On the Trail of Morphological Traits: Morphometry Helps to Clarify Morphological Variation in Section ().

, a large genus of the Iridaceae family, is divided into ten sections and defined by genetic, morphological and phylogenetic traits. The section , though monophyletic, encounters taxonomic hurdles, particularly within the L. and Spreng complexes, resulting in numerous misidentifications.

Cytological and genome size data analyzed in a phylogenetic frame: Evolutionary implications concerning Sisyrinchium taxa (Iridaceae: Iridoideae).

Sisyrinchium is the largest genus of Iridaceae in the Americas and has the greatest amount of cytological data available. This study aimed at investigating how genomes evolved in this genus. Chromosome number, genome size and altitude from species of sect.
