     Niebla juncosa is a divaricatic-acid species that is distinguished by its bushy growth with fimbriate branchlets, and by the sharply defined branch margins, and by the shiny cortex except for the blackened area near the base.  Two varieties are recognized by the regular and irregular direction of the branchlets; the typical variety has branchlets oriented mostly in the same direction, that of var. spinulifera has branchlets pointing in various directions.

     The type was collected on the upper surface of rocks on a ridge south of El Marrón where it was locally abundant, while other specimens have also been collected on sand under bushes near sea level as near Morro Santo Domingo (Spjut 9834).   Variety spinulifera is characteristically terricolous north of Campo Nuevo, but also occurs on rocks of ridges throughout much of Baja California Norte along the Pacific Coast.
