Iris Linnaeus. Common name: Iris, Flag, Fleur-de-Lis, Blackberry-lily.

Key to Iris

A genus of about 225 species, herbs, of Eurasia, n. Africa, and North America. Wilson (2004) suggests that Belamcanda is phylogenetically nested within Iris and should be included there; Goldblatt & Mabberley (2005) make the appropriate nomenclatural combination. Alternatively, Iris may be broken up into multiple genera (Mavrodiev et al. 2014; Crespo, Martínez-Azorín, & Mavrodiev 2015; Mavrodiev et al. 2021).

Key advice:The petals are usually erect, smaller than the petaloid sepals (which are brightly colored, generally reflexed, and marked with a "signal"). The styles are also petaloid, arched over the sepals, and 2-cleft at the tip (except in I. domestica).
