Anacardiaceae: All Southern California members of this family are woody shrubs with milky or resinous sap.  Flowers are small; sepals and petals are in 5's on a cup-like dish with 5 stamens and 3 styles.  They are insect-pollinated. There is sometimes a disk with nectaries surrounding the base of the ovary (Clarke). Cashews, mangoes and pistachios belong to this family.
