Festuca brachyphylla ( Anglèis )

fornì da wikipedia EN

Festuca brachyphylla, commonly known as alpine fescue or short-leaved fescue, is a grass native to Eurasia, North America, and the Arctic. The grass is used for erosion control and revegetation. The specific epithet brachyphylla means "short-leaved". The grass has a diploid number of 28, 42, or 44. This species was first described in 1827.[2]

Description

Festuca brachyphylla is a bright green perennial grass that is tufted or loosely cespitose and erect, growing without rhizomes. The grass has slender, low growing culms measuring 2–35 cm (0.79–13.78 in) tall that can reach 55 cm (22 in) when the grass is cultivated. The culms are glabrous and somewhat scabrous, becoming more puberulent towards the inflorescence, and are occasionally tinged purple at their base. The smooth or scabrous leaf sheaths are closed for half of their length. The sheaths remain at the basal tuft when dead. The ligules measure 0.1–0.4 mm (0.0039–0.0157 in). The capillary leaf blade are long and soft, measuring 2–6 cm (0.79–2.36 in) long and 0.5–1 mm (0.020–0.039 in) wide, and arise from the basal tuft. The inflorescences are typically cylindrical or ovoid panicles that are 1–3 cm (0.39–1.18 in) long, though they can occasionally be racemes. The panicles have one to two erect branches at each node that sometimes become spreading during anthesis. The pedicellate spikelets are purplish or bronze.[3] The spikelets measure 3.5–7 mm (0.14–0.28 in), each with two to four florets. The glabrous glumes are ovate to lanceolate and are much shorter than the spikelets. The lower glumes are 1.8–3 mm (0.071–0.118 in) and the upper glumes are 2.6–4 mm (0.10–0.16 in). The elliptical or lanceolate lemmas are membranous and become scabrous towards their apex. The lemmas are 2.5–4.5 mm (0.098–0.177 in) long. The terminal awns are 1–3 mm (0.039–0.118 in) long. The paleas are 3–5.5 mm (0.12–0.22 in) long. The anthers are 0.5–1 mm (0.020–0.039 in) long.[4][5] These short anthers distinguish the species from Festuca ovina.[6]

The spikelets are colored red to purple by anthocyanin pigments.[5]

The plant flowers from late June into July.[4]

Distribution and habitat

Festuca brachyphylla is circumpolar and alpine, occurring in North America throughout Canada and along the Rocky Mountains, growing as far south as New Mexico and California.[7]

Festuca brachyphylla grows in rocky places at high altitudes, from 2,800–4,300 m (9,200–14,100 ft).[8] It occurs in wet meadows, along streams, on riverbeds, on dry gravel, and on dry slopes.[3]

Опис

Це багаторічні трав'янисті рослини, які формують маленькі, щільні купини. Стебла в Арктиці до 15 см, у Китаї — (5)8–30(55) см, прямостійні, голі, зазвичай шорсткі трохи нижче суцвіття. Пазухи листя голі. Основи стебел оточені від блідо-коричневого до жовтувато-білого кольору пазухами листя минулих років. Листя зелене або часто пурпурне. Листові пластини (1.5)2–10(20) см × 0.5–0.8 мм. Лігули дуже короткі, менше 1.0 мм.

Одиниці суцвіття Poaceae — колоски, майже завжди численні в волотях або колосовидих суцвіттях. Колоски складаються з 2-х лусок (приквітки для колоска) і одної або кількох квіток. Квітки містять леми (нижні квіткові луски) і верхні квіткові луски.

Суцвіття — колосовиді відкриті вузькі волоті, 1.5–4(5.5) см завдовжки, гілки суцвіть 0.2–1.5 см, дуже шорсткі. Колоски 4–8 мм, як правило, коричневі або коричнево-фіолетові, іноді зеленуваті, з 2–6 квітками. Колоскові луски гладкі й блискучі, краї голі, вершини гострі або тупуваті: нижня луска вузько ланцетна, (1.2)1.5–2.5(3.3) мм, верхня луска довгаста, (2.4)3–4.5 мм. Леми 3–4.5(5.2) мм, шершаві. Ості 0.8–1.5 мм, дуже шорсткі. Верхні квіткові луски шорсткі. Пиляки (0.5)0.7–1.1(1.3) мм завдовжки. Плоди — однонасінні сім'янки. 2n= 42 (6x).

Відтворення

Статеве розмноження насінням, немає вегетативного розмноження. Вітрозапильний вид. Шорсткі остюки можуть прикріпитися до птахів і тварин, а також дещо полегшити поширення під дією вітру.

Поширення

Цей панарктичний тундровий вид (Канада, Аляска, Ґренландія, Шпіцберген — Норвегія, арктична Росія), який досягає на півдні центральноазійських гір (Китай, ТарбагатайКазахстан, Киргизстан, Таджикистан, Монголія), гір Канади й США.

Населяє у горах: альпійські луки, гірські схили, ліси, чагарники, щебнисті місця; у панарктиці: галькові рівнини й верескові схили з відкритими ділянками.
