A small glume or a diminutive structure similar to a glume, particularly the inner bracts of grass flowers.
From Latin 'gluma' (husk) + '-ella' (diminutive suffix meaning 'small'). This botanical term was coined in the 19th century to distinguish smaller scale-like bracts from the main glumes.
Glumellas show how plants use nested layers of protection—it's like Russian nesting dolls, with each leaf-scale perfectly positioned to shelter the delicate flower inside.
