本文描述了采自中国西南喀斯特地区的金唇羊耳蒜（Liparis aureolabella）、蒙自羊耳蒜（L.mengziensis）和云南山地羊耳蒜（L.bingzhongluoensis）两个新种。黄唇忍冬容易与其近缘种区分，其叶背面紫色，正面紫色网状脉突出，唇基部耳形，花粉囊镰刀形披针形。蒙自羊耳蒜与蒙自羊耳蒜L. petiolata和L. auriculata，但与它们不同的是叶卵形至宽卵形，紫色唇，先端沿沿着边缘合生。丙中洛羊耳蒜（Liparis bingzhongluensis）与南岭羊耳蒜（Liparis nanlingensis）相似，但新种的特征是唇盘上有两条透明脊，基部胼胝体纵向凹陷，柱翅三角形。基于核糖体ITS和质体matK序列的系统发育分析表明，黄唇百合和蒙自百合与柄百合和耳状百合嵌套在一个单系分支中。l.bingzhongluensis是由l.nanlingensis、l.bingzhongluensis和l.nanlingensis组成的一个分支的姐妹。齐湖sasakii和L. krameri。此外，形态学上的比较有力地支持了这三个种是科学上的新分离种.
Liparis aureolabella and L. mengziensis, two new species from the karst region of southwestern China, and L. bingzhongluoensis, a new species from montane region in Yunnan, are described and illustrated. L. aureolabella is easily distinguished from its relatives by having abaxially purple leave with purple reticulate veins prominent adaxially, a lip auriculate at base, and falcate-lanceolate pollinia. Liparis mengziensis is closely related to L. petiolata and L. auriculata, but differs from them by having an ovate to broadly ovate leaf, purple lip and apex connate along the margins. Liparis bingzhongluoensis is similar to Liparis nanlingensis, but the new species is characterized by having a lip with two transparent ridges on its disc, longitudinally concave basal callus and triangular column wings. Phylogenetic analyses based on nuclear ribosomal ITS and plastid matK sequences showed that L. aureolabella and L. mengziensis are nested with L. petiolata or L. auriculata in a monophyletic clade. L. bingzhongluoensis is sister to a clade formed by L. nanlingensis, L. tsii, L. sasakii and L. krameri. Moreover, morphological comparisons strongly support that the three species as separated species newly to science.
