Common name: Florida sensitive-briar
Synonyms: Mimosa Floridana (Chapman) Weakley & Flores-Cruz; Leptoglottis floridana (Chapman) Small ex Britton & Rose; Mimosa quadrivalvis Linnaeus var. floridana (Chapman) Barneby; Schrankia microphylla (Dryander) J.F. MacBride var. floridana (Chapman) Isely
Mimosa quadrivalvis is an armed sprawling vine with 3-5 pinnae pairs per leaf and leaflets with evident secondary veins.
The root system of Mimosa quadrivalvis includes stem tubers which store non-structural carbohydrates (NSC) important for both resprouting following fire and persisting during long periods of fire exclusion. Diaz-Toribio and Putz (2021) recorded this species to have an NSC concentration of 80.4mg/g (ranking 57 out of 100 species studied) and water content of 73.5% (ranking 89 out of 100 species studied).
This species is a southeastern Coastal Plain endemic, ranging from Georgia to Florida.
In a study comparing N2 fixation potential in nine legume species occurring in longleaf pine-wiregrass ecosystems, M. quadrivalvis showed clear superiority in growing a large nodule mass to support the high N2 fixation activity. Aboveground N concentration was the greatest for M. quadrivalis species. N2 fixation potential for M. quadrivalvis does not differ between shaded and unshaded environments. 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.
This species has been found in open pinewoods, oak-scrub woodlands, prairies, limestone glades, deciduous forests, turkey oak-pinelands, savannas, well drained ridges, ungrazed native grasslands, arroyos, and bare chalk areas. It is commonly found in pine sandhill environments. Occurs in areas that have sandy loam, peat, gravel, and/or clay loam that is dry, loose, or moist. Mimosa quadrivalvis is predominately in native groundcover with a statistical affinity in upland pinelands of South Georgia. This species can be found growing in open to semi-shaded areas.
M. quadrivalvis has shown resistance to regrowth in reestablished woodlands that were disturbed by agriculture in South Carolina coastal plain communities, making it an indicator species for remnant woodland. It exhibited its highest density in response to disking in Southern Georgia, especially in double-disked plots. The species has shown regrowth in reestablished habitat that was disturbed by disking. It became absent in response to soil disturbance by military training in west Georgia. It has shown resistance to regrowth in reestablished pine forests that were disturbed by this activity. M. quadrivalvis decreased its occurrence and became absent in response to soil disturbance by agriculture in southwest Georgia. It has shown resistance to regrowth in reestablished pinelands that were disturbed by agricultural practices.
Associated species include Pinus palutris, Quercus laevis, Muhlenbergia, Aristida longespica, A. oligantha, Juniperus, Chamaecyparis, Sabal, Magnolia, Acer, Illicium, Salix, Asclepias curtissii, Palafoxia, Paroncyhia, Quercus myrtifolia, Q. geminata, and Serenoa repens.
Seed bank and germination
Seed coats are hard and viable seed can persist in the seed bank for at least two years.
Mimosa quadrivalvis has been observed at the Archbold Biological Station to host plasterer bees such as Colletes distinctus (family Colletidae), thread-waisted wasps such as Prionyx thomae (family Sphecidae), and sweat bees from the family Halictidae such as Agapostemon splendens, Augochlorella aurata, Augochloropsis metallica, A. sumptuosa, Lasioglossum miniatulus, L. nymphalis, and L. placidensis. Deyrup observed M. quadrivalvis being visited byAgapostemon splendens, Augochlorella aurata, Augochloropsis sumptuosa, Dialictus miniatulus, D. placidensis, and Anthidiellum perplexum.
Herbivory and toxicology
The seeds are sparingly consumed by bobwhite quail and songbirds, and the leaves are commonly consumed by gopher tortoises.
