Oregon grape is a species of flowering plant in the fami-ly Berberidaceae, native to western North America. It is an evergreen shrub growing to 1 m (3 ft) tall by 1.5 m (5 ft) wide, with pinnate leaves consisting of spiny leaflets, and dense clusters of yellow flowers in early spring, followed by dark bluish-black berries.

Petiole in a tree : 35-40 clustersPetiole size : 30-60 cm.

Compound leaves in a petiole : 6-10 leaves/clusterRaceme flowers in a petiole : 14-27 racemes/cluster

Leaflets in a compound leaf : 9-17 leafletsFlowers in a raceme : 60-150 flowers

Leaflets in a tree : ~500 leafletsFlowers in a tree : ~70,000 flowers

Pinnation is an arrangement of discrete structures (such as leaflets, veins, lobes, branches, or appendages) arising at multiple points along a common axis.

A raceme is an unbranched, indeterminate type of inflorescence bearing pedicellate flowers.
