Bromus diandrus (Ripgut brome) on the sides, Bromus sp. in the middle, and Ehrharta erecta (Erect veldt grass) with the smaller florets top right. Ripgut and veldt grass are invasive non-natives. For the second, B. carnatus (California brome) is my best guess. Oakland, near Broadway and Keith, Feb. 21, 2014.
