Résumé

Alors que la notion de Préspermatophytes est discutée, parfois contestée, divers arguments d'ordre biochimique, morphologique, anatomique et physiologique (reproduction) conduisent à confirmer la validité du taxon des Préspermatophytes. Taxon distinct qui, du point de vue biosystématique, se situe entre les Ptéridophytes et les Spermatophytes Gymnospermes.
