Details of cuticle prepared from the seed of ginkgophyte leaf with putatively attached seeds. a: Cuticle prepared from the seed of the specimen with several stomatal complexes and idioblasts. Scale bar 100 μm. b: Seed cuticle with stomatal complexes in detail; the lower one shows also the guard-cells. In the upper part of the picture two idioblasts are shown in detail. Scale bar 100 μm. c: Inner side of the seed cuticle (SEM). Scale bar 100 μm. d: Detail of figure 8 c showing an idioblast (SEM). Scale bar 50 μm. e: Detail of figure 8 c showing one stomatal complex. Scale bar 50 μm. f: Outside of the cuticle with two tubes (arrows) and at least one stomatal complex with very weakly developed papillae. Scale bar 100 μm.
