Data from: Iris luojiensis (Iridaceae), a new species from Southwest China

Iris luojiensis, sp. nov. from Southwest China is described and
illustrated. This species occurs on shrub slopes in mountainous regions of
southwest China. Iris luojiensis is morphologically similar to Iris
japonica Thunb., Iris calcicola Z.C.Lu, Z.P.Huang & Yan Liu and
Iris watii Baker, but easily distinguished from them by its bluish-violet
flowers, 3-6 flowering-stem branches, leaf size, particularly the upper
leaves, and by only having two to three (seldom one) flowers per bract. A
phylogenetic analysis based on the complete plastid genome supports the
separation of I. luojiensis from other morphologically related species.
According to morphological and molecular evidence, I. luojiensis can be
placed in the I. sect. Lophiris.
