Monterey Spineflower

Scientific Name: Chorizanthe pungens var. pungens

Status: T, CH

The Monterey Spineflower is an annual herb belonging to the Buckwheat Family. It is distinguished by white (rarely pinkish) scarious margins on the involucral lobes and a prostrate to slightly ascending habit. The aggregate of flowers (heads) tend to be less than 1 cm in diameter and either distinctly or indistinctly aggregate.

Habitat: Scattered on sandy soils within coastal and near-coastal dune, coastal scrub, grassland, maritime chaparral, and oak woodland communities. Found in open areas, openings between shrubs, roadsides, firebreaks. Native to California and endemic (limited) to California alone.

Threats: Much of this species' habitat has been destroyed or degraded by urbanization, agricultural development, and the introduction of non-native plants for dune stabilization.
