(hexaploid, 2n = 66). Three interspecific hybrids are expected and two are known to be present: I. Xpseudotruncata D.M. Britton \& D.F. Brunton (triploid, 2n = 33) and I. Xtruncata (Eaton) Clute (pentaploid, 2n = 55). The missing hybrid taxon is I. echinospora (diploid)I. occidentalis (hexaploid).},
