  We characterize the Schauder and unconditional basis properties for the Haar
system in the Triebel-Lizorkin spaces $F^s_{p,q}(\Bbb R^d)$, at the endpoint
cases $s=1$, $s=d/p-d$ and $p=\infty$. Together with the earlier results in
[10], [4], this completes the picture for such properties in the
Triebel-Lizorkin scale, and complements a similar study for the Besov spaces
given in [5].
