Madison Heights, flower and lichen.
Sisyrinchium rosulatum [] [voucher]
Just pressed four more plants for Andy Sanders at UCR herbarium so he could send some material to lady doing FNA and JM2 treatments. Nice samples, one with fully mature fruit finally. One plant is 3.5" tall. Some clearly show old growth, proving that they are at least occasionally biennial.
This is what I wrote up for the voucher

These were all somewhat withered; I never saw fresh material. Used key in
www.svims.ca once I settled on the genus. Photos on the web look nothing like it, but it matches the description in the key above down to (almost) the last detail.
