Schkuhria pinnata, the canchalagua or dwarf Mexican marigold, is a small, dainty, pioneer annual herb of the family Asteraceae and widespread in the tropics.

Reaching 30–60 cm in height, this species is found as a pioneer on disturbed ground such as roadsides and ploughed lands.

Achenes are narrow-turbinate, 4-angled and some 4 mm long; there are 8 membranous pappus scales, darkly striated at apex.

[citation needed] The plant is native to South America, normally found in drier mountainous regions of 2000 – 3000 meters in elevation, and growing abundantly in the inter-Andean valleys.
