Aquatic plant for identification -1: Can you identify the small leaved free floating aquatic plant. I guess it is Wolffia, pls confirm. And also identify the species. Location: Chennai Date : October 2011 I m sorry for the large file size. I will reduce the photo with better programs next time. My other guess for this plant is is Lemna sps. It may be Spirodela polyrhiza (Araceae). Fronds purplish beneath; and roots are many as seen in the posted picture. I think there are more than one species floating there which is not so unusual. Lemna, Spirodella, Wolffia..... Please check... Yes there are many species. But I am aiming at what Vijaysankar metioned as Spirodella polyrrhiza. Here's one more close up of the same plant.
