editorial
Healy and Edgar (1980) identified the naturalised Allium roseum in New Zealand as Allium roseum subsp. bulbiferum, based on the observation that the inflorescences of these plants produced both bulbils and flowers. However, Allium roseum subsp. bulbiferum has since been synonymised with the type subspecies, Allium roseum subsp. roseum. The presence of bulbils is now considered an unreliable characteristic for subspecies distinction.
