Discussion
Subspecies 2 (1 in the flora).
It is not clear that subsp. speciosum is the best identification for plants in the flora area, if the infraspecific distinction is to be made. Subspecies speciosum is characterized by leaves with grayish, rather harsh tomentum and capsules 3–6 mm; subsp. megaphlomos (Boissier & Heldreich) Nyman is characterized by leaves with a white or yellowish, soft, thick tomentum and capsules 5–7 mm. Distinctly elongate basal and proximal cauline leaves are often found in Verbascum speciosum.
