■ (SPEC) Iris bornmülleri Leicht. (synonym of I. danfordiae but possibly a distinct variation)
, 1891); Haussknecht separated this as a distinct species from danfordiae because it possesses a netted tunic around the bulb and he was unaware that Baker in error, had left off this character from his original description of I. danfordiae. On the specimen he received and based his original description, the tunics had been removed.
Nonetheless the plants in cultivation may have had some other distinct characteristics. In The Gardeners' Chronicle,
p.306, March 7, 1891; "Mr. Max Leichtlin, Baden-Baden, desires to make the following correction. "In consequence of an error, I sent out last year a small yellow-flowered, bulbous Iris as I. Bormmülleri.
Since then, the plant has been verified as I. danfordiae
, whilst the plant now in flower here under the name, proves to be a distinct species. The principal difference is in the size and breadth of the outer segments and of the stigma. The stigma of danfordiae is always smaller than the lamina, and is devoid of any marking. In I. Bornmülleri
, it is always larger, and has two broad stripes of bright green along its ridge; in consequence, I. Bornmülleri
looks fuller and larger." Foster disagreed with this assessment and concluded this was simply a variation of I. danfordiae
. We have noted this in the checklist to call attention to the fact that wild populations of Iris danfordiae
may show variation and we should not be mislead by the fact that all commercial sources are presently offering a single, triploid, sterile clone. Iris danfordiae
