Hopefully somebody in this newsgroup can identify these small yellow flowers (five small leaves) that have suddenly appeared in my grass -- they are everywhere. Any idea what type of weed and how to get rid of them?
Your help is appreciated. Thanks.

Have a look at Oxalis stricta (Yellow Woodsorrel):
If the flowers have four petals and the leaves are divided into five angular leaflets with toothed edges, it's cinquefoil (French for "five leaf"). The technical name is Potentilla tabernaemontanii (also known as P. verna). It's depicted in color on the cover of the 1979 edition of Sunset's "New Western Garden Book".
If this is the correct identificatiion, hand pulling will require a paring knife (also required if instead it's oxalis). In either case, a broadleaf herbicide will also be effective on a grass lawn.
