I want to the Botanical Gardens this afternoon. To be honest, I really can only identify grasses if they have a sign next to them with the name and latin name. I did see Silvergrass (Miscanthus sinensis), which I learn through on-line searches that it is considered an invasive species. (a photograph of it is above) Also I found ‘Elk Blue’ blue-gray rush (Juncus patens). I've come to learn that this really isn't part of the grass family, but often appears in books on the subject as an addition.
The garden, by the way, was absolutely beautiful--is one of of San Franciscos hidden gems. Today It is overcast, as usual, in the Sunset, but it feels like a November afternoon in Chicago or New York.
