FLOWERS: The composite heads each enclose several yellow
disc florets. Three to five series of bracts subtend the florets. Flowering begins after the summer rains and well into autumn.
LEAVES: The leaves are linear with varying amount of pubescence between
plants and populations of plants.
SHRUB: Woody branches rise to 1+ meter in height and lack the thick coating of whitish pubescence found in similar species.
RANGE: Several similar species of rabbitbrush are distributed through
northern Arizona in the drier sites of ponderosa woodland as well as even drier
habitats such as piñon-juniper, Mojave Desert and the Painted
Desert.
UNARMED. No spines.
