Holotype: UU-LPP prep. 755 (=Clement-Westerhof, 1987, pl. 1, fig. 1).
Shoots bearing spirally arranged bifacial leaves. Observed width of axes
up to 5 mm; axes together with leaves up to 30 mm. Leaves slightly overlapping,
straight. Different shapes and dimensions of leaves indicating heterophylly:
(1) Shape narrow-subtriangular with acute apex; observed dimensions up to 35 mm
long, 6 mm wide; leaf base rhomboid, slightly decurrent; this type of leaves
possibly originating from main axes; (2) Shape ovate, apex obtuse, observed
dimensions up to 10 mm long, 4 mm wide, margin sometimes sinuate; (3) Shape

Type species: Majonica alpina Clement-Westerhof, 1987
Conifer. Shoots bearing spirally arranged bifacial leaves. Heterophylly
may occur. Shape of bracts rhomboid with acute apex. Ovuliferous dwarf-shoots
almost freely arising in bract-axils, bilaterally symmetrical, showing two
planes of symmetry, provided with a single or several sterile scales forming median
part and two laterally emerging recurved fertile scales forming the flanks.
Fertile scales bearing, basally on their abaxial surface, an inverted ovule.
Places of ovule attachment explicitly laterally situated. Fertile and sterile
