Yes - Tony moved Ileostylus from Benge Part to Te Maruia Forest. I dont' know if anyone has succeeded with Korthalsella - but Amir Sultan's PhD (Massey University, Supervisor Alastair Robertson) may offer some advice. Also try talking to David Havell (dhavell@doc.govt.nz) as he had quite an interest in K. salicornioides. There is also a student - whose name alludes me for now - working on the genetics of the N.Z. members of genus under Dr Jen Tate (j.tate@massey.ac.nz) - also at Massey who might be able to help.
