James Cook y la botánica macaronésica: notas nomenclaturales de las nuevas especies descritas por Johann R. Forster y J. Georg A. Forster

Johann Reinhold Forster and his teenaged son Georg Forster (then 17) joined Captain James Cook’s second voyage (1772-1775), as botanist and artist, respectively. Upon their return to Europe, many species were described by these two German naturalists based on the plants that they collected or recorded during the voyage. Here we provide a nomenclatural study of six of the species that they described and that were reported for Macaronesia. Previous typifications are revisited and we designate lectotypes for Aytonia rupestris J.R.Forst. & G.Forst. (Aytoniaceae), Borago tristis G.Forst. (Boraginaceae), and Teucrium canescens G.Forst. (Lamiaceae). Previous lectotypifications performed for Antirrhinum elegans G.Forst. (Scrophulariaceae), Epibaterium pendulum J.R.Forst. & G.Forst. (Menispermaceae), and Sida pannosa G.Forst. (Malvaceae) are confirmed but we designate epitypes for A. rupestris and E. pendulum. Our study indicates that Teucrium betonicifolium Jacq. (= T. canescens G.Forst., = T. betonicum L’Her.) is the accepted name for this Madeiran endemic. Lectotypes were also designated for T. betonicum and T. betonicifolium with an epitype also designated for the latter.
