Pectis angustifolia

Pectis angustifolia (lemonscented cinchweed) is a summer blooming annual plant which is found in Western North America, generally from Nebraska and Colorado to Arizona and Mexico. It is in flower from July to October, and the seeds ripen from September to October. Lemonscented cinchweed cannot grow in the shade. The plant is carminative and emetic. The crushed leaves have been used in the treatment of stomach aches. Among the Hopi of Arizona it was known as taichima and was eaten boiled with green corn.
