RÉSUMÉ Une nouvelle espèce de Tricholepis (Asteraceae: Cardueae) de l’Inde. Une nouvelle espèce d’Asteraceae, Tricholepis raghavendrae Saklani & Chaudhary, de Himachal Pradesh (Inde), est décrite et illustrée. Elle diffère MOTS CLÉS des autres espèces du genre par les feuilles inférieures pétiolées et les feuilles Tricholepis, Asteraceae: Cardueae, supérieures pinnatifides, les bractées ciliées, les écailles pubérulentes, les fleu- Inde. rons pourpres et les aigrettes libres et scabres.

During the course of conducting botanical ture (HOOKER 1881; RECHINGER 1980; HAJRA field work one of us (AS) collected some interest- 1995 and CHAUDHARY & PANDEY 2001) showed ing material of Tricholepis DC. (Asteraceae: that these specimens could not be assigned to any Cardueae) near Palampur in Himachal Pradesh, existing species within the genus and therefore India. Careful analysis using the available litera- represents a new species, which we describe here.
