reflect the current understanding of the
relationships between species. Here, we follow Richard Gornall's 1987
classification, although recent DNA studies support a move to split off Sections
Micranthes and Merkianae as a separate genus Micranthes.
We hope to show and describe an increasing selection of these wonderful
plants in wild and in cultivation on these pages, and present different ways of
accessing classification systems. At present you may simply browse or
hierarchy of SaxBase, which so far holds
names of all the currently accepted botanical taxa in a searchable form.
