The genus Geranium (Geraniaceae) which contains about 400 species
recognised, is a widespread group of vascular plants, absent only in tropical
lowlands, deserts and polar regions. After Knuth’s (1912) monograph, several
regional accounts as well as some detailed studies on some sections were published,
but no comprehensive taxonomic treatment is nowadays available.
