Nothing is known to me about this but it does not seem very probable. BTW,
Some _Drosera_ species which are perennial in regions with humid summers
seem to become annuals in regions with dry summers in Brazil (F.RIVADAVIA,
pers. comm.). The *southernmost* records of _D.intermedia_ are already from
the "lower" end of the tropical zone (S Brazil- non vidi, F.RIVADAVIA pers.
comm.).

Yes, more or less. The (always glandular) indumentum on the scapes of
_D.brevifolia_ is usually much denser than in the other two species (which
do usually not flower in a stage at which their leaves are so small that
the rosettes could really be confused with those of _D.brevifolia_).
The best distinguishing feature (in the absence of seeds, which are
diagnostic in all 3 species) is in the stipules, however. These are reduced
to two very inconspicuous and sometimes deciduous lateral setae in
_D.brevifolia_, so they are usually not even noticed by the unexperienced
observer, while the stipules of _D.intermedia_ and _D.capillaris_ are well
developed.
