glumes

If there are six glumes, the _fourth_ bears stamens and the ovary, the _fifth_ and _sixth glumes_ are empty, and in spikelets of seven glumes, the third, fourth, and the fifth glumes are flower-bearing and contain grains, and the remaining two glumes are empty.

The first two empty glumes are called glumes by all agrostologists.

The external envelopes are called glumes as already stated.

(As we have threshed it by hand, it seems that it is hard to remove all the "glumes" from the grain too.)

Very small, individual, simple flowers (florets) are grouped in inflorescences called spikelets, which are subtended by small leaf-like bracts, the glumes.

Some thresh free from glumes, while others require husking.

The kernels are small and are often enclosed in long ellipsoid husklike coverings (glumes).

The term "free threshing" is also applied to the involute glumes of some West African guinea sorghums.

10. Sorghum: Specialty Types 1996

In one short-season variety, some farmers are selecting for tough outer glumes (the papery coat or bract around the seed) and long awns (the hair-like bristle growing out from the glume) which help protect the grains from birds, a major pest of early rice.
