Umbellularia californica (Bay laurel) is a native California shrub / tree in the Lauraceae family, recognized by Only member of genus Umbellularia, endemic to California and southern Oregon.

Bay laurel is a California native shrub found in northwestern California, the Cascade Range foothills, Sierra Nevada, Sutter Buttes, delta region, Coast Ranges, San Francisco Bay Area, southern California, and scattered transverse and peninsular ranges in canyons, valleys, and chaparral at elevations below 1,600 meters. Flowering from November to May, this plant produces small umbel-like clusters of pale greenish-white flowers less than 5 millimeters long. Growing up to 45 meters tall with bark ranging from green to red-brown, it develops a dense, spreading form with multiple trunks. Its leaves are shiny deep yellow-green, narrowly ovate to oblong, 3 to 10 centimeters long with minute gland dots, and have a distinctive glossy appearance. The fruit is an olive-like drupe 2 to 3 centimeters long, turning dark purple when dry.

How to tell it apart

vs Laurus: Both are aromatic evergreen laurels with glossy elliptic leaves, but California bay leaves give off a powerful, peppery-camphor scent (strong enough to sting the sinuses) and are borne on nearly flat margins, while true bay laurel has a milder, sweeter aroma and distinctly wavy leaf margins.; vs Cinnamomum: Camphor tree leaves are triple-veined, with two prominent side veins arching up from near the leaf base, whereas Umbellularia leaves are simply pinnately veined with a single midrib.; vs Persea: Avocado leaves are much larger (6-25 cm) and duller, and the tree bears a large fleshy fruit, unlike California bay's smaller shiny leaves and olive-sized drupe seated in a shallow cup.; vs Prunus: Evergreen cherries like hollyleaf cherry are also shiny-leaved sclerophylls, but their leaves are often spiny-toothed and not aromatic, and their flowers are 5-petaled and borne in elongate racemes rather than small stalked umbels.; vs Morella: Wax myrtle is an aromatic evergreen shrub with narrow leaves too, but its blades are toothed and dotted with resin glands giving a sweet-resinous (not spicy-camphor) smell, and its fruit is a bumpy wax-coated nutlet.
