Discussion

Subspecies 3 (1 in the flora).

(Discussion copyrighted by Flora of North America; reprinted with permission.)

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.

(If the plant you're looking for doesn't show up in the auto-complete list, that means it either isn't described in Flora of North America yet, or it's listed under a synonym. And please note that Flora of North America is still missing several plant families, including Fabaceae, Apiaceae, Boraginaceae, and Polemoniaceae.)
