Baron de Gossard. At L'Haÿ, one finds among the Gallicas a variety called 'Baron de Gossard' by Gravereaux...In fact, this name is very mysterious: the sources of the era mention only 'Pérou de Gossard' and 'Baron de Stassart'. In any case, this variety repeats and, thus, should not be classed among Gallicas.
