Characteristics

Habit: A perennial herbaceous plant, 20 to 50 cm tall. It has a thin, long stoloniferous rhizome (which can extend up to 1 m into the ground) and features slender, smooth, ascending geniculate culms (stems). Leaves: The basal leaves are reduced to a single red-purple sheath. The upper leaves have a flat, soft, and often pendulous blade, 3–8 mm wide, with a markedly ciliated margin and upper surface. The sheath is mostly pubescent and extends into a characteristic anteligule (2–3 mm) of a linear-leaf-shaped shape, positioned on the side opposite the blade; the true ligule is short, truncated, membranous, and just 0.5 mm long. Flowers: Grouped in a loose, equilateral panicle inflorescence, bearing a few spikelets (1 to 4) supported by elongated, erect-patent hairy peduncles (the lowest up to 6 cm long). The spikelets are erect, 4–7 mm long, and contain a single fertile flower and one or more sterile flowers. The lemmas of these sterile flowers are aborted and fused together to form a clubbed or pear-shaped protuberance (edible body or elaiosome) approximately 2 mm long. The glumes are persistent, subequal (4–5 mm), rounded on the back, mucronate, and tinged with brown-purple. The lemma (glumetta) of the fertile flower is glabrous, 5–7 mm long, and with an obtuse apex. Fruit: An ellipsoid-shaped caryopsis approximately 3.5 mm long. Seed dispersal is distinctly myrmecochorous: ants are attracted to the nectar-bearing protuberance of the sterile flower and, by carrying the spikelet to the anthill, disperse the seeds. Flowering: May - July.

Distribution and habitat

Chorological type: Paleotemperate. Distribution in Italy: Common and widespread throughout all regions of Italy. Habitat: Mesophilous species that prefers thermophilic forests, with a clear preference for holm oak, beech, and deciduous oak forests. It develops its large colonies on cool, loose substrates with a slightly acidic pH, covering an altitudinal range from sea level to 800 meters above sea level, reaching mountainous elevations in Sicily up to 1600 meters above sea level.

Etymology

Genus (Melica): The name most likely derives from the classical Latin milium (millet), via the late medieval forms melica or milica, likely referring to the rounded, pearl-like shape of its spikelets or fruit. An alternative hypothesis sees its origin in the Greek μέλι (apple, honey), due to the sweetish flavor of the stems of some species in this genus.

Species (uniflora): A compound epithet derived from the Latin uniflorus, -a, -um (with a single flower), explicitly referring to the structure of the spikelet which, unlike other related grasses, contains a single, fully developed, fertile flower.
