'''''Chorizanthe''''' is a genus of plants in the [[Polygonaceae|buckwheat family]] known generally as '''spineflowers'''. These are small, squat, herbaceous plants with spiny-looking [[inflorescence]]s of flowers. The flowers may be in shades of red or yellow to white. The [[bract]]s are pointed and sometimes tipped with a hooked [[awn]], and the inflorescence often dries into a rounded, spiny husk. Spineflowers are found in western North America and South America.
Selected species:
*''[[Chorizanthe angustifolia]]'' - narrowleaf spineflower
*''[[Chorizanthe blakleyi]]'' - Blakley's spineflower
*''[[Chorizanthe brevicornu]]'' - brittle spineflower
*''[[Chorizanthe breweri]]'' - San Luis Obispo spineflower
*''[[Chorizanthe corrugata]]'' - wrinkled spineflower
*''[[Chorizanthe cuspidata]]'' - San Francisco spineflower
*''[[Chorizanthe douglasii]]'' - San Benito spineflower
*''[[Chorizanthe howellii]]'' - Mendocino spineflower
*''[[Chorizanthe membranacea]]'' - pink spineflower
*''[[Chorizanthe obovata]]'' - spoonsepal spineflower
*''[[Chorizanthe orcuttiana]]'' - San Diego spineflower
*''[[Chorizanthe pungens]]'' - Monterey spineflower
*''[[Chorizanthe rectispina]]'' - prickly spineflower
*''[[Chorizanthe rigida]]'' - devil's spineflower, rigid spineflower
*''[[Chorizanthe staticoides]]'' - turkish rugging
*''[[Chorizanthe stellulata]]'' - starlet spineflower
*''[[Chorizanthe valida]]'' - Sonoma spineflower
*''[[Chorizanthe watsonii]]'' - fivetooth spineflower
*''[[Chorizanthe wheeleri]]'' - Santa Barbara spineflower
*''[[Chorizanthe xanti]]'' - Riverside spineflower
