We consider  the Brownian tree  introduced by Aldous and  the associated
Q-process  which consists  in an  infinite  spine on  which are  grafted
independent Brownian  trees. We  present a  reversal procedure  on these
trees that  consists in looking at  the tree downward from  its top: the
branching  points   becoming  leaves   and  leaves   becoming  branching
points. We  prove that the distribution  of the tree is  invariant under
this  reversal  procedure,  which  provides a  better  understanding  of
previous results from Bi and Delmas (2016).
