Garryaceae

Garryaceae is a small family of plants known commonly as the silktassels. It contains two genera:
"Aucuba" was included in the family Cornaceae or Aucubaceae in some classification systems. 
Together with "Eucommia ulmoides" the Garryaceae are currently placed by the Angiosperm Phylogeny Group in an own order, the Garryales.
Chemical characteristics.
Petroselinic acid occurs as the major fatty acid in "Aucuba" and "Garrya" species, and is also found in the families Griseliniaceae, Apiaceae and Araliaceae of the Apiales. 
Distribution.
The family is found in warm temperate and subtropical regions, "Garrya" in North America, and "Aucuba" in eastern Asia. They are evergreen shrubs or small trees with opposite, simple leaves. While they are different in morphology, the two genera have similar phytochemistries and can be intergrafted.
