Lithraea molleoides (syn. Lithraea molleoides var. lorentziana Lillo, Lithraea ternifolia, Schinus brasiliensis Marchand ex Cabrera, Schinus leucocarpus M., Schinus molleoides (Vell.) Engler, Lithraea aroeirinha Marchand ex Warm.[1]) is a tree (2.5 and 8 m tall) that is native to South America, specially in Argentina, Uruguay, Bolivia, and Cerrado vegetation of Brazil.

Landscaping

The plant is commonly considered as unsuitable to landscaping, as it is a poisonous plant: it produces volatile substances that propagate from touching the leaves, through contact with droplets, or through the tree's pollen. These substances are allergenic[2] and contact with them may produce general allergic sensitivity, skin disease, fever, and visual problems.[3] Planting this tree where it can be accessible to the general public is therefore strongly discouraged.

Popular custom

In Uruguay, folk tradition states that people are supposed to salute the tree by changing the time of the day. If somebody encounters the tree during the day, she is supposed to say "Good night, Mrs. Aruera". Similarly, if it is during the night, she should say "Good day, Mrs. Aruera".
