Abstract

Gunnera x cryptica J.M.H.Shaw representing the hybrid G. manicata Linden ex André × G. tinctoria (Molina) Mirb. is described from spontaneous seedlings in cultivation. It is widespread in the British Isles, and appears to have completely replaced G. manicata in cultivation. Details of the earliest publication, authorship and typification of G. manicata are provided, along with the origin and history of the hybrid, and notes on G. tinctoria including a previously overlooked synonym G. thyrsiflora Ruiz ex Barreiro.
