Name

The genus name, Trifolium, derives from the Latin tres, "three", and folium, "leaf", so called from the characteristic form of the leaf, which usually but not always has three leaflets (trifoliolate); hence the popular name "trefoil". The species name, ochroleucon, is Latin for "yellowish-white", referring to the colour of the flowers.

The plant is localised in the British Isles,with the main stronghold of the species being in East Anglia, whilst the species is also present in Lincolnshire, Merseyside and Worcestershire.[4] It is fairly widespread throughout the rest of Western and Central Europe, and it has also been recorded from Iran and North Africa.[5]
