ABOUT FAMILY (Weakley Flora)
Iridaceae A.L. de Jussieu 1789 (Iris Family)
SUMMARY: A family of about 65-82 genera and 1700-1810 species, herbs, of cosmopolitan distribution (most diverse in s. Africa).
REFERENCE: Goldblatt in FNA (2002a); Goldblatt, Manning, & Rudall in Kubitzki (1998a).
ABOUT GENUS (Weakley Flora)
Iris Linnaeus 1753 (Iris, Flag, Blackberry-lily)
SUMMARY: 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).
REFERENCE: Crespo, Martínez-Azorín, & Mavrodiev (2015); Henderson in FNA (2002a); Goldblatt in FNA (2002a); Mavrodiev et al. (2014); Goldblatt & Mabberley (2005)=Z; Wilson (2004); Goldblatt, Manning, & Rudall in Kubitzki (1998a). Key based on Henderson in FNA (2002a).
