Abstract

The generic name Microsisymbrium O.E. Schulz was illegitimate when described because it included the type of Guillenia Greene. The monotypic Ianhedgea is proposed to include one of the 12 species previously assigned to Microsisymbrium, i.e. M. minutiflorum (Hook.f. & Thomson) O.E. Schulz. The proper generic placement of the remaining 11 species of Microsisymbrium is presented. The following new combinations are made: Ianhedgea minutiflora (Hook.f. & Thomson) Al-Shehbaz & O'Kane, I. minutiflora subsp. brevipedicellata (Hedge) Al-Shehbaz & O'Kane, and Neotorularia quingshuiheense (Ma & Z.Y. Zhu) Al-Shehbaz, O'Kane & G. Yang.
