my two cents... I hate forma's. Forma designations are pointless nomenclatural inflation. One only need to look at Trillum recurvatum and its various forma's, color forms of various things, etc. A teratological form does not, and should not, require a name, neither do albino's, etc. If a species does exist in two color forms in disparate parts of the range then, by all means, give it a name. Iris sintensii - Italy -- if someone were to perform a phylogeographic study that shows that continental and peninsular forms were two separate clades without much divergence then a formal name would be nice. If there really is no morphological distinction, or were there no molecular differences then a cultivar name would be better. Continuing with Iris collina though is confusing when it has a proper name already. That said, is the plant Jurasek has sold seeds of the true sintenisii? I grew that plant for years, and very well, in Kansas. It was partly evergreen with floppy greyish leaves. It promptly died here in E Tennessee. Jim, do you still have divisions?

The name "Iris collina" represents an entire regional population, not just one particular clone or cultivar. If botanists (or tradesmen) choose to not accept it as a species, then it should be listed as a forma (Iris sintenisii f. collina) or a subspecies (Iris sintenisii ssp. collina) not as a cultivar. As for me, a simple hobbyist/enthusiast, I think "Iris collina" is perfectly acceptable.
