Amaranthus spinosus is an erect, much-branched annual plant growing up to 100cm tall. The plant is harvested from the wild for local use as a source of food and medicines. The leaves are sometimes sold as a vegetable in local markets. A pantropical weed, extending sometimes into the temperate zone, it originally came from Tropical America.
