The $p_{\rm T}$ dependence of inclusive J/$\psi$ $v_{\rm 2}$  compared with the corresponding results for prompt D mesons  and charged pions . The expected $v_{\rm 2}$ for open charm in the constituent quark approach, and for various values of the ratio $p_{\rm T}^{\rm q}/p_{\rm T}^{\rm D}$ are also shown.
