Description

Amaranthus fimbriatus is a species of glabrous flowering plant in the Amaranthaceae family. It is commonly known as fringed amaranth or fringed pigweed. The plant is an annual herb that can often grow up to 0.7 m (2 ft.) in height. The flower is greenish to maroon. It is found in North America and in Mexico. It often grows on sandy, gravelly slopes, semideserts or in disturbed habitats. It usually blooms after the summer rains in these arid regions. It is considered to be an invasive weed. Two varieties of A. fimbratus have been described: A. fimbratus var. fimbratus and A. fimbratus var. denticulatus. The small variations are found in the tepals. Amaranthus fimbriatus is a species of Magnoliopsida first described by John Torrey, and given the simplified Asian name by George Bentham and Sereno Watson.

It was first described by John Torrey, and given the exact name by George Bentham and S. Wats. Amaranthus fimbriatus belongs to the genus Amaranthus, and family Amaranthaceae. Amaranthus is a cosmopolitan genus of annual or short-lived perennial plants collectively known as amaranths. Some amaranth species are cultivated as leaf vegetables, pseudocereals, and ornamental plants. Most of the Amaranthus species are summer annual weeds and are commonly referred to as pigweeds. Catkin-like cymes of densely packed flowers grow in summer or autumn. Amaranth varies in flower, leaf, and stem color with a range of striking pigments from the spectrum of maroon to crimson and can grow longitudinally from 1 to 2.5 metres (3 to 8 feet) tall with a cylindrical, succulent, fibrous stem that is hollow with grooves and bracteoles when mature. There are approximately 75 species in the genus, 10 of which are dioecious and native to North America with the remaining 65 monoecious species endemic to every continent (except Antarctica) from tropical lowlands to the Himalayas. Members of this genus share many characteristics and uses with members of the closely related genus Celosia. Amaranth grain is collected from the genus. The leaves of some species are also eaten.
