Mariosousa heterophylla, also called the palo blanco tree (which is also applied to Ipomoea arborescens),[3] palo liso, guinola,[4] and Willard acacia, is a normally evergreen mimosoid plant in the genus Mariosousa native to Mexico. The Spanish common name translates into 'white stick', defining its peeling white bark. A compound called willardiine, that acts as an agonist in glutamate receptors, can be isolated from M. heterophylla.[5][6]
Description
[edit]It can grow 10–20 ft or more with a spread of 1⁄3 to 2⁄3 the height. It is a very slender tree with few branches as well as leaves. The petiolar-rachis is characteristically long and functions as a cladophyll. it has a white or yellow-colored peeling off bark. The leaves have 5–6 leaflets in the end. It may drop leaves in autumn and winter. The flowers are like catkins, rod or bottle-brush-like, white or light yellow in color. The pods are multichambered, and 3–4 in long specimens.[7] The flowers occur in pale yellow spikes.[8]
Distribution and habitat
[edit]The plant is endemic to Sonora (Sonoran Desert), Mexico. It prefers rocky bajdas, slopes and arroyos from 0 to 2,000 feet elevation.[9] It is a popular ornamental tree in arid areas, especially in the southwestern U.S.[10]
