Abstract: Floral glandular structures and especially trichomal elaiophores evolved multiple times independently in the American tribes of Iridoideae. The distribution pattern of species displaying glandular trichomes across the phylogeny reveals lability in the pollination system and suggests that these structures may have played a significant role in the diversification of the Iridoideae on the American continent.

“…In Tigridieae, the tepals may have nectaries, but these are variable (Rudall et al 2003, Chauveau et al 2012. Nectaries are found on the adaxial surface of the exterior or interior tepals or on both.…”

“…Cypella geniculata and C. oreophila were included by Ravenna (2009) in Phalocallis based on the same distinctive floral traits than the type species of the genus. Furthermore, the latest comprehensive phylogeny of Tigridieae confirmed that Phalocallis should be regarded as a separate genus from Cypella (Chauveau et al 2012). The resulting circumscription of Cypella shows that 80% of the species and subspecies are found in the Río de la Plata grasslands (RPG), one of the most extensive biogeographic units of the grassland biome in the world (Medan et al 2011).…”

“…The Iridoideae, with more than 900 species, represent one of the two major evolutionary branches of the family and make up about 44% of the species richness of the Iridaceae . Among the five tribes of this subfamily, the New World tribe of Tigridieae forms a monophyletic lineage of about 15 genera and 160 species , Chauveau et al 2012. Cypella Herbert (1826Herbert ( : t. 2637, with 30 species and four subspecies accepted by the World Checklist of Iridaceae (WCI), is one of two largest genera of the tribe in South America , Barker 2014.…”
