Ib-Mac
(Van Tubergen, 1910)
The first known amphidiploid oncobred, little used in hybridizing until compatible mates came along. From I. iberica X I. macrantha. This flower is faded from exposure to New Mexico's full sun, but has the characteristic cup-shaped falls and broad, diffuse beard.
For Show aficionados, the ASI code is OB.
