We consider the Ramsey numberr(Ki+m,T), whereKi+m,Tdenotes the join of the complete graph of orderlwith the empty graph of ordermandTdenotes an arbitrary tree of ordern. We obtain upper and lower bounds in the general case and the complete result in the path case,T≃Pn. Also, we obtain partial results for the Ramsey numberr(Bm,K1, n−1), whereBmdenotes them-book,K2+m.
