'''''Ambrosia ambrosioides''''', also known as '''canyon ragweed''' or '''chicura''' is a [[ragweed]] found in the deserts of northern [[Mexico]] and ranging into the southern half of [[Arizona]].<br />
<br />
Growing as a [[shrub]] from 1-2 meters high, its elongate, coarsely-toothed leaves range from 4-18 cm long and 1.5-4 cm wide. It is [[monoecious]], with both terminal and axillary [[raceme]]s consisting of [[staminate]] heads occurring above their [[pistillate]] counterparts. Flowering occurs mainly in February through April. The fruits are 10-15 mm burs covered with hooked spines.<br />
<br />
Somewhat similar in appearance to ''[[Ambrosia ilicifolia]]'', ''A. ilicifolia'' has sessile leaves with a reticulate pattern of veins, and the marginal teeth developed into short spines.<br />
<br />
This ragweed can be found in sandy washes and other disturbed areas such as roadsides, and is sometimes seen growing in rock crevices.<br />
<br />
Although widespread in the Mexican and Arizonan parts of the [[Sonoran Desert]], it seems not to occur in [[California]]; [[Philip A. Munz|Munz]] reported it near [[San Diego, California]], but no specimens have been vouchered. Its northern limit is governed by winter frosts.<br />
<br />
The [[Seri]] people smoked its dried leaves, and used the roots to make medicinal teas and pigments.<br />
