The Amphicarpa bracteata and the very similar species, Amphicarpa comosa (L.) G. Don are two interesting cleistogenes of the legume family. The two species are similar in habitat, preferring rich woods and thickets but growing in the open, and are rather generally distributed throughout most of the state’s east of the Rocky Mountains. They have slender twining stems ranging from one to six or more feet in length that trail over the ground or use bushes, weeds, or whatever may be in their reach for a support (text figure 1). Seven species, two in America and five in Asia, are commonly listed in this genus.
