This pretty flower looks like a lady's slipper, and therefore it is called a lady's-slipper, or moccasin flower."" With just a few more words on the plant and where it can be found, Cross describes the Jack-in-the-pulpit, bloodroot, milkweed, dutchman's-breeches, and a few more plants (twelve in all) named for ""the way they look,"" ""what they do"" (""Skunk cabbage was named for what it does. It stinks!""), or ""where they grow"" (marsh mallow). Flimsy as a botany survey--and illustrated with pleasant plant drawings but sappy ones of appreciating children--this hasn't the spark to carry off the weightless title concept.
