本文描述了产于江西省东部丹霞地貌区的一个新种-丹霞通脉草（Mazusdanxiacola）。基于4个质体标记（matK、rbcL、rps 16和trnL-trnF）和核核糖体ITS序列的分子系统学分析证实了该新种的系统位置，并讨论了该新种在通泉草属内的亲缘关系。在形态学上，该新种与其他Mazus物种明显不同，具有一系列不寻常的特征，即，一年生，无匍匐茎和基生叶，茎单直立不分枝，叶具长叶柄，背面灰绿色至银，叶基部截形至宽楔形，总状花序极长，可达35厘米，花冠白色，上覆有明显的棍棒状腺毛。根据IUCN红色名录分类和标准，该物种被归类为极危物种（CR）。
Mazusdanxiacola, a new species endemic to Danxia landform in east Jiangxi Province, eastern China, is described and illustrated. The systematic placement of this new species was confirmed by molecular phylogenetic analyses based on four plastid markers (matK, rbcL, rps16 and trnL-trnF) and nuclear ribosome ITS sequence, and its specific relationships within Mazus were discussed. Morphologically, the new species is clearly different from other Mazus species by having a series of uncommon traits, i.e., annual habit, without stolons and basal leaves, single, erect and unbranched stems, long petiolate leaves abaxially grayish green to silver gray, truncate to broadly cuneate leaf bases, racemes extremely elongated up to 35 cm long, white corolla, and palate densely covered by conspicuous clavate gland-like hairs. The new species is assigned to Critically Endangered (CR) according to the IUCN Red List Categories and Criteria.
