|---|---|---|---|---|---|
| Commelinaceae | Murdannia keisak | Mud-Annie, Marsh Dewflower | Stream banks, canals, ditches, freshwater marshes (tidal and non-tidal), swamp forests, wet areas in bottomlands, wet disturbed places. | Native of Asia, now widespread in the se. United States. M. keisak was introduced to SC and LA in the 1920s and 1930s, probably as a contaminant in rice seed, but the seeds now distributed by water and waterfowl; it is now a very serious invasive in a wide range of wetland habitats (Dunn & Sharitz 1990). |  |
| Commelinaceae | Murdannia nudiflora | Naked-stem Dewflower | Moist sands, ditches, wet disturbed places. | Native of Asia, now widespread in the tropics and subtropics of both hemispheres. This species apparently arrived in our region earlier than M. keisak (Small 1933, for instance, treats this species and not M. keisak), but has naturalized less aggressively and is distinctly less common. |  |
| Commelinaceae | Murdannia spirata var. parviflora | Asiatic Dewflower | Marshes, wet Florida prairies. | Native of tropical Asia. |  |
