It is found growing in swampy areas, at edge of pond and tanks, beside streams, in ditches, in or around rice fields. Grows in shallow water up to 0.3 m, in seasonally dry and open habitats. It is an annual, short to intermediate height (usually <2 m) grass; panicles usually compact, rarely open; spikelets large, 6-10.4 mm long and 1.9-3.4 mm wide, with strong awn (4–10 cm long); anthers 1.5–3 mm long. Its distribution includes Bangladesh, Cambodia, China, India, Laos, Malaysia, Myanmar, Nepal, Sri Lanka, Thailand, and Vietnam. Recently, the genome of O. nivara was sequenced.[2] References1. ^{{cite journal | author1 = Phillips, J. | author2 = Yang, L. | author3 = Vaughan, D. | title = Oryza nivara | journal = IUCN Red List of Threatened Species | volume = 2017 | page = e.T112680564A113899490 | publisher = IUCN | year = 2017 | url = http://www.iucnredlist.org/details/112680564/0 | doi = 10.2305/IUCN.UK.2017-3.RLTS.T112680564A113899490.en | accessdate = 7 May 2018}} {{Taxonbar|from=Q7105330}}{{Poaceae-stub}}2. ^{{Cite journal | last1 = Zhang | first1 = QJ. | last2 = Zhu | first2 = T. | last3 = Xia | first3 = EH. | last4 = Shi | first4 = C. | last5 = Liu | first5 = YL. | last6 = Zhang | first6 = Y. | last7 = Liu | first7 = Y. | last8 = Jiang | first8 = WK. | last9 = Zhao | first9 = YJ. | last10 = Mao | first10 = Shu-Yan | last11 = Zhang | first11 = Li-Ping | last12 = Huang | first12 = Hui | last13 = Jiao | first13 = Jun-Ying | last14 = Xu | first14 = Ping-Zhen | last15 = Yao | first15 = Qiu-Yang | last16 = Zeng | first16 = Fan-Chun | last17 = Yang | first17 = Li-Li | last18 = Gao | first18 = Ju | last19 = Tao | first19 = Da-Yun | last20 = Wang | first20 = Yue-Ju | last21 = Bennetzen | first21 = Jeffrey L. | last22 = Gao | first22 = Li-Zhi | title = Rapid diversification of five Oryza AA genomes associated with rice adaptation | journal = Proc Natl Acad Sci U S A | volume = 111 | issue = 46 | pages = E4954–E4962 | date=Nov 2014 | doi = 10.1073/pnas.1418307111 | pmid = 25368197 | display-authors = 8 | pmc=4246335}} 2 : Oryza|Flora of tropical Asia |
