TURKISH TOPAZ (Austin, 1962). S blue-white with amber-yellow edge; F yellow-brown with some purple striations; blue beard. Its true parentage is not known. The Court of Iris catalog listed it as being from two I. stolonifera seedlings, which would make it an R under either system by today's terminology.  At the time, however, "I. stolonifera seedling" meant that one parent was I. stolonifera, but not necessarily both.  It has not crossed with the I. stolonifera clones I've tried and its growth habits are certainly those of an RB, but its flower is so much like the yellow form of I. stolonifera that the two have apparently become mixed up in distribution.
