Keying Drosera

Fri, 25 Feb 1994 11:21:24 -0500 (EST)

I'd like to get started keying out some unknown rosetted _Drosera_
which I have. Is there a good single (few) source reference(s) for this or
do I need to start collecting type descriptions? These plants were in some
pots of _Sarracenia_ I got last year, but may not be of North American origin.
Suggestions? Thanks!
