            Figure 4. Cathaya argyrophylla, morphology and anatomy of pollen-cones; A: Ripe cones are erect; B: Detail of the cone
            base with several persisting bud scales; C & D: Detail of a single microsporangiophore; C: Microsporangiophor with a
            stalk, an adaxial phylloid rest and two microsporangia; D: Microtom cross-section of C; E: Typical microsporangiophore
            with two sporangia (MS) and a green phylloid rest with a violet tip and serrate margin (PR); F: Some microsporangiopho-
            res develop rarely three sporangia.
