Type Concept: This association is only known from the Santa Monica Mountains region. This woodland association occurs on gentle to very steep slopes on all aspects at low elevations between 20 and 460 m. It is dominated by Juglans californica in the tree layer, Malosma laurina in the understory shrub layer, and a variety of grasses and forbs in the herbaceous layer.

Floristics: Stands of this association at Santa Monica Mountains National Recreation Area form a sparse to intermittent tree layer (4-40%, mean 14.3%) with hardwoods at 0-15 m tall, an open to intermittent shrub layer (10-55%, mean 27.8%) at 0.5-5 m tall, and a sparse to intermittent herbaceous layer (0-41%, mean 10.9%) at 0-1 m tall. Total vegetation cover is 40-62%; mean cover is 51.2%. In this association, the tree layer is dominated by Juglans californica. Quercus agrifolia and Platanus racemosa are occasionally found at lower cover in this layer. The open to intermittent shrub layer is dominated by Malosma laurina. Frequently, Artemisia californica, Heteromeles arbutifolia, and Malacothamnus fasciculatus are found at lower cover in this layer. A variety of other shrubs is also included in this layer. The herbaceous layer is diverse and includes Leymus condensatus, Bromus sp., Avena sp., Erodium sp., Medicago polymorpha, and Marah macrocarpus.
