The presence of pseudoroot, which does not exist in any other
member of Wolffia (Landolt, 1986; Maheshwari, 1956) and not even
in any other species of Lemnaceae, deserves attention. For this reason,
it also has diagnostic value. However, sometimes the fronds are
visually devoid of a pseudoroot and it becomes extremely difficult
to identify this species in its almost flat, slightly convex form, as
it was during our recent rediscovery of this plant species from the
lakes at Ambapur and Patan in Gujarat, India. Although Hegelmaier
called the pseudoroot a rhizoid and initially assumed it to be a remnant
ofthe stipe as in some species of Wolffiella (Hegelmaier, 1885),
