Alien plants of Fuerteventura, Canary Islands. Plantas extranjeras de Fuerteventura, Islas Canarias - korrigierte Fassung vom 23.01.2002 - Prof. Dr. Dietmar Brandes, Dipl.-Biol. Katrin Fritzsch. Arbeitsgruppe für Vegetationsökologie und experimentelle Pflanzensoziologie Botanisches Institut und Botanischer Garten der TU Braunschweig D-38023 Braunschweig.
