A sample of 3.95M psi (2S) decays registered in the BES detector are used t o study final states containing pairs of octet and decuplet baryons. We rep ort branching fractions for psi (2S)--> p(p) over bar, <<Lambda>(Lambda )ov er bar>, Sigma (0)<(<Sigma>)over bar>(0), Xi (-)<(<Xi>)over bar>(+) Delta ( ++)<(<Delta>)over bar>(--), Sigma (+)(1385)<(<Sigma>)over bar>(-)(1385). Xi (0)(1530)<(<Xi>)over bar>(0)(1530). and Omega (-)<(<Omega>)over bar>(+). T hese results are compared to expectations based on the SU(3)-flavor symmetr y, factorization. and perturbative QCD.
