Flower Not So Extinct As Before

It's a flower that has not been seen for 70 years, and I wasn't even looking for it.  Michael Park, UC Berkeley graduate student was, though, and found the flower still living on Mt. Diablo, the Mt Diablo buckwheat, Eriogonum truncatum, which had been thought to have been driven extinct from the environment by non-indigenous invasive grasses. Ertter, the curator of western North American flora at UC Berkeley's Jepson Herbarium and co-author of the 2002 revision of Mary Bowerman's "The Flowering Plants and Ferns of Mount Diablo, California," noted that one priority should be to gather seeds and start cultivating the buckwheat at the UC Botanical Garden. Cultivated specimens conserved by the garden, which is part of the Center for Plant Conservation network, will provide a reserve of seeds in case the species declines further. More detail here.
