Abstract(s)
Johann Reinhold Forster and his teenaged son John Georg Adam Forster (then 17) joined
James Cook’s second voyage (1772-1775), as botanist and artist, respectively. Upon their
return they described six species that are pertinent to the study of the Macaronesian flora.
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). We designate epitypes for A. rupestris and Epibaterium
pendulum J.R. Forst & G. Forst. Our study indicates that Teucrium betonicifolium Jacq. is
the accepted name for this Madeiran endemic. Lectotypes, along with epitypes, are also
designated for T. betonicifolium and T. betonicum L’Hér.
