Catclaw brier or sensitive brier (Mimosa nuttallii)
Mimosa nuttallii is a herbaceous perennial legume in the subfamily Mimosoideae. It has a trailing semiwoody vine covered with small recurved prickles that can be painful to bare skin. The ribbed stems of this plant usually grow to 4 ft. or more and are branched. Plants rarely reach more than 1-2 ft. in height. The frond-like leaves are alternate with prickly stalks. The bipinnate leaf blades are divided into 4-9 pairs of small segments, and these are again divided into 8-15 pairs of tiny leaflets. Leaflets are elliptic, glabrous, with a prominent midrib. Like a few other species of Mimosa (such as M. pudica), the leaves fold up when touched or disturbed. It is also said that the roots of M.nuttallii give off an acrid, garlic like smell when disturbed. This may be an additional defense mechanism of the plant.
