摘要
来自中国西南部的新种鸢尾（Iris luojiensis Z.Y. Wang, H.W. Huang and R. Li sp.nov.）被描述并图解。本种分布于中国西南山区的灌木斜坡上。洛吉鸢（Iris luojiensis）在形态上与鸢尾（Iris japonica Thunb.）、鸢尾（Iris calcicola Z. C. Lu, Z.P. Huang and Yan Liu）和鸢尾（Iris wattii Baker）相似，但由于其花为蓝紫色，花茎分枝为 3-6 个，叶片大小（尤其是上部叶片）以及每个苞片只有 2-3 朵花（很少为 1 朵），因此很容易与它们区分开来。基于完整质粒基因组的系统发育分析支持将 I. luojiensis 与其他形态上相关的物种区分开来。根据形态学和分子证据，I. luojiensis 可归入 I. sect.Lophiris.
Iris luojiensis (Iridaceae), a new species from southwest China
Iris luojiensis Z.Y. Wang, H.W. Huang and R. Li 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 and Yan Liu and Iris wattii 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.
