Plants of the family Iridaceae are well represented in the grassland vegetation of southern Brazil, occurring in the Pampa and Atlantic Forest biomes. Nevertheless, little is known about the taxonomy and evolution of Iridaceae species in southern Brazil. The main goal of this review is to compile published information about South American Iridaceae, and to discuss the evolution and genetic diversity of the family presenting our own research data in the light of the published literature.

Genetic and ecological niche modeling of Calydorea crocoides (Iridaceae): an endemic species of Subtropical Highland Grasslands

The data showed high levels of polymorphism maintained in this species that could ensure conservationist practices in which the main goal is to preserve the evolutionary potential of the species through the maintenance of genetic diversity.

Multidisciplinary approaches for species delimitation in Sisyrinchium (Iridaceae).

This study evidenced that the two morphological categories of S. sellowianum correspond to distinct and reproductively isolated species and that floral traits reflect their breeding system, with allogamous plants in MC-I and autogamous inMC-II.

The genus Crocus, series Crocus (Iridaceae) in Turkey and 2 East Aegean islands: a genetic approach

AFLP analysis was used to identify a high level of polymorphism among Crocus specimens collected from various locations in Turkey and Greece, and the structural analysis yielded 2 reconstructed populations.

Evolutionary trends in Iridaceae: new cytogenetic findings from the New World

Although no clear difference was observed among the genome sizes of Tigridieae and Trimezieae, an important distinction was observed between these two tribes and Sisyrinchieae, with the latter possessing the smallest genome sizes in Iridoideae.

Les aspects de la variabilité génétique et cytogénétique, et de la biologie reproductive chez Sisyrinchium micranthum Cav. (Iridaceae) dans le sud du Brésil

The genetic variability of S. micranthum was demonstrated in this study in terms of genetic divergence between populations and variation in rDNA loci number possibly reflect the complex relationship between polyploidy and reproductive aspects of the species.

Molecular Characterization of the Indigenous Stingless Bees (Tetragonula spp. Complex) Using ISSR Marker from Southern Peninsular India

Potential exploitation of hyper-variable ISSR marker turned out fairly as a promising technique for finding valid polymorphisms and infers relevant variations in Tetragonula species complexes from natural and semi-urban habitats, and enhances understanding of the genetic status of the indigenous species from the country.


A review of the use of molecular markers and cytogenetic data, applied to the detection of plant biodiversity, and a few examples of this kind are mentioned.

First report of a newly naturalized Sisyrinchium micranthum and a taxonomic revision of Sisyrinchium rosulatum in Korea

Sisyrinchium micranthum Cav., a newly naturalized species, was found in Seogwipo, Jeju-do. This species is native to Central and South America and is reported as a widely invasive species around the

The specialization–generalization continuum in oil-bee pollination systems: a case study of six Brazilian species of Tigridieae (Iridaceae)

The results strongly suggest that the studied species are distributed along a specialization–generalization continuum, and provide a significant contribution towards a better understanding of reproductive biology and plant–pollinator interactions between Iridaceae and oil-collecting bees.

Acta Botanica Brasilica

This review proposes to establish a consistent nomenclatural classification in the field of angiosperms reproductive biology with consistent and well-defined applications of relevant terminologies to facilitate communication among researchers.



Population genetic structure of Sisyrinchium micranthum Cav. (Iridaceae) in Itapuã State Park, Southern Brazil

Molecular analysis showed that the populations are highly structured with low gene flow among them, and population genetics in relation to cytogenetic data provided new insights regarding the genetic diversification and mating system of S. micranthum.

A new species, Herbertia crosae (Iridaceae), from Uruguay

A key to the species of the genus is provided in which five species are now recognized and the new species resembles Herbertia lahue but can be easily distinguished by the narrower leaves, slender habit, and smaller pale lilac flowers.

Effects of grazing disturbance on the reproduction of a perennial herb, Cypellaherbertii (Lindl.) Herb. (Iridaceae)

It is concluded that grazing impact on pollinators together with C. herbertii’s high dependence on pollinator should be considered when assessing the risk of extinction of this species.

Phylogenetic analysis ofIridaceae with parsimony and distance methods using the plastid generps4

A molecular phylogeny of the familyIridaceae based on the plastid generps4 was obtained using both parsimony and distance methods, and shows that the family is monophyletic, and that Isophysis is likely to be the earliest emerging genus.

Genome Size Variation in Sisyrinchium L. (Iridaceae) and Its Relationship to Phenotype and Habitat

The increase in genome size among diploid species in the Southern Hemisphere showed a positive correlation with seed weight but was not correlated with epidermal cell volume, which is suggested to be related to onset of growth, length of growing period, and reproductive strategies.

Evolution of oil-producing trichomes in Sisyrinchium (Iridaceae): insights from the first comprehensive phylogenetic analysis of the genus.

The distribution of oil-flower species across the phylogenetic trees suggests that oil-producing trichomes may have played a key role in the diversification of the genus, a hypothesis that requires future testing.

High levels of genetic diversity in populations of Iris aphylla L. (Iridaceae), an endangered species in Poland

Although sexual reproduction and gene flow between populations of I. aphylla were very limited, they preserved high levels of genetic diversity, indicating that genetic diversity was independent of population size.

An Anatomical and Chromosomal Investigation of Sisyrinchium and Allied Genera

Leaf anatomy and chromosome numbers were examined for a wide range of species of Sisyrinchium and three small allied genera, Phaiophleps, Chamelum, and Solenomelus, in terms of their taxonomic

Cytological studies in South AmericanIridaceae

Although the South American Iridaceae are cytologically diverse, three tribes are distinguishable on the basis of karyotype morphology, and changes in chromosome size within genera may suggest fluctuations in their DNA amount with latitude and altitude.
