Ecology

In a study comparing N2 fixation potential in nine legume species occurring in longleaf pine-wiregrass ecosystems, M. quadrivalvis showed clear superiority in developing a comparatively large nodule mass to support high N2 fixation activity (Cathey et al. 2010). Aboveground N concentration was also greatest for M. quadrivalis (Cathey et al. 2010). Finally, N2 fixation potential for M. quadrivalvis does not differ between shaded and unshaded environments (Cathey et al. 2010). The high potential for N2 fixation makes M. quadrivalvis a candidate species for contributing to the N economy in the restoration of longleaf pine ecosystems (Cathey et al. 2010).

Habitat

Commonly found in pine sandhill (Downer-MR_2012_MSThesis). Occurs in areas that have sandy loamy soil (Miller et al 1999).

Phenology

herbaceous climber

Seed dispersal

dispersal is by gravity (Maza-Villalobos et al 2011).
