When a boy, in about 1844 or '45, my father received from the well-known firm, Booth & Sons of Hamburg, this Canna, under the name of Iridiflora, and if I recollect right, it was exactly the same thing sent out now as Ehemanni.

This Canna was first found by Ruiz & Pavon in Peru, and named by them Iridiflora. Curtis, in his Botanical Magazine (No. 1968), I believe in 1823, gives the first illustration of it; also Lod-diges in Botanical Cabinet (905), and Edwards in Botanical Register (609).

Prof. Reichenbach in 1826, in one of his works calls it a rare and beautiful plant, then in flower in the Botanical Gardens at Dresden (Saxony), and often confounded in European gardens with other species, but very easy to distinguish by its drooping flowers.

Mr. Heffron will see that Iridiflora is the original name given by Ruiz & Pavon, and that Ehemanni is put to it to pass an old plant for a new one. Davenport, Iowa.
