Resembling, and often confused with clover, it is easily identified by its yellow flowers and leaf arrangement. Take a close look at the leaflets, you'll notice that the middle leaflet has a short stalk, while the lateral leaflets are attached close to the petiole.

It's a summer annual, spread by new seed every spring, and it favored by hot dry weather. For control, pull what you can before it flowers. Treat with a broad leaf herbicide such a 2,4 D or dicamba or triclopyr. You can overseed your lawn in the fall to get a good dense stand of turfgrass. In the spring, apply a pre-emergent lawn herbicide when the forsythia blooms, that will control the new seedlings.
