Back to these. I have been told that the difference can be seen in the length of the anther. Z. carinata's one measures 2cms before the pollen have developed, the Z. grandiflora's one measures 1.5cms. In which case I have the Z. carinata, not the Z. grandiflora. Alberto and German Roitman, would you know if this is the case? Or anyone else out there. Ina -- Ina Crossley Auckland New Zealand Zone 10
