Thorn Structure Diagram - Plant Anatomy Illustration #3005976 (License: Personal Use)

This high-detail black-and-white botanical illustration depicts a woody stem with a prominent, sharp thorn emerging from a node. The drawing highlights internal vascular bundles, stipular remnants, and epidermal textures using fine linework and cross-hatching. Such diagrams are commonly used in plant taxonomy and morphology studies to differentiate thorn types (e.g., modified stems vs. spines).

Used in academic botany resources, online plant identification guides, or educational websites explaining plant defense mechanisms; targets students, researchers, and horticulturists seeking morphological clarity.
