Gutierrezia californica (DC.) Torr. & A. Gray

Comments ( Inglês )

Following D. D. Keck (1960) and M. A. Lane (1985), Gutierrezia californica is treated here as a variable taxon that includes G. divergens. O. T. Solbrig (1965, 1970) considered G. californica to be a narrow endemic restricted to serpentine outcrops of the San Francisco Bay region, in which case the earliest name for the more widely distributed plants, including those of Mexico, is G. divergens Greene. Molecular evidence (Y. Suh and B. B. Simpson 1990) tentatively supports the recognition of the serpentine endemic; more detailed sampling would be needed for an objective decision. The morphologic differences are quantitative and overlapping. Intergrades between G. californica in the broad sense and G. sarothrae are said to occur in California (Lane 1993).

Gutierrezia californica ( Inglês )

fornecido por wikipedia EN

Gutierrezia californica is a North American species of flowering plant in the family Asteraceae known by the common names San Joaquin snakeweed and California matchweed. It is native to California and Arizona in the United States and Baja California in Mexico.[2][3][4] It grows in sunny sandy or rocky areas in grasslands, scrub, or open woodlands.[5]

This is a small subshrub reaching up to about half a meter (20 inches) in height. It grows clumpy or gangly and generally erect stems in shades of gray and red which are lined with small linear green leaves.[5]

At the end of each branch of the stem is an inflorescence of one to three small flower heads just a few millimeters wide. The head contains several yellow disc florets with long, protruding styles and several yellow ray florets around the edge.[5]
