Mayaca fluviatilis is occasionally found growing in seepage areas and lake margins from the northern counties to the central peninsula of Florida. Bog moss blooms from spring to fall (Wunderlin, 2003).
The stems of bog moss are typically several feet long. The stems are whitish-green. The leaves of bog moss are soft and mossy, like short pieces of fine thread. The leaves are only 1/4 inch long. They are arranged spirally on the stem, and are densely crowded. Bog moss flowers are solitary, on stalks that are one to two inches long. The small, 1/2-inch-wide flowers have three petals and are whitish to pink.
