The Anacardiaceae includes primarily trees and shrubs (rarely lianas or subshrubs), with resin canals and clear to milky exudate. The leaves are estipulate, usually alternate (rarely opposite or whorled), and may be simple or pinnately compound (very rarely bi-pinnate; Spondias bipinnata). The flowers are generally not highly conspicuous but are distinctive in having an intrastaminal nectariferous disc and apotropous ovules (an ovule with a raphe that is ventral when ascending and dorsal when descending). Morphological fruit diversity is exceedingly high with a myriad of types found in the family.
