Cercocarpus ledifolius Nutt.
Curl-leaf Mountain Mahogany, Curl-leaf Mountain-mahogany
Rosaceae (Rose Family)
USDA Symbol: cele3
USDA Native Status: L48 (N)
Curl-leaf mountain-mahogany is a 10-20 ft., sometimes taller, evergreen shrub or small tree with white bark and small, leathery leaves - dark-green on top and silvery underneath. Slightly resinous and aromatic evergreen shrub or small tree with compact, rounded crown of widely spreading, curved, and twisted branches and many stiff twigs. The leaves are narrow and pinched at the mid-rib, then bent to one side, hence the name curl-leaf. The flowers are inconspicuous, but the short, spiral, silver-haired seed plumes are eye-catching. The whole plant has a spicy aroma.
This species is a small tree characteristic of lower mountain slopes throughout the Great Basin. Deer browse the evergreen foliage year-round. The hard, heavy wood is an important source of fuel in local mining operations; it is also used for novelties, as it takes a high polish. The name "Mountain-mahogany" applied to this genus is misleading; these shrubby trees are not related to true mahogany (Swietenia), a valuable cabinetwood of tropical America. The dark reddish-brown, mahogany-colored heartwood may have led to this name. Navajo Indians made a red dye from the roots by grinding and then mixing them with juniper ashes and powdered alder bark.
