Covered with or having small spines or spine-like projections.
From Latin 'echinulatus,' diminutive form of 'echinatus' (spiny), from Greek 'echinos' (hedgehog, spiny), indicating a small or less prominent version of spines.
The term echinulate is crucial in biology—scientists use it to describe the intricate spiky textures of pollen, fungal spores, and even ancient fossils, helping them identify species under microscopes!
