Dear Iain, Dennis and all, I thought this topic was dead, but now that it rises again I'll add some relevant info: I collina was published (Salisbury, 1796), but is considered a synonym of Gynandriris sisyrinchium, or now Moraea sisyrinchium. No longer applies to the genus Iris. The name I collina as used by Angelo is a patronym or local name without validity (unpublished, even incorrectly) for I sintenisii. The only place this name still seems to appear is on Italian sites to point out its disjunct distribution from the main populations of this species to the north and east. Plants in cultivation under the name I sintenisii are often misidentified. The true species has stiff upright foliage to 10, 12 inches or taller. Cultivated plants may be Iris pontica a dwarf clump forming species with spreading foliage, but usually only about 4 inches in height. Add a few other dwarf spuria species and the taxonomy is in general not clear. Best Jim W. On Jan 28, 2013, at 10:58 AM, Dennis Kramb wrote: > It seems you missed the follow-up messages on PBS.
