A glume protected the tiny developing florets until the seed was fully formed.

Under the microscope, the glumes showed distinct hair-like projections that helped identify the grass species.

The field guide described the rare grass as glumed, noting a single prominent bract at the base of each floret.

The botanist noted the glumelike scales at the base of the spikelet during the field survey.

Under the microscope, the botanist counted several tiny glumellas tucked beneath each floret.

The botanist carefully separated the glumelles from the spikelet to examine their microscopic hairs.

During the dissection, the botanist carefully examined the tiny glumella attached to the grass spikelet.

Under the microscope, she noted that each glumelle bore a distinct pattern of hairs and pits.
