The infraspecific taxonomy of the species is complicated and in a state of flux. A number of subspecies and varieties have been published, but these have long been recognised as not accurately reflecting variation within the species. In 2004 a thorough study of the species found ten variants, but did not publish names for them because further nomenclatural work was required for this. The following year a new revision, was published, in which the following varieties were recognised:
