R. occidentale Spurlock 3003, at a property North of Iverson Road, located South of Point Arena, Mendocino County, California.
This may be the property where R. occidentale GG 4 AK (discovered by Allan Korth on a Gene German plant hunting expedition), and R. occidentale GG 5 DM (discovered by Doris Mossman on a Gene German plant hunting expedition) may be located, but so far on this property, I have not found these two.
