(SPEC) Iris pskemensis Ruksans

2007, Ruksans

Iris pskemensis Ruksans, (Janis Ruksans, 2007, Central Asia, Uzbekistan) Subgenus Hermodactyloides in Buried Treasures: 363 (2007). Janis Ruksans on the Scottish Rock Garden Forum notes "I. kolpakowskiana is foothill plant, pskemense from high altitudes ~3000 m. In this aspect it is close to winkleriana, but corm tunics are of kolpakowskiana type. Bulb color in kolpakowskiana usually yellow, in pskemense and winkleri whitish. Kolpakowskiana usually forms a lot of grains, pskemense very few or none, as winkleri it rarely split. Fall in winkleri and kolpakowskiana (in both subspecies) is purple without rim, in pskemense rimmed white. Standards are of different shape, too." Janis
