In botany, lacking stipules (small leaf-like appendages at the base of a leaf stem).
From Latin 'e-' (without) + 'stipula' (stipule, a small stalk or blade). The prefix 'e-' or 'ex-' means 'out' or 'without,' making this the botanical opposite of 'stipulate.'
Botanists use this technical term to describe leaves without stipules, which helps them classify and identify plant species—it's a tiny detail that matters enormously when you're trying to figure out what plant you're looking at.
