A _Drosera_ key??!!!! REALLY???!!!!
Does this track the genus down to section level, or does it even go beyond
that? How many sections are in _Drosera_?

P.S. For those of you who are struggling to keep your greenhouses warm in
the winter, I remember my first year with my greenhouse---I didn't have a
heater yet so I improvised by modifying very slightly my toaster-oven. It
worked for a few weeks---long enough for me to shop around and find a nice
used electric heater I hooked to a thermostat.
