Discussion
The closely related cordilleran sp. G. affinis A. Gray has been reported from n. c. Minn. and Huron Co., Ont. It differs in its smaller cor (mostly 2.5–4 cm) and unstable cal, the lobes variously large or small, commonly unequal, sometimes virtually suppressed, the tube often once or twice cleft especially when the lobes are reduced. The lvs are also a little more definitely scaberulous-margined ± throughout their length.
