Calif., nw Mexico.
Species 2 (2 in the flora).
Adenostoma is a Madro-Tertiary derivative of a lineage with compound leaves. Seedlings and sucker shoots have 1–2-pinnatifid leaves; mature leaves are simple, undivided. Both species occur in chaparral and resprout after fires from basal lignotubers. The single achenes are derived from ancestral 5-follicled fruits, each carpel retaining the ancestral marginal style. Stamens are arranged in groups of 2 to 3 alternate with petals; filaments expand sequentially, first 5 (1 opposite each sepal), followed by the second 5 and third 5 (when 15).
