A wild rye ear with awns Awns on the fruit of an Australian species of grass. In botany, an awn is either a hair- or bristle-like appendage on a larger structure, or in the case of the Asteraceae, a stiff needle-like element of the pappus.
Polyxenida differ from other millipedes in having a soft, non-calcified exoskeleton, unique tufts of bristles or setae, fewer legs (no more than 17 pairs), and an absence of copulatory appendages in males. [5] [3] Individuals are small, usually 1.5 to 4 millimeters (0.06 to 0.16 inches) long and not exceeding 7 millimeters (0.28 inches) long.
The animal lacks eyes, feeling its way with two pairs of appendages close to the mouth. Several small, bristly, paddle-like appendages provide locomotion. Aphrodita are hermaphroditic, having functional reproductive organs of both sexes, with the eggs of one individual being fertilised by the sperm of another. [5]
Little barley seeds have an awn, a sharp hair-like attachment on the grain, which was then separated from the grain and possibly parched, roasted, and boiled. The seeds are nutritious and starchy. [ 11 ] 100 grams of little barley constitutes almost 24.3 percent of carbohydrates, 22.4 percent of protein, 18 percent of calories, and 5–6 ...
The arthropod body plan consists of segments, each with a pair of appendages. Arthropods are bilaterally symmetrical and their body possesses an external skeleton. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. Some species have wings.
Hordeum murinum ssp. leporinum, known as hare barley, [6] mouse barley, [7] and barley grass. [8] This subspecies grows in tufts from 10 to 40 cm (4 to 16 in) in height, [ 8 ] [ 9 ] and its flowers are attached to branches rather than to the main axis.

The head is shaped like a capsule with appendages arising from it. Adult mouthparts include a prominent proboscis formed from maxillary galeae, and are adapted for sucking nectar. Some species do not feed as adults, and may have reduced mouthparts, while others have them modified for piercing and suck blood or fruit juices. [3]
