Pilea victoriae V. Suresh & Sojan sp.nov. 

  Diagnosis: Pilea victoriae V.

(Table 1). 


Etymology: The species is named after Government ‘Victoria’ College, Palakkad, Kerala, India in recognition of its more than 125 years of service to the education sector of the state. 

Distribution, ecology & Biotic association: So far P. victoriae sp. nov. is collected from three different localities of two districts viz. Victoria College Campus, Malampuzha and Nemmara regions of Palakkad district and Perinthalmanna region of Malappuram district, Kerala. Good populations were observed in these areas in an altitudinal gradient 100–200 m. But each population is restricted to a particular area of the collection localities.
