Basic types of the rugulosity patterns, the distribution of which on the flower parts shows a general pattern, can be derived from general views (1:1500) of the rugulosity of the cuticle. Detailed analysis of the rugulosity pattern at higher magnification (1:5000) reveals the diverse but also micromorphological expression of rugulosity that can be referred to types. As a transition between the rugulose and smooth parts of the cuticle blossoms, waves of varying amplitude and length appear as structural elements. They are partly disclosed even in the non-shadowed electron image of the cuticle. They are shown especially clearly, however, in metal-shadowed, non-treated preparations of the cuticle. The latter method of preparation is significant especially in the types of rugulosity which include non-rugulose areas. In types with denser rugulosity shadowing heightens the plastic effect, yet a further improvement in micromorphological details is not to be expected. By shadowing preparations of cuticle, a groove often becomes visible along the cell boundary which usually is observed in smooth areas but may occur also in rugulose areas adjacent to cell borders and is generally not evident in non-shadowed preparations.
