I have two further additions:
Subgen.Drosera Sect.Oosperma - _D.burkeana_ (20) (Kondo, Bull. Torr.
Bot. Cl.96:324, 1969)
Sect.Drosera - _D.slackii_ (40) (Bennett & Cheek, Kew Bull.
45:380, 1989)
> D.venusta (40), D.admirabilis (40) (the latter 2 = D.aliciae?)
No. D.venusta is _D.natalensis_, D.admirabilis is _D.cuneifolia_.
> Subgen.Bryastrum Sect.Bryastrum - D.pygmaea (I found several from 20-34)
Is this sufficient for you to believe that there may be several
different karyotypes *within* a single species of Bryastrum, Juerg?
Kind regards
Jan
