The world checklist of Saldinia (Lasiantheae, Rubiaceae), four lectotypifications, and notes about nomenclature and distribution

Abstract

ABSTRACT A taxonomic revision of the mostly Malagasy genus Saldinia (Rubiaceae, Rubioideae, Lasiantheae) was conducted by Bremekamp 66 years ago. However, no holotype was selected for four of his 22 species and no distribution maps of these species were presented. The objectives of this study are, therefore, a) to produce a world checklist of the species of Saldinia with information about the type specimens, b) to lectotypify four Saldinia species, and c) to provide new distribution maps of the 22 described species. A total of 966 specimens of Saldinia (including 27 types) from the P herbarium were examined together with the protologues of all recognized species. The geographic coordinates of the 22 species recognized by Bremekamp were gathered from the specimen labels. We present a world checklist of Saldinia and four lectotypifications for Saldinia axillaris, S. acuminata, S. pallida, and S. stenophylla, and provided new distribution maps for all 22 species of Saldinia. The checklist will serve as a basis for future systematic studies in Saldinia and the species distribution maps will be useful for the ongoing taxonomic revision of the genus.
