Cercocarpus betuloides Torrey & A. Gray var. betuloides

Birch-leaf Mountain Mahogany
Rosaceae (Rose Family)


 

Birch-leaf mountain mahogany is one of the two common mountain mahoganies found in Southern California, the other being curl-leaf mountain mahogany, Cercocarpus ledifolius var. intermontanus, which typically grows above 4500'.  Although birch-
leaf mountain mahogany can reside up to 7500', it also may be found at much lower elevations.  This is a much-branched shrub or small tree sometimes reaching 20' in height with stiff, spreading branches and grayish bark.  The alternate evergreen leaves are widely elliptic to obovate, serrately-toothed from middle to tip, fairly thin and sparsely downy-hirsute below, and 1/3" to 1-1/2" in length.  There are clusters of 2-3 apetalus flowers arising from short whitish stems, each of which has 5 broad-triangular sepals and many stamens.  The fruits have spiral, somewhat silky plumes 1-1/2" to 2" long, and are particularly beautiful when an early morning or late afternoon sun shines through them.  Birch-leaf mountain mahogany is most often found on dry, rocky slopes in chaparral and coniferous forest in the Transverse and Peninsular Ranges, blooming from March to April.
