Peucephyllum schottii

Peucephyllum schottii photo © by Michael Plagens

Photographed in the Muggins Mountains Wilderness, Yuma Co., Arizona. 31 Jan. 2010.

SHRUB: Medium-sized shrub mostly about one meter to two meters tall but sometimes reaching almost 3 meters. In California deserts this plant may grow as a small tree with a single trunk.

LEAVES: Dark green, linear leaves are nearly round in cross-section and so appear to be coniferous needles. With magnification the foliage is beset with small oil glands. The name Peucephyllum is derived from Greek meaning Fir-Leaf.

FLOWERS: Yellow flowers in discoid heads, i.e. there are no rays. One to two dozen florets surrounded by a dozen plus narrow phyllaries.

RANGE: Occasional in the far western protions of the Sonoran Desert from Mojave County south to Yuma County in Arizona. More common in the Mojave Desert and ranging south into Baja California Sonoran Desert regions.

FRUIT: Achenes are topped with a pappus of fine bristles.

UNARMED. Thornless.

Asteraceae -- Sunflower Family
