The taxonomy and nomenclature of Kalanchoe gastonis-bonnieri Raym.-Hamet & H.Perrier (Crassulaceae subfam. Kalanchooideae), with biographical notes on Gaston Eugene Marie Bonnier (1853-1922)

Abstract

The taxonomy and nomenclature of Kalanchoe gastonis-bonnieri Raym.-Hamet & H.Perrier (Crassulaceae subfam. Kalanchooideae) are reviewed. We do not recognise infraspecific taxa in K. gastonis-bonnieri. The name K. adolphi-engleri Raym.-Hamet, a synonym of K. gastonis-bonnieri, is here lectotypified. Biographical information is provided on Gaston Eugène Marie Bonnier (1853–1922), who is little known in succulent plant systematics. Bonnier, who for most of his professional career was attached to the Université de Paris-Sorbonne, France, was a leading French botanist in the late-1800s and early-1900s.
