Botanical explorations were made in Chamba district of Himachal Pradesh from 1984-1988 under "BSI District Flora Project" sponsored by Botanical Survey of India. Consequently, studies on phytogeography (Singh & Sharma 1989, Sharma & Singh 1990 a), floristic composition (Sharma & Singh 1990 b), herbaceous vegetation (Sharma & Singh 1994) and biological spectnun (Sharma & Singh 1995) of the district have been published. Occurrence of Gnaphalium coarctatum Wil1d.-A South American taxon naturalized in India, has recently been reported for the first time from the district (Singh & Sharma 1988). In continuation, following 28 taxa are being reported as the new plant reports for Himachal Pradesh. These have not been included earlier in their comprehensive three volume compilation entitled 'Flora of Himachal Pradesh, Analysis' by Chowdhery & Wadhwa (1984) or by the subsequent 30 authors (see under references) who have contributed additional plant reports to this work. The arrangement of the families is as in Hooker (1872-1897). All the specimens are preserved in Herbarium, Punjabi University, Patiala (PUN).
