  In this short note we use the presentations found in \cite{MP} and \cite{Po}
to show that the Picard modular groups ${\rm PU}(2,1,\mathcal{O}_d)$ with
$d=1,3,7$ (respectively the quaternion hyperbolic lattice ${\rm
PSp}(2,1,\mathcal{H})$ with entries in the Hurwitz integer ring $\mathcal{H}$)
are generated by complex (resp. quaternionic) reflections, and that the Picard
modular groups ${\rm PU}(2,1,\mathcal{O}_d)$ with $d=2,11$ have an index 4
subgroup generated by complex reflections.
