your other clover you mentioned could be alsike clover. it tends to be pink to reddish in color and the leaves are not marked.
oh, and something i recently read about those buttercups, they are closely related to delphinium/larkspur/monkshood and can contain a toxin that can make animals sick if ingested, and with people can cause the skin to blister if touched for too long. so you might want to remove them carefully if you have them around your yard or in a pasture for grazing animals. it seems the dried leaves and stems don't affect animals if it gets into their hay, just the fresh eaten form. http://museum.gov.ns.ca/poison/?section=species&id=111
