This widespread species exhibits wide variation across its geographic range. Several infraspecific taxa have been described, but these are not always distinct. This, and the following four species are morphologically very similar and further work is needed to define the taxa clearly. At least var. candollei has reputed medicinal value.

1 Stem, bracts and bracteoles purplish-red; leaf blade abaxially not glaucous.   12b var. atropurpureum
+ Stem, bracts and bracteoles green; leaf blade abaxially glaucous.   (2)
2 (1) Stem moderately branched; basal leaves not spatulate, petioles short.   12a var. candollei
