本文闡述碎米蕨葉馬先蒿 (Pedicularis cheilanthifolia) 複合群以及其三變種－ var.
cheilanthifolia, var. purpurea (Pennell) A. Garg 與 var. albida (Pennell) Tsoong。文中提供分辨此三變種之檢索表、形態、分布、物候與生態資料。重要形態鑑別特徵支持將P.purpurea Pennell 轉移為碎米蕨葉馬先蒿之變種，因之本文乃成立一個新組合名稱。

The taxonomic complexity of Pedicularis cheilanthifolia Schrenk along with its three varieties viz. var.cheilanthifolia, var. purpurea (Pennell) A Garg and var. albida (Pennell) Tsoong is elucidated and resolved. Key to varieties,morphology, distribution, phenology and ecology is provided to differentiate the varieties. Diagnostic morphological characters supported the transfer of P. purpurea Pennell Tsoong to P. cheilanthifolia, hence the new combination is made.
