  植株高8-25厘米。茎直立、上升或中下部匍匐，着地部分节外也生根，下部近无毛，上部被细柔毛，常红紫色，分枝或否。叶4-6对，在茎上均匀分布或上部较密，下部的叶具长近1厘米的叶柄，上部的叶具短柄，叶片薄纸质，卵形至长卵形，长2-5厘米，宽1.2-3厘米，基部通常楔形，少钝，顶端常急尖，边缘齿尖向叶顶，两面无毛或仅上面被短柔毛或两面都有短柔毛。总状花序1-4对，侧生于茎上部叶腋，长3-6厘米，有疏生的花数朵，总梗长0.5-1.5厘米，花序轴和花梗被细柔毛；苞片条状披针形，比花梗短，无毛；花梗直，花期长1-2毫米，果期长3毫米；花萼裂片条状披针形，无毛，花期长3-4毫米，果期稍伸长；花冠白色或淡红色，具紫色条纹，直径约10毫米；雄蕊略短于花冠。蒴果折扇状菱形，长4-5毫米，宽9-11毫米，基部成大于120度的角，有的几乎平截形，上缘疏生多细胞腺质硬睫毛，花柱长2-3毫米。种子长1.5毫米。花期4-5月。
  分布于云南、贵州、四川、湖北、湖南、江西（武功山）。生海拔500-2300米的阴湿地。
  过去这个种与灰毛婆婆纳相混，但两者区别明显，本种茎下部匍匐生根且在茎叶被毛、叶形、叶缘锯齿等方面均和那个种明显不同，还未发现中间类型。和膜叶婆婆纳的关系倒是比较复杂，过去也有人把这群植物都当作膜叶婆婆纳，但根据现有材料，两者以花序长短、花梗和花柱长短、叶片质地相区别，过渡尚不明显，故保持两个种的处理，或许将来发现它就是膜叶婆婆纳的一个类型。

Veronica henryi has been confused with V. cana, but they are distinct and no intermediates have been found. The relationship between V. henryi and V. riae is not completely understood, and V. henryi may be conspecific with V. riae.
