a Preston e-mail of 5 Jul 2000, "Ponds, lakes, reservoirs, canals; NCoR (Napa, Sonoma cos.), SCo, DSon (Colorado River); native to S. Am.; California Exotic Pest Plant Council (CalEPPC). 1999. Exotic pest plants of greatest concern in California. Oct, 1999. San Juan Capistrano, CA."
b Hrusa et al., ms later published in Madrono 49(2)61-98. 2002: DISTRIBUTION: SCo, Dson.; STATUS: established (DSon). tenuous (SCo).; NOTES: Noxious Weed listing by California Dept. of Food and Agriculture (CDFA) is as Salvinia auriculata Aubl. sensu lato. Acc. to D.S. Mitchell, North American material is probably all S. molesta (pers. comm. C. Jacono, USGS), but routine determination below Salvinia auriculata complex is problematic. Eradication attempts currently underway by CDFA, USDA-APHIS. Despite attempts by the Agricultural Commissioners Offices in every county of the state to restrict its sale, this species defiantly continues to be sold throughout California by commercial nurseries, pet stores, fish dealers and others with an interest in aquatic vegetation. Interstate shipment or sale is monitored by USDA-APHIS, but Interstate internet sales continue almost unabated. Nurseries selling this species are sometimes forced to appeal to their Agricultural commissioner's offices for help controlling it in their own facilities, underscoring the dangerously aggressive and rapid nature of its growth pattern. It may be found sold under the common names of "salvinia", "water velvet", and "water fern" among others.
