Wide-leaved rock
goldenbush, also known as cliff goldenbush, is a much-branched, spreading,
glabrous and gland-dotted shrub growing to 3' tall and having a fragrance
similar to balsam. It prefers rocky clefts and crevices on granitic
slopes and cliffs, and often appears to be growing directly out of the
rock. The leaves are crowded, ± obovate, entire or with
wavy margins, somewhat thick, and have tips that are widely obtuse or
notched. The flowering heads are generally discoid in very small
compact cymose clusters. The involucres are obconic, about 1/4"
high, and the lanceolate to obovate, sometimes resinous phyllaries are
imbricated in 4-6 series. Ray flowers are usually absent, and there
are 7-15 yellow disk flowers per head. The fruit is a 5-ribbed achene
about 1/8" long, densely-appressed silky-hairy with a pappus of
sparse brown capillary bristles. This species of goldenbush was
formerly known as Haplopappus cuneatus, but the Jepson Manual
places it in the genus Ericameria. It grows within an
altitudinal range of 4500' and 7500' and is found in pinyon-juniper
woodland and yellow pine forest in the Tehachapis and the mountains
bordering the Mojave Desert. It blooms from September to November.
These pictures were taken in Joshua Tree National Park and in
the East Mojave.
