Abstract.
We propose a completion of the treatment of the theory of
André trees due to D. Foata and M.-P. Schützenberger
in ["Nombres d'Euler et permutations alternantes", University
of California, Gainesville, 1971]. In particular, we show how to
recover one of the results established there with the help
of an ingenious but relatively complicated procedure of Christiane
Poupard in [Disc. Math. 38 (1982), 265-271].
