nr A HE fronds float in little patches among duck-weed, and
other fuch plants, on the furface of ponds and ditches, emitting
a few fliort roots from the under fide. Each frond is forked
or branched in an alternate manner feveral times, its margin
entire, fubflance pellucid, but not membranous, the tips blunt,
often bifid, with little darkifh fpots near the extremity (fee our
magnified figure), which we dare not afiert to be the feed-
vefiels, nor has any botanift yet feen the fruaification in any
fhape. There being fo little hope of difcovering it mull be
our apology for exhibiting the plant without, more efpecially as
it is a vegetable very little known,, and which we beg leave to
recommend to the examination of the curious.
