Among the more conservative species present in this unit, that were lacking elsewhere at Eagle Marsh, were Actaea pachypoda, Amphicarpaea
bracteata, Arisaema dracontium, Carex conjuncta, Dryopteris carthusiana, Galium triflorum, Lindera benzoin, and Persicaria arifolia.

Moreover, genera such as Amicia, Amphicarpaea
, Canavalia, Clitoria, Lathyrus, Lotus, Lupinus, Myrospermum, and Orbexilum were restricted to these communities.

It is intriguing that four of the six N-fixers that peak outside sunny, sandy microsites are vines (Amphicarpaea
, Apios, Lathyrus, and Vicia) occurring on somewhat siltier soils [ILLUSTRATION FOR FIGURE 7 OMITTED].
Parker (1992), for example, presents evidence for the coadaptation of alleles found in two "biotypes" of a selfing annual, Amphicarpaea
bractea, that are spatially segregated over a 100-m transect.

In a little blasting hole in an old limestone quarry he finds "two fresh chestnuts, a dozen or more pea-vine (Amphicarpaea
) seeds, as many apparently of winterberry seeds, and several fresh barberry seeds," and brings them home to scrutinize under a microscope, where by comparing the tooth scratches on a shell with a deer mouse's skull that he has, he figures out what animal stored them there.
