This plant is growing on a wooded Southern Oregon hillside (1300 ft.) with Common Yellow Monkeyflower and Narrowleaf Mule's Ear. Looks like Nothocalais troximoides but according to "Wildflowers of Southern Oregon" by John Kemper that plant only exists east of the Cascade Range. This is growing on the west side in the Rogue Valley. The plant is about 12" tall with a single flower at the end of each stem. The leaves are long and slender with little or no "waviness." Flowers measure approximately 2" in diameter. Yes, it also grows in the middle of Poison Oak!
Microseris sp (M. borealis) most likely. Better identification can be done when it goes to fruit, to see the type of the flyer.
I am sure your ID is correct. USDA and Jepson info is that it likes marshy/bog terrain. The grow site is a small open meadow between two hills and is quite damp. Definitely fits the bill. Will watch for the fruit and hopefully further confirm your identification.
