毛脈對葉蘭(máo mài duì yè lán,學名:Neottia longicaulis (King & Pantl.) Szlach.)是蘭科對葉蘭屬植物。植株高12-14厘米。莖纖細,中部或中部以上3/5處具2枚對生葉。分布於西藏南部(吉隆)和錫金。生長於海拔2800米的喬松林下。該種唇瓣脈上疏生乳突狀短柔毛,是該屬國產種類中獨一無二的。 [1]

P. Ormerod (pers. comm.) notes that a comparison of type material of this species and Listera yueana (here treated as a synomyn of Neottia pinetorum) led him to find them conspecific, and he believes what is called N. longicaulis here and L. longicaulis in FRPS is in fact a different species (see Ormerod, Taiwania 48: 91. 2003).
