T44N, R06W, Sec. 34, MD. Apr. 28, 1980, G.D. Barbe 2589 (CDA); Ventura Co.: San Nicolas Island, N edge of mesa, E end of old landfill, E of Living Compound. Apparently used for erosion control on inactive landfill site. Apr. 1, 1992, S. Junak SN-789 (JEPS, SBBG): NOTES: Although sporadic occurrences are well-documented, these were all determined to be casuals and accordingly the species was not included in The Jepson Manual. This species is also commonly used for roadcut erosion control and it may be difficult to determine if a local site or population is established or recently planted. Records listed above are representative; the species can be expected in every California county. Numerous unvouchered records are on file at CDA (based on specimens submitted but not retained); observed as common on roadcut banks throughout northern California, especially so along that part of the Interstate 5 corridor. Hordeum vulgare var. trifurcatum is a hooded form, reported as a roadside weed almost as often as the typical variety, although probably due to its visible distinctiveness and not frequency. Annotations at UC by N. Jacobsen (1980) do not recognize var. trifurcatum.
Initial Editorial Comments according to Source c, in California occurring as a waif (27 Feb 2003).
Correspondence and Comments Subsequent to Initial Analysis
Correspondence 1 Treatment and author notes submitted for The Jepson Manual [Ed. 2] see Comment 1
Editorial Comments 1 Correspondence 1 indicates that for The Jepson Manual [Ed. 2] infraspecific taxa are not recognized in Hordeum vulgare L., so that Hordeum vulgare L. var. vulgare is to be treated as a synonym of Hordeum vulgare L, which is to be treated as a waif in CA.
