Trifolium resupinatum

Τριφύλλι το οπισθοκλινές

Etymology of Trifolium resupinatum: The name of the genus, "Trifolium" derives from the Ancient Greek "τρία" [tria], meaning "three" and the Latin "folium", which means "leaf", hence "three-leafed", referring to the three leaflets that comprise a leaf. This word is a calque of the Ancient Greek "τρίφυλλο" [trifyllo], which actually means the same thing. The epithet "resupinatum" derives from Latin and means "the one bending backwards" in reference to the twisted corollas bending backwards.

Around 35 Trifolium taxa have been identified in the wild Cypriot habitat so far.

Trifolium resupinatum, even though it is encountered in many regions of Cyprus at an altitude of up to 1400 metres, it is a rather uncommon plant to see. It does not grow in the vast Mesaoria region (from the northwestern to southeastern plains of Cyprus). Its flowering period is between March and July.

How to identify Trifolium resupinatum:

Trifolium tomentosum is similar to resupinatum. Generally, tomentosum is more commoner than resupinatum and their main difference is the size of the flower head, which is double of resupinatum. Another two main differences are the appearance of the flower head, which for tomentosum is hemispheroid to spherical, for resupinatum is rather flatter, and the peduncles are shorter for tomentosum compared to the ones of resupinatum. In more detail:

Tomentosum's calyx throat has a ring of hairs. The fruiting heads are mostly 5–11 mm in diameter, hemispheroid to spherical in fruit, subsessile or borne on a peduncle shorter than 20 mm, shorter than subtending leaves, and the stems are 5–15 cm tall.

Resupinatum's calyx throat is glabrous. The fruiting heads are mostly 10–20 mm in diameter, lobulate in fruit, borne on elongate peduncles 20–50 mm long, longer than subtending leaves, and its stems are mostly 10–40 cm tall.
