Adenostoma fasciculatum (Chamise)

Plants: This common densely branched woody shrub reaches as much as 13′ (4 m) in height. Bark is gray-brown in color.

Leaves: ⅛–⅜ ⨉ 1/32″ (4–10 ⨉ 1 mm), dark- or yellow-green, linear, needle-like, shiny, attached spirally in fascicles, or tight clusters. They are highly flammable, owing to the presence of oils. (Despite this flammability, chamise recovers quickly after fires because its crown regenerates from its base.)

Flowers: Inflorescences are up to 7″ (17 cm) long. Flowers hang on short pedicels. They are small, white, inconspicuous, with 5 petals and 10-15 stamens, in cone-shaped groups up to 1½–4½″ (4–12 cm) long.

Fruits: A small, ovoid achene, which develops within the hypanthium and disperses with the hypanthium as a single unit
