Abstract

The taxonomy complexity of Pedicularis cheilanthifolia Schrenk along with its three varieties viz. var. cheilanthifolia, var. purpurea (Pennell) Tsoong ex 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 (Pennel) Tsoong to P. cheilanthifolia, hence the new combination is made.
