Poison-oak, Toxicodendron diversilobum,  a shrub of the Sumac family, Anacardiaceae

by Doreen Smith

If you are you looking for bright Fall color in our wildlands the poison-oak is magnificently clothed in red at this time of year. Of course the whole shrub is still very allergenic, no-one who has any sense ever gathers the leaves for decorations. The berries make nutritious snacks for birds: the fruits are relatives of the mango, pistachio and cashew nuts.
