Zornia latifolia Sm. (Fabaceae) is a perennial herb, known for reported psychoactive and medicinal properties, with a native range from Argentina to South Texas and some West Indian islands. There is disagreement on the status of Z. latifolia in Florida concerning whether it is a native species, an established non-native species, or a waif (i.e., a non-native species growing outside of cultivation, but not maintaining a viable population). In Florida, there is only one published record of Z. latifolia growing outside cultivation, in Hillsborough County, but multiple records of this species cultivated for research. I observed extensive populations of Z. latifolia in St. Lucie, Martin, Palm Beach, and Orange counties, and confirmed observations posted on-line from Hillsborough County. Based the recentness of its first record of growing outside cultivation in Florida (2015), its substantial persistent populations at multiple locations in peninsular Florida, and its occurrence primarily in and adjacent to mowed areas, Z. latifolia appears to be an established non-native species in the state. Whether it becomes a major invasive species in Florida remains to be seen.

Stylosanthes viscosa (L.) Sw. (Fabaceae) is a herbaceous legume with a native range that includes much of the Neotropics, from Argentina to Texas and several West Indian islands. Except for native populations in Texas, there are no published records of this species growing outside cultivation in the continental United States. Here, I report extensive populations of S. viscosa in southeastern Florida, often growing in near monoculture, with an observed range spanning more than 35 km from Lakewood Park to Port St Lucie in St Lucie County and to Jensen Beach in northernmost Martin County. These populations may have descended from plants imported from Brazil and grown at the Agricultural Research Center (now the Indian River Research and Education Center) in Fort Pierce, St Lucie County, where at least one field of this species growing in near monoculture persists. Stylosanthes viscosa has the potential of becoming a dominant invasive species in and adjacent to open habitats in peninsular Florida.
