Kochia scoparia (L.) Schrad.
Bassia scoparia (syn. Kochia scoparia) is a large annual herb in the family Amaranthaceae native to Eurasia. It has been introduced to many parts of North America, where it is found in grassland, prairie, and desert shrub ecosystems. Its common names include burningbush, ragweed, summer cypress, mock-cypress, kochia, belvedere, Mexican firebrush, and Mexican fireweed.
The seed of Bassia scoparia is dispersed by wind and water, and it is transported when the whole plant detaches and rolls on the wind as a tumbleweed. The seed does not persist in the soil seed bank, dying within about a year if it fails to germinate.
This plant is grown as an ornamental for its red fall foliage. It has also been useful in erosion control on denuded soils. It has been suggested as an agent of phytoremediation, because it is a hyperaccumulator of chromium, lead, mercury, selenium, silver, zinc, and uranium.
In Japan the seeds are used a food garnish called tonburi (とんぶり) (Japanese). Because its texture is similar to caviar, it has been called "land caviar", "field caviar", and "mountain caviar". It is a chinmi, or delicacy, in Akita prefecture. The glossy, greenish black seeds are dried, boiled, soaked, and then rubbed by hand to remove the skin.
The seeds are used in traditional Chinese medicine to help regulate disorders such as hyperlipidemia, hypertension, obesity, and atherosclerosis. In a study of mice fed a high-fat diet, an extract of the seeds limited obesity. They contain momordin Ic, a triterpene saponin.
The plant is a moderately useful forage for livestock, especially on dry lands. However, its use is limited by its toxicity in large quantities. Livestock ingesting large amounts can experience weight loss, hyperbilirubinemia, photosensitization, and polyuria.
The species was first published in 1753 by Carl Linnaeus, who named it Chenopodium scoparium. In 1809, it was placed in the genus Kochia by Heinrich Schrader. It was transferred to Bassia in 1978 by Andrew John Scott. Kochia was included in Bassia in 2011 following phylogenetic studies.
