California Bay Laurel

Description:

Umbellularia californica is a large hardwood tree native to coastal forests of California and slightly extended into the state of Oregon. It is endemic to the California Floristic Province. It is the sole species in the genus Umbellularia. In Oregon, this tree is known as Oregon Myrtle, while in California it is called California Bay Laurel, which may be shortened to California bay or California laurel. It has also been called pepperwood, spicebush, cinnamon bush, peppernut tree, headache tree, mountain laurel, and Balm of Heaven. The leaves, when rubbed, have a strong aromatic smell.

Notes:

The berries were lying under the tree, I presumed they were from this tree. This was a very large tree, much larger than the other ones I saw along the creek, so I didn't recognise it as a Bay Laurel.
