Three unripe ears (of barley, wheat, and rye): each has many awns (bristles) An ear is the grain-bearing tip part of the stem of a cereal plant, such as wheat or maize (corn). [1] It can also refer to "a prominent lobe in some leaves." [2] The ear is a spike, consisting of a central stem on which tightly packed rows of flowers grow.
Depending on the species, such awns have various seed-dispersal functions, either dispersing the seed by flinging it out (seed ejection); flinging away the entire carpel so that it snaps off (carpel projection); [2] entangling the awn or bristles on passing animals ; or possibly burying the seed by twisting as it lies on soft soil.

Pappus bristles are sometimes attached to a ring called an annulus or disk at the top of the achene beak. In some pollen grains, the exine around the apertures is either thicker or thinner. In pores, this border is termed an annulus. Certain flowers have ring-like constrictions at the mouth of the flower, e.g. in Huernia and Aristolochia. 2.
The bristle brush and the scrub brush are common household cleaning tools, often used to remove dirt or grease from pots and pans. Bristles are also used on brushes other than for cleaning, notably paintbrushes. Bristles are distinguished as flagged (split, bushy ends) or unflagged; these are also known as flocked or unflocked bristles. [1]
Like emmer, durum wheat is awned (with bristles). It is the predominant wheat that grows in the Middle East. Durum in Latin means 'hard', and the species is the hardest of all wheats. This refers to the resistance of the grain to milling, in particular of the starchy endosperm, causing dough made from its flour to be weak or "soft".
Farro is an ancient grain that has a lovely, soft and chewy texture, Hadley says. One cup cooked farro contains 6.5 grams of protein and six grams of fiber, as well as B-vitamins, red blood cell ...
Lemma is a phytomorphological term referring to a part of the spikelet. It is the lowermost of two chaff-like bracts enclosing the grass floret.The lemma often bears a long bristle called an awn, and may be similar in form to the glumes, which are chaffy bracts at the base of each spikelet.
caption=Setaria distantiflora (A.Rich.) Pilg., herbarium sheet. Setaria is a widespread genus of plants in the grass family. [5] [6] The name is derived from the Latin word seta, meaning "bristle" or "hair", which refers to the bristly spikelets.
