Cercocarpus betuloides explained

Cercocarpus betuloides is a shrub or small tree in the rose family.[1] Its common names include mountain mahogany and birch leaf mountain mahogany[1] [2] The common name "mahogany" comes from the hardness and color of the wood, although the genus is not a true mahogany.[1]

Range and habitat

The plant is native to California, Baja California, Oregon, Arizona, and northwestern New Mexico.[3] It typically grows in summer dry areas of the foothills and mountains of California, often in chaparral communities.[1]

Description

Growth pattern

Cercocarpus betuloides is a shrub or small tree growing from 3feet to 30feet.[1] [4] Its branches are incised and muscular in appearance from the side. In cross section they appear lobed.

Common shrub associates within the chaparral community include toyon.[5]

Leaves and stems

The leaves are distinctive in that they have smooth edges from the base to about halfway up, then are wavy or toothed to the rounded tip.[1]

Betula is the birch genus, and the species name refers to the birch-like leaves.[1]

Inflorescence and fruit

The white flowers are small, clustered, and mildly scented, similar to acacia.[1]

The fruit is a tubular achene with the long, plumelike flower style still attached.

The genus name comes from the Greek kerkos ("tail"), referring to the tail-like appearance of the fruit; and carpus ("fruit"), thus, "fruit with tail".

Taxonomy

VarietiesThere are three varieties:[6]

Cercocarpus betuloides is sometimes treated as a part of Cercocarpus montanus,[11] var. glaber in particular.[12]

Uses

Deer, cattle and sheep browse the plant.[13]

The reddish wood of the shrub is very hard and was traditionally used by the indigenous peoples of California to make arrow tips, fishing spears, and digging sticks.[1]

Cercocarpus betuloides is cultivated as an ornamental plant by specialty nurseries for planting in native plant, drought tolerant, and wildlife gardens; and in designed natural landscaping projects and habitat restoration programs.[14] [15]
