Zusammenfassung:In 1996, Beckett's water trumpet (Cryptocoryne beckettii) was found growing in the upper San Marcos River (SMR), located in Hays County, Texas, USA (Rosen 2000). The SMR is spring-fed and is home to numerous endangered and threatened species, including Texas wild rice (Zizania texana), Texas blind salamander (Eurycea rathbuni), San Marcos salamander (Eurycea nana), fountain darter (Etheostoma fonti-cola) Comal Springs riffle beetle (Heterelmis comaknsis) and the San Marcos gambusia (Gambusia georgei) now thought to be extinct. Any changes to these species' habitats may prove detrimental to their existence.
