Hydrangea Leaf Anatomy - Close-Up Comparison of Upper and Lower Surfaces #2286676 (License: Personal Use)

The image displays two hydrangea (Hydrangea macrophylla) leaves positioned side by side: the left shows the adaxial (upper) surface-dark green, slightly glossy, with deeply impressed primary veins and tightly packed reticulate secondary veins; the right reveals the abaxial (lower) surface-lighter green, matte, with raised veins and subtle pubescence. Both exhibit characteristic serrated margins and acuminate tips, highlighting morphological adaptations for photosynthesis and transpiration.

Used in botanical education, horticultural guides, plant ID resources, or gardening blogs to illustrate leaf morphology; targets users seeking to differentiate hydrangea species or understand leaf anatomy for cultivation or diagnosis.
