When these plants are in bloom, their flowers make identification easy.

However, when we need to identify these plants, flowers are not always there. The leaves or leaflets (groups of three) leaves can be used to identify each species.

• Black medic is the easiest to identify by its leaflet. Notice the center leaf, it has a longer stem than the other two lateral leaves.
• Yellow woodsorrel leaves are heart shaped and often times folded along the midvein.
• White clover leaflet often times has a lighter green to white splotch in the middle as depicted below. The individual leaves are toothed along the margins.

Sometimes, if we look close enough within the plant canopy we can see the seed pods, or the structures on the plant that hold the seeds.

• Black medic seeds are easy to spot. Sometimes they are green on the stem, and when they dry out the seeds turn black.
• Yellow woodsorrel seed pods are easy to see as well. They are long and slender in shape, with five sides and pointed.
• White clover seed pods are found when the flower dries out, this is when the friuting pod develops. Often times not as simple to spot, but on close inspection within the canopy, these legume pods can be found.
