Two new species in series (Iridaceae) from south-central China.

C.A.Wilson, and C.A.Wilson, from China are described and illustrated. Both species occur on grassy slopes in mountainous regions of south-central China. The former is known from the Daba Mountains in rocky, calcareous soils associated with shrubs or mixed conifer and hardwood forests, while the latter is known from a region of karst terrain beside rice fields or under pine woods in Guizhou Province. Molecular data resolves both species in series in a subclade that also includes , while morphologically they are similar to . These newly described species are two of four members of series that occur in south-central China.
