Taxon concept:

 Key to the subspecies 
1Leaves with lower surface with an open indumentum of ascending 2-branched hairs (often also with simple erect glandular hairs); outer surface of perianth with simple erect hairs (mixed among ascending 2-branched hairs) usually confined to the basal third, occasionally more extensivesubsp. rhyolitica
Leaves with lower surface with scattered minute closely appressed 2-branched hairs (surface sometimes appearing glabrous); outer surface of perianth with simple erect hairs (mixed among ascending 2-branched hairs) distributes over the whole surface, including limb segmentssubsp. semivestita
