Sensitive Briar, Littleleaf Sensitive-briar - Mimosa microphylla


Family: Fabaceae - Pea family Genus Common Name: Mimosa Native Status: NativeDicot Perennial Vine Herb
Mimosa microphylla - Sensitive Briar, Littleleaf Sensitive-briar. Thumbnail size flower. Allan Ihrer has suggested that this might be M. nuttallii. USDA, however, does not list that species in Tennessee. I originally identified this as M. quadrivalvis, which is listed both as a synonym of M. nuttallii and M. microphylla, and subsequent investigation indicates M. microphylla is likely the correct identification.

Found in:
AL, FL, GA, IL, KS, KY, LA, MS, NC, SC, TN, TX, VA

While this is a member of the pea family, it definitely does NOT have a pea-like blossom. The thumbnail-size pink ball is a cluster of tiny flowers.

The "Sensitive Briar" name comes not only from the stickers on the stems, but from the fact that the pinnate leaves "close" when touched, as shown in this animated photo.
