In cross section they appear lobed. Common shrub associates within the chaparral community include toyon.[6] Leaves and stemsThe leaves are distinctive in that they have smooth edges from the base to about half way up, then are wavy or toothed to the rounded tip.[2] Betula is the birch genus, and the species name refers to the birch-like leaves.[2]Inflorescence and fruitThe white flowers are small, clustered, and mildly scented, similar to acacia.[2] 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
There are three varieties:[7][8]
UsesThe reddish {{citation needed|date=July 2014}} 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.[2] 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.[15][16]References1. ^The Plant List, Cercocarpus montanus var. glaber (S.Watson) F.L.Martin 2. ^1 2 3 4 5 6 7 8 Flowering Plants of the Santa Monica Mountains, Nancy Dale,2nd Ed, 2000, p. 170 3. ^Calflora taxon report, University of California, Cercocarpus betuloides Torrey & A.
