Herb (Chenopodium quinoa) which attains a height of 1.5 m. The small green clustered flowers are succeeded by small fruits each containing a single seed. The seeds are boiled to make a kind of gruel called carapulque. The plant is native to the Pacific slopes of the Andes over about 2400 m above sea level. It was possibly locally domesticated by c.6000 bc, but in general not widely domesticated until c.ad 500.
