Abstract
A new species of Limonium from Namaqualand coast, South Africa is here described and named Limonium dagmarae. Shared morphological characters with related South African species place the new species within Limonium sect. Circinaria. Evidence is presented to segregate the new species from relatives based on discrete morphological and environmental characters. The holotype of the L. dagmarae is preserved at NBG.
Key words: Afrolimon, Limonium sect. Circinaria, species nova, strandveld, Succulent Karoo
