Thorned Stem Illustration - Botanical Anatomy Diagram #288158 (License: Personal Use)

This black-and-white line illustration depicts a vertical plant stem bearing two large, sharply curved thorns-one oriented upward and the other downward-each with textured surface detail suggesting lignified tissue. The drawing emphasizes anatomical accuracy, typical of 19th- to early 20th-century botanical plates used for taxonomic reference. Fine linework captures subtle ridges and attachment points where thorns emerge from the stem cortex.

Used in botanical textbooks, online plant databases, or educational articles explaining defensive adaptations in plants; matches user intent for learning about thorn morphology, plant defense mechanisms, or historical scientific illustration techniques.
