Amazon wild rice refers to either of the two native (endemic) species of rice (Oryza) found in the Amazon region of South America and adjacent tropical areas, Oryza glumaepatula and Oryza latifolia. It also can refer to the cultivated form Oryza sp. (unnamed rice species) which was domesticated from one or both of the wild forms some 4,000 years ago by the indigenous people of the Amazon region.[1] South America actually has 4 indigenous wild rice species, Oryza alta, Oryza latifolia, Oryza grandiglumis, and Oryza glumaepatula,[1] all of which can be found in the Amazon basin of Brazil and could therefore be considered Amazonian wild rice.

Well, that’s interesting to know that Psilotum nudum are known as whisk ferns. Psilotum nudum is the commoner species of the two. While the P. flaccidum is a rare species and is found in the tropical islands. Both the species are usually epiphytic in habit and grow upon tree ferns. These species may also be terrestrial and grow in humus or in the crevices of the rocks.
