Marc, I can see your confusion. Some experts say it is indeed a true original species. Others say that it probably is not a true original species. The authors of Citrus Genetics, Breeding & Biotechnology are explaining this disparity between the experts in the citrus industry. Luro, Herrero and Fang, who are also quoted in the same book say that their research shows that indeed Halimii is an original species and not a variety. Until Halimii's status is forever settled, we can join either side, or no side, of the discussion that you feel more comfortable with. - Millet (913-)
