Briones Reservoir - July 21 2019
2019. SF Bay Area. Bay Area 2019. Along the north side of the reservior starting from the Bear Valley Trailhead. Although it's summer and mostly dry, I was surprised the how many different kinds of late wildflowers I saw.
Read MoreZeltnera muehlenbergii (Muehlenberg's centaury, native) is my best guess because I don't see much of pedicel on the flowers. Centaurium tenuiflorum (slender centuary; non-native) and Zeltnera davyi (Davy's centaury, native) are also possible. The differences live in details that are not all that clear on these photos.
