I.D’d by David Styer, our naturalist guide for the day. Per Calflora website, there are currently 47 observations of it in California, all on Fort Ord. Habitat: Maritime chaparral. Soil: Hard-packed sand, ancient sand dune, former marine terrace. Off Barloy Canyon Rd.
A.k.a Capetown grass or Cape Grass. A non-native, introduced/naturalized, perennial Tribolium (Hare Grass). Endemic to South Africa, now naturalized on Fort Ord. David speculates that seeds may have been inadvertently transported to Ford Ord from South Africa by military machinery and personnel. It is now quite widespread in this area.
