Jafri, S. M. H.
The present work was taken up by me at the suggestion of Professor Sir William Wright Smith and has been done under the guidance and supervision of himself and Dr. P.H.Davis. Taxonomic studies have undergone considerable changes during the last three quarters of a century since the publication of the great Flora Orientalis of Boissier (I867) and the Flora of British India of Hooker f. (1872). Many nomenclatorial changes have been made and the taxonomic status of several species has been clarified in addition to numerous taxa added to our knowledge. Both the above mentioned Floras, therefore, need a complete revision - a fact emphasized. by several other taxonomists before Blatter, E. ( I930) ; Chakravarty, H .L. ( I948)
