Duration: Perennial Nativity: Native Lifeform: Subshrub General: Subshrubs or shrubs, to 1 m tall, plants rounded, densely branching from bases, herbage glandular-puberulous. Leaves: Thin, opposite or alternate, distal often alternate, lanceolate to lance-ovate, deltate, or rhombic, 2-10 mm long or more (but usually shorter than the petioles), margins generally few-toothed, 1 or 3-nerved, margins with few, sharp teeth, faces glabrous and usually stipitate-glandular, petioles thread-like, 2-6 cm long. Flowers: White in discoid heads, disc florets 25-30, corollas 4-5 mm long with narrowly cylindric throats, heads 6-11 mm long, involucres obconic, 4-6 mm diameter, strongly graduated, phyllaries persistent, dry, few-ribbed; outer short, ovate, with acute subherbaceous tips, inner lanceolate, with recurved and darker tips, 2.5-6 mm long, about 25 in 3-5 series, herbaceous to papery (chartaceous), surfaces glandular, 1- or 3-nerved, receptacles flat or convex, epaleate, styles glabrous with club-shaped (clavate) branches, heads borne singly or in loose, panicled or corymbiform arrays. Fruits: Cypselae (achenes) prismatic, 4-5-ribbed, 3-4 mm long, surfaces scabrellous. Pappi persistent, of subulate-aristate scales 10-12, 1-2 mm long (rarely more), and 3-12 coarse, barbellate bristles 1-5 mm long, these in 1 series. Ecology: Found on limestone outcrops and rocky slopes, in washes, crevices of canyon walls, and among creosote bush scrub or acacia-mesquite communities, from 0-700 ft (0-213 m); flowering October-June. Distribution: Arizona, California, Nevada, Utah; Mexico Notes: Look for this somewhat weedy-looking species with urn-shaped flowers and conspicous, dark-tipped phyllaries in Mohave, Yuma, and Pima counties in Arizona. Ethnobotany: Unknown. Synonyms: Hofmeisteria pluriseta Editor: LCrumbacher2012 Etymology: Pleurocoronis comes from the Greek pleurikos, "rib or side," and the Latin corona, "crown," referring to the pappus, whlie pluriseta means many-bristled.
