Mariosousa willardiana, also called Palo Blanco tree,[2] palo liso, guinola[3] and Willard Acacia, is a normally evergreen 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. willardiana.[4][5]

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.[6] The flowers occur in pale yellow spikes.[7]
