Locoweed (4)

The Pea (Fabaceae) family is very large and individual species are often identified by their seed pod rather than their flower. Common names include Milkvetch and Locoweed. The lower petal, the "keel", of the Milkvetch is rounded while the Locoweed is pointed. These are a few of the many.
