Or it can be a erect plant to 15cm. It grows in low or short-cut grass, lawns especially. The leaves are smaller than those on Lesser Trefoil which looks similar.

The length of the leaflet stalks are equal for each triplet leaf. The flowers, at 2-3mm long each, are also smaller than those on Lesser Trefoil (which are 3-4mm long). The flowers are also on longer stalks and with fewer flowers in a bunch (between 2 to 6) [but can be as low as just one or as many as 10] and on a longer-stalked head.

Easily mistaken for : Lesser Trefoil (Trifolium dubium) which also has small yellow flowers. See captions for differences.

The fruits (not yet shown) are between 1.5 to 3mm across and contain either 1 or 2 seeds.

It grows on short turf such as close-cut lawns and is present throughout most of Britain but rare in Ireland and Scotland (wherein it is not native). Like all trefoils the flowers are yellow in colour.
