Lindernia tamilnadensis (Linderniaceae) from Indo-Gangetic plains: no more endemic to the Deccan

This study documents the first record of Lindernia tamilnadensis (M.G.Prasad & Sunojkumar) in the states of Uttar Pradesh, Bihar, Jharkhand, and West Bengal. Previously, 16 species of Lindernia have been reported from different parts of India. The newly acquired specimen exhibits distinct morphological characteristics compared to previously described taxa from the Indo-Gangetic plains. A brief description, field notes, photographs, location, and distribution of the species are provided to facilitate identification.
