Much of the area where Kalmiopsis grows naturally is in the Kalmiopsis Wilderness of the Siskiyou National Forest. I'm pretty sure it's the only wilderness area named for the scientific name of an endemic plant. One of my summer jobs during college was sampling vegetation in that area. It's a beautiful area but most of it burned a couple of years ago in the Biscuit fire. The Darlingtonias that grow in the bogs are also very interesting. It's a great place for finding unusual plants, you can see the Port Orford Cedar in it's very small home range and redwoods just down the coast near Brookings.
