Whitemouth dayflower (Commelina erecta, Commelinaceae)

According to Wikipedia, Linnaeus picked the genus name Commelina in honor of two renowned Dutch botanists of the Commelijn family (Jan and his nephew Caspar), using the two showy petals of Commelina communis to symbolize them. Somewhere else I read that the joke was the third small, mostly obscured petal symbolized a third, less well-known botanist of the Commelijn family.

Virginia pepperweed (Lepidium virginicum, Brassicaceae)

Native
In my north Florida hometown, boys occasionally would chew the seed pods of this plant for the novelty of the biting taste, similar to mild horseradish. Pepperweed is a member of the mustard family, which also contains radishes.

Spotted sandmat (Chamaesyce maculata, Euphorbiaceae)

One interesting thing about this common roadside weed is that within each cluster of tiny, white flowers, there is nearly always one that is pink. (I read somewhere that what looks like petals are actually specialized glands.)

On March 25, 2011, "Anonymous," in a comment to this post, correctly identified this plant as Spermacoce verticillata, a non-native weed. I had previously labeled it as Alternanthera flavescens. Thanks, Anonymous, for the correction!
