I'm fairly certain this is a fern of some type but I don't have any handy references to lead me to an ID. Any help would be appreciated. Photographed on the trunk of a tupelo or other hardwood in the Corkscrew Swamp Sanctuary. The individual strap-like fronds are about 3" to 12" long, if I recall correctly.
This was a surprise. I've probably driven past these clusters of alligator flag at the edge of a detention pond dozens of times but never noticed or identified them. There are 3 or 4 clusters of plants around the edges of this pond. I would think these plants are undoubtedly introduced here in Central Texas for water quality purposes.
I just *learned* this plant in the cypress swamps of southern Florida in September (and will be uploading those images shortly).
This tall shrub/small tree was photographed along Island Inn Road, not far off of West Gulf Drive on Sanibel.
Common around the edge of lakes and edges of the swamp at Six-mile Cypress Slough Preserve in Fort Myers. Note the Alligator-flag arrising from the cluster of vines.
Along the Indigo Trail near the HQ of J.R. Ding Darling NWR on Sanibel.
These were planted in the yard of the house where we stayed on Sanibel but the species was also seen here and there along roadsides and ditches elsewhere on the island. It was one of the few good butterfly plants we noted, attracting a few of the large skippers.
USDA PLANTS database now includes R. brittoniana (along with R. simplex) as a synonym of R. coerulea, while ITIS uses R. simplex for the other two taxa. Let's have an arm-wrestling match over this.
This constituted a new family of plants for me, the Goodeniaceae. The USDA PLANTS database has the common name "Gullfeed" for this curious dune shrub.

I'm placing this observation of "Yellow necklace pod" under the native variety in south Florida, presuming this shrub in the margins of native woods at Lighthouse Beach was a natural occurrence and not a planted variety. I didn't get a usable close-up of the flowers.
