The sickle thin-tail is a prostrate or arching ascending annual grass. The stalks are only 5–20 centimeters high. The leaves are 1–3 millimeters wide, flat or rolled up and rough on top. The ligule is 0.5–1 millimeters long. The uppermost leaf sheath is inflated. The flower spike is thin, cylindrical and curved sickle-shaped. The spikelets are single-flowered and sit individually alternately in the bulges of the ear axis. Both glumes are side by side in front of the flower, their keels are not winged.

The flowering period is April to July.

The chromosome number is 2n = 14, 24, 38 or 42.

distribution

The species occurs from Western Europe to the Mediterranean region and Pakistan and also in Macaronesia. In North and South America, New Zealand and Australia the species is a neophyte.

ecology

The species thrives in salt marshes and on ruderal sites near the coast.

Taxonomy

The sickle thin tail was first described by Carl von Linné as Aegilops incurva in Sp. Pl .: 1051 (1753). The species was described by Charles Edward Hubbard in Blumea, Suppl. 3: 14 (1946) as Parapholis incurva (L.) CEHubb. placed in the genus Parapholis newly established by himself . First, Linnaeus himself renamed the species Aegilops incurvata in the second edition of his work Species Plantarum in 1763 . Many other authors later adopted this spelling.
