Mimosa microphylla

Can be distinguished from Mimosa quadrivalvis var. hystricina by the absence of raised reticulate veins on the undersides of the leaflets. Mimosa microphylla has leaflets that are smooth below or have a raised mid-vein. Mimosa microphylla is also armed with prickles which neither Mimosa strigillosa or Neptunia spp.

It can be grown from root cuttings and from seeds. Seeds average approximately 26,000/lb.

A deep-rooted, warm season perennial. Chemical analysis shows a high protein content and it is reported to be palatable to livestock. Its seeds have a purgative effect and are used commercially as a laxative (Philips Petroleum Company 1955). Scattered throughout north and central Louisiana and southeast Texas. Correll and Johnston (1978) consider it to be rare in the southern part of east Texas where they believe it intergrades with S. latidens. Ranges throughout the gulf coast states and north to Virginia.
