The pink coloured Knotted Clover is the analogue of this rarer white flowered plant which is a hairy annual, the hairs being appressed to the stem upwards. All leaves are alternate on the stem (despite the top 2 leaves usually looking as if they are opposite, but they are not). It is usually procumbent along the ground, measuring up to 20cm in length.

The leaves are in 3-s with the individual leaflets being obovate and hairier underneath. The flowers are in small crowded bunches and do not seem to open much at all.

An isolated bunch of just 7 white-petalled flowers. The flower heads (bunches) are not stalked and between 5 to 12mm long.

The flowers might have pink tinges before they are fully developed. The leaflets of the leaves on the stem have a gradually tapered point at their tips.

The flowers are 4 to 7mm long and don't seem to open wide at all.

The side-veins of the leaflets curve outwards (best seen in top 2 leaflets).

The rear flowerhead still in flower; the nearer one turning to fruit.

This seems to be as far as the petals open, with the thin but long banner folded at 45° around the longish wings and the smaller keel hiding well.

Just turning to fruit; the petals withering to a fawn-brown.

The five sepal teeth look about equal in length. [The two upwardly-curved brown cup-shaped objects on the middle left are old leaves - look at the outwardly-curved veins]

In fruit the racemes are spherical to ovoidal (between 1.5x to twice as long as they are wide). [The curled up dark-brown but hairy 'tails' are the old leaves]

When in fruit the sepal teeth splay outwards.

Two specimens hung out to dry. The upper leaves are longer than the lower leaves. [Smallest squares: 1 mm]


Easily mistaken for : Knotted Clover (Trifolium striatum) which is also both hairy and procumbent but at up to 30cm could be longer than Rough Clover at up to 20cm. It has flowers 4-7mm long too but they are pink (not white to palish pink)

Not to be semantically confused with : Rough Chervil (Chaerophyllum temulum), Rough Stonewort (Chara aspera), Rough Hawk's-beard (Crepis biennis), Rough Horsetail (Equisetum hyemale), Rough Hawkbit (Leontodon hispidus), Rough Poppy (Papaver hybridum), Rough Comfrey (Symphytum asperum) or Rough Cockelbur (anthium strumarium) [all plants with similar names]
