Fig. 1

Representative examples of stomatal orientation across different plant species. Panels (a–i) show stomata in (a) Lilium (Lily), (b) Taxus, (c) cuticle peel of an unspecified species, (d) Ginkgo biloba, (e) Yucca, (f) maize (Zea mays), (g) barley (Hordeum vulgare), (h) wheat (Triticum aestivum), and (i) rice (Oryza sativa). In several monocot species such as maize, barley, wheat, and rice (f–i), stomata exhibit a parallel orientation aligned with the leaf venation. In contrast, dicot and gymnosperm species like Lily, Taxus, Ginkgo, and Yucca (a–e) display more variable or random orientations. This figure demonstrates the diversity of stomatal orientation patterns across plant taxa and underscores the need for robust methods capable of quantifying orientation in diverse morphological contexts.
