Trees or shrubs, each has inconspicuous flowers and [[resin]]ous or milky [[Plant sap|sap]] that may be highly [[poison]]ous, as in [[Metopium brownei|black poisonwood]] and sometimes foul-smelling.<ref name="pages 125-127">[[#NSB|Natural System of Botany (1831)]], [https://books.google.com/books?id=Q2QaAAAAYAAJ pages 125-127]</ref>
[[Resin canal]]s located in the inner fibrous [[Bark (botany)|bark]] of the [[Vascular tissue|fibrovascular]] system found in the plant's stems, roots, and leaves are characteristic of all members of this family; resin canals located in the [[pith]] are characteristic of many of the cashew family species and several species have them located in the primary cortex or the regular bark.  [[Tannin#Occurrence|Tannin sacs]] are also widespread among the family.<ref name="page 244-248">[[#SAD|Systematic Anatomy, (1908)]], [https://books.google.com/books?id=VagUAAAAYAAJ&pg=PA244 page 244-248]</ref>

The wood of the Anacardiaceae has the frequent occurrence of simple small holes in the vessels, occasionally in some species side by side with scalariform holes (in ''[[Campnosperma]]'', ''[[Micronychia (plant)|Micronychia]]'', and ''[[Heeria argentea]]'' (''Anaphrenium argenteum'').  The simple pits are located along the [[Vessel element|vessel wall]] and in contact with the [[Ground parenchyma|parenchyma]].<ref name="page 244-248" />

Leaves are [[deciduous]] or [[evergreen]], usually alternate (rarely opposite),<ref name="page 25">[[#IFNUS|Northern United States (1897)]], [https://books.google.com/books?id=6_IKAAAAIAAJ&pg=PA385 page 25] {{Webarchive|url=https://web.archive.org/web/20170221010018/https://books.google.com/books?id=6_IKAAAAIAAJ&pg=PA385 |date=21 February 2017 }}</ref> estipulate (without [[stipule]]) and imparipinnate (rarely paripinnate or bipinnate), usually with opposite leaflets (rarely alternate), while others are trifoliolate or simple or unifoliolate (very rarely simple leaves are palmate). Leaf architecture is very diverse. Primary [[venation (botany)|venation]] is pinnate (rarely palmate). Secondary venation is eucamptodromous, brochidodromous, craspedodromous or cladodromous (rarely reticulodromous) Cladodromous venation, if present is considered diagnostic for Anacardiaceae.<ref name="pages 125-127" />{{sfn|Pell et al|2011}}

Flowers grow at the end of a branch or stem or at an angle from where the leaf joins the stem and have [[bract]]s.<ref name="pages 125-127" />
Often with this family, bisexual and male flowers occur on some plants, and bisexual and female flowers are on others, or flowers have both [[stamen]]s and [[Gynoecium|pistil]]s (perfect).  A [[Calyx (botany)|calyx]] with three to seven cleft [[sepal]]s and the same number of petals, occasionally no petals, overlap each other in the bud.  Stamens are twice as many or equal to the number of petals, inserted at the base of the<ref name="page 25" /> fleshy ring or cup-shaped disk, and inserted below the pistil(s).<ref name="pages 125-127" />
Stamen stalks are separate, and anthers are able to move.<ref name="page 25" />
Flowers have the [[ovary (plants)|ovary]] free, but the petals and stamen are borne on the calyx.<ref name="pages 125-127" />
In the stamenate flowers, ovaries are single-celled.  In the pistillate flowers, ovaries are single or sometimes quadri- or quinticelled.  One to three styles and one ovule occur in each cavity.<ref name="page 25" />

Fruits rarely open at maturity<ref name="pages 125-127" />
and are most often [[drupe]]s.<ref name="page 25" />

[[Seed#Seed structure|Seed coats]] are very thin or are crust-like. Little or no [[endosperm]] is present.   [[Cotyledon]]s are fleshy.<ref name="page 25" />
Seeds are solitary with no albumen around the [[Embryo#Embryos of plants and animals|embryo]].<ref name="pages 125-127" />
