The most elaborate available system of the order Jungermanniales is that of Schuster (1984). 40 families are grouped in 15 suborders. In the present paper the problem of delimitation and relationship of the higher categories (families, suborders) as well as the problem of primitive and derivate groups are discussed. A detailed analysis of the suborder Jungermanniineae is provided.
