  We characterize dendrites $D$ such that a continuous selfmap of $D$ is
generically chaotic (in the sense of Lasota) if and only if it is generically
$\varepsilon$-chaotic for some $\varepsilon>0$. In other words, we characterize
dendrites on which generic chaos of a continuous map can be described in terms
of the behaviour of subdendrites with nonempty interiors under iterates of the
map. A dendrite $D$ belongs to this class if and only if it is completely
regular, with all points of finite order (that is, if and only if $D$ contains
neither a copy of the Riemann dendrite nor a copy of the $\omega$-star).
