Derivation of the botanical name:
Iris, ιριϛ, ιδοϛ, rainbow; female messenger, announcer of the gods, the Greek goddess of the rainbow.
grant-duffii, named for Sir Mountstuart Elphinstone Grant Duff (1829 - 1906), known as M. E. Grant Duff before 1887 and as Sir Mountstuart Grant Duff thereafter. Baker gives the following in Curtis's Botanical Magazine. 124: tab. 7604; 1898: "This very distinct new Iris was first collected, so far as our records show, in 1864, by Mr. B. T. Lowne on the banks of the river Kishon. Several years later it was found by Sir M. E. Grant Duff in the plain of Esdraelon, recognized as a distinct species, and introduced into cultivation".
melanosticta, μελαϛ melas, black; stictos, spotted, dotted; black-spotted.
"Irus ha-bitzot", the swamp iris, the Hebrew name derives from its habitat of marshy areas.
The genus Iris has several subgenera, and the Limniris is one of them; beardless irises, growing from rhizomes.
