摘　　要：报道了酢浆草科（Oxalidaceae）感应草属（Biophytum DC.）的1个中国新记录种——长梗感应草[Biophytum reinwardtii（Zucc.）Klotzsch],提供了其形态描述和标本照片,并对其后选模式作了选定。该种新发现于中国西南部中缅边境的盈江县。长梗感应草与感应草[B.sensitivum（Linn.）Candolle]最为近似,但前者的花梗在花期长5~7mm,而后者的花梗长约1mm,两者容易区别。Biophytum reinwardtii（Zucc.）Klotzsch,a newly recorded species of Oxalidaceae from China,is reported,and its lectotype is designated.An amplified description and related specimen photos are provided here.This species was newly found in Yingjiang County in the border area between southwest China and Myanmar.B.reinwardtii is similar to B.sensitivum,but differs from the latter by its pedicels 5-7mm（vs.1mm）long in flowering.
