Note,—Iris nepalensis is usually—by Mr. Baker, for instance, and 85 others—included in the Evansia section or subgenus, by reason of theconspicuous median ridge (crest) on the fall. As I have elsewhere(Gard. Chron. 1887, i. p. 611) urged, though the group Evansia seemsto me a natural group, I cannot attach any importance to the ridge onthe fall.
