Echinocereus dahliaeflorus    (April Fool's Day - 1900)

A German garden journal, Möllers Deutsche Gärtner Zeitung (15:148), printed details of a fictitious species of cactus, Echinocereus dahliaeflorus, in its April edition. The editor of the journal apparently forgot his own joke because he indexed the cactus name at the end of the year. [The Cactaceae]
