Two new species in Iris series Chinenses (Iridaceae) from south-central China
Iris dabashanensis C.A.Wilson, sp. nov. and I. probstii C.A.Wilson, sp. nov. 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 Chinenses in a subclade that also includes I. odaesanensis, while morphologically they are similar to I. henryi. These newly described species are two of four members of series Chinenses that occur in south-central China.
