Types of Wheat Heads - Botanical Illustration Guide #3527387 (License: Personal Use)

This vintage line engraving displays four wheat heads arranged left to right: a compact, densely packed spike with long awns; a large, robust rachis with overlapping glumes and prominent lemma; a slender, tightly aligned spike with short awns; and an open, loosely structured head with elongated glumes and visible florets. Fine hatching emphasizes texture, seed arrangement, and bract detail, typical of scientific botanical plates from the late 1800s.
