Mary Ester and George Bollis (Class of 2020) visited T.M. Goodwin Waterfowl Management Area located on the east side of the St. Johns River in southern Brevard County. There they photographed Virginia saltmarsh mallow (Kosteletzyka pentacarpos), which we see at the Oslo Riverfront Conservation Area, Toni Robinson Waterfront Trail, and other places.
Mary Ester observed that some of the plants had white flowers, researched, and discovered that white fenrose (Kosteletzyka depressa) was growing there …
Monroe and Miami-Dade supposedly are the only counties in which this tropical plant is found, according to the Florida Plant Atlas. Mary Ester pointed out that the pink-flowered plants have a pink stigma, while the white-flowered plants have a white stigma.
Be on the lookout for white fenrose, thanks to Mary Ester!
