Grass Leaf Anatomy: Awn, Palea, and Lemma Explained #182059 (License: Personal Use)

This black-and-white line diagram illustrates three critical structures in grass inflorescences: the awn-a slender, often bristle-like extension from the lemma; the palea, the inner protective bract; and the lemma, the outer bract enclosing the floret. The drawing emphasizes their spatial relationship and morphological features typical of Poaceae family members.

Used in educational botany resources, plant identification guides, or agricultural extension materials to teach grass morphology; targets students, researchers, and agronomists seeking to understand cereal or forage crop anatomy.
