Lemna gibba L.(gibbous duckweed or fat duckweed) Would you please tell me what KEY in these pictures determine it is Lemna gibba L. Another species reported from our area is Lemna perpusilla Torrey,but it is having restricted distribution.
Since it has distinct apical papulae, it is not L. gibba. Since it has more than 3 fronds together, it is not L. perpusilla.
It is L. minor L.,, which is distributed throughout India.
