Flattened leaves:
And now I bring us back to the plant with the foliage
that I alluded before; you know, the
foliage sitting on the water in this image.
The mystery plant, shown above, is of course Utricularia intermedia. This plant is recognizable
by the flattened leaf segments with the large number of marginal setulae (i.e. little bristles).
Later microscope observations of the quadrifid glands of these plants revealed normal arm-orientations (more or less
bi-parallel). These plants could not be excusably confused with U. ochroleuca.
