Amaranthus Hybridus Erythrostachys
Var. erythrostachys has a crimson inflorescence and is cultivated as an ornamental. Var. hybridus has a smaller green inflorescence and is often confused with the other weedy amaranths (Webb et al 1988).
amaranthus hybridus erythrostachys
Canada (Ontario), USA (eastern), Mexico, Central America, South America (northwestern). Widespread as a weed in warmer parts of the world. Introduced in Euromediterranean region, Western Asia (Arabia to Pakistan), Himalayas, India, Sri Lanka, Indochina (except Myanmar), China, Japan, Korea, Africa (except Mauretania, Niger, Somalia, Mozambique), Canada (British Columbia, Québec), USA (western), Caribbean, South America (beyond its original range), Australia (except Tasmania)WSSA list of weeds in North America.A. hybridus is the wild progenitor of several cultivated amaranths: A. caudatus, A. cruentus (q.v.), A. hypochondriacus (q.v.). These plants are grown as ornamentals or for their grain, they do not exist in the wild, and are not weeds. A. patulus Bertoloni is a spreading form of A. hybridus.There is continuing disagreement whether the correct name for the whole complex should be A. hybridus or A. cruentus. The situation appears to be inextricable.
Amaranthus hybridus (Slim Amaranth) is a species of annual herb in the family Amaranthaceae. They have a self-supporting growth form. They are associated with freshwater habitat. They are native to The Contiguous United States. They have simple, broad leaves and capsule fruit. Flowers are visited by Euphoria basalis. Individuals can grow to 0.5 m.
All six species of Amaranthus contained alkaloids. Saponins were absent in A. graecizans L. and A. retroflexus L. but were present in the other species. Since A. retroflexus L. and A. hybridus L. and its variety erythrostachys The 11. are very similar morphologically, the hemolysis test provides a confirmatory test for differentiating between them and affords a good chemotaxonomic criterion. Very little tannin was present in Amaranthus species with the exception of A. hybridus L. and its variety erythrostachys The 11. which showed a much higher tannin titer. 041b061a72
