a. Stomate of a rose. Thread-like, reclining wax crystalloid, characteristic for many Rosaceae. b. Stomate of a lily of the valley (Convallaria majalis). The wax plates are arranged in a way that resembles the line of force pattern an electromagnetic coil generates. This wax pattern is restricted to the three monocot orders Liliales, Asparagales and Burmaniales. It is a feature of classification.
c. Stomate of the bird of paradise flower Strelitzia reginae (Musaceae). Massive, compound wax rods that form a dense waxy frill around the stomate. This 'Strelitzia-type' of epicuticular wax patterns is restricted to the monocot groups Areciflorae, Commeliniflorae and Zingiberiflorae as well as to the Bromeliales and the Velloziales and is used for their classification. d. Stomate of the common horse tail Equisetum arvense. Siliceous bodies below the cuticle stand out of the surface like knots.
e. Echeveria (Crassulaceae): Stomate at the undersurface of a leaf. The subsequent divisions leading to the generation of the stomate become apparent. The ontogeny of this stomate belongs to the 'Sedum-type'. f. Typical monocot epidermis of the grass Schizachyrium with cells arranged in rows. [W. BARTHLOTT, D. FRÖHLICH, 1983; H-D. BEHNKE, W.
