'''''Cryptocoryne usteriana''''' is a species of aquatic [[herb]] in the family [[Araceae]] endemic to the [[Philippines]].<ref name="tootsie">{{cite web|url=http://apps.kew.org/wcsp/namedetail.do?name_id=52063 |title=World Checklist of Selected Plant Families |publisher=Royal Botanic Gardens, Kew |accessdate=2018-08-31}}</ref> It was named after the German botanist Alfred Usteri<ref>{{cite web |title=Cryptocoryne usteriana, Engler (1905) |url=http://aquaflora.dk/plant-e/besk/cryp-ust.html |website=AquaFlora.dk – your guide to aquatic plants. |publisher=Sven Erik Riedel |accessdate=1 September 2018}}</ref> who discovered the plant in the island-province of [[Guimaras]] in 1902.<ref>{{cite web |title=Usteri, Alfred |url=http://www.nationaalherbarium.nl/FMCollectors/U/UsteriA.htm |website=Cyclopaedia of Malesian Collectors |publisher=P.C. van Welzen |accessdate=31 August 2018 |ref=peter.vanwelzen@naturalis.nl}}</ref> The species can also be found in the mainland [[Panay]], in tributaries of lowland [[bedrock river]] with not too rapidly flowing water and seasonal flood pools. During the summer, its natural habitat dries up and plants undergo [[Cryptocoryne#Crypt melt|complete meltdown]]. The following monsoon rain and inundation triggers the remaining rootstock or rhizome to regrow quickly and send blooms underwater. Due to [[Poaching|overcollection]] for the [[Aquascaping|aquarium trade]], the local government categorized it as [[threatened species]].<ref>{{cite web |title=Updated national list of threatened Philippine plants and their categories |url=http://www.philippineplants.org/dao-2017-11.pdf |website=Co Digital Flora of the Philippines |publisher=Philippine Department of Environment and Natural Resources (DENR) |accessdate=1 September 2018 |archive-date=27 August 2018 |archive-url=https://web.archive.org/web/20180827170155/http://www.philippineplants.org/dao-2017-11.pdf |url-status=dead }}</ref>
