hair bases being characteristic of the species well corresponds to the presumed affinity. Its diameter is 62.5 urn and the drop itself is an amorphous one without any crystalline or regular structure. Discussion: KVACEK (1979) has described the species from the European Tertiary with the remarks that subepidermal secretory bodies and hair bases are very typical of the species. Earlier the species had been described as Papilionaceophyllum liblarense by KRÄUSEL and WEYLAND (1959). The species is characteristic of the Upper Miocene and Pliocene. Among others, it has also been recorded from Pannonian and Lower Pliocene deposits of Romania and from Miocene lignits of Rhineland, Lausitz. It is possible that seeds described by MAI as Magnolia lignita represent the same species (KVACEK 1979).

Material: BP 99.502.1; BP 99.503.!. Description: Cuticle fragments of medium thickness with several stomata. The size of the isodiametric cells ranges between 20-50 um. Their arrangement is pentagonal and hexagonal. The anticlinal cell walls are weakly undulating and thickened. The randomly arranged stomata are 25-32 urn long and 20-25 urn wide. Type of stomata is paracytic, or brachyparacytic. Subsidiary cells are of similar size as epidermal cells. Length of stomatal pore is 6-10 urn. The outer stomatal ledge is considerably thickened. Discussion: Characteristic features of the species are wide stomata of paracytic type with thickened outer stomatal edge and the type of epidermal cell wall thickenings. According to KVACEK (1988) the type of stomata is in fact amphibrachyparacytic. There are several records of the species, e. g. from the Bohemian Miocene (KNOBLOCH and KVACEK 1976), from Austria (KOVAR-EDER 1982) and from Germany (MAI and WALTHER 1978). Since the shape of stomata of L. pseudoprinceps is similar to that of Ocotea Aubl. species, it is often assigned, as a possibility, to the fruits of that genus (BÛZEK et al. 1996).
