No. 207, 2 April 2000, characters observed: Perennial, herb, to 30 cm.; Leaves, alternate, some in clusters, linear, 20 mm. × 1 mm. wide, glandular-sticky, regularly spaced resin pits; Inflorescence, some flowers with strap-shaped corollas, head composed of two kinds of flowers; Receptacle, epaleate; Phyllaries, in 5 not-fully-overlapping series, graduated in size, 6-11 mm. × 1.5-2.5 mm. wide, mid phyllary vein prominent throughout length though not raised, margin fringed; Rays, 7, yellow, 22-23 mm. × 5 mm. wide, 0-2 appendages to 14 mm.; Disk flowers, ±20; Pappus of well-developed bristles on both ray and disk flowers, ± cylindric; Pistil, style 8 mm. + stigma 1.5 mm. + appendages 1.0 mm.; Fruit, dense silky hairy. This collection is determined as Ericameria linearifolia, although it does not key there, primarily because the phyllaries are definitely not equal, whereas E. linearifolia requires phyllaries that are ±equal.
