Use: Stansbury cliffrose is a highly important winter browse plant for cattle, sheep, and deer. Generally, it is not as palatable as bitterbrush; but on some winter ranges, it is more palatable than bitterbrush--probably because of its more evergreen habit. In southern Arizona, Stansbury cliffrose is not palatable. Accessions from this area have a different two-dimensional chromatogram of phenolic compounds than palatable populations from northern Arizona and central Utah (E. D. McArthur and R. Stevens, 1972. Chromatography information on file at Intermountain Forest and Range Experiment Station, Ephraim, Utah). Fallugia paradoxa (Apache plume) Apache plume is a much-branched, often evergreen shrub, 1 to 2 m tall (fig. 25). Leaves are borne in clusters along branchlets. They are pinnately divided into three to seven linear lobes with revolute margins. The large, white, showy, solitary, perigynous flowers, 25 to 38 mm broad, are usually borne at the ends of slender, elongated peduncles. The typical flower has five sepals that alternate with five supplementary bractlets giving the appearance of 10 sepals, five free-spreading white petals, numerous stamens inserted in three series on the margin of the hypanthium, and numerous pistils. The numerous short, hairy achenes, 3 mm or less long, produced by this species are tailed by long, reddish plumose persistent styles 25 to 38 mm long (fig. 26). The styles turn white when the seed matures. Apache plume averages approximately 420,000 cleaned seeds per pound (925/g)( Forest Service 1948).. Figure 25.—Pistillate flowers of Ayaohe plume sho
