Chromosome studies in southern species of Mimosa (Fabaceae, Mimosoideae) and their taxonomic and evolutionary inferences
(2014-05)In this work, chromosome numbers and karyotype parameters of 36 taxa of the genus Mimosa were studied, especially from the southern South America center of diversification. Results support that x = 13 is the basic chromosome ... -
Cytogeography and morphological characterisation of a taxonomic, polyploid complex of Mimosa (Leguminosae) from subtropical South America
(CSIRO Publishing, 2018)Mimosa subseries Dolentes Barneby and Brevipedes Barneby are ecologically and morphologically high-diversified infrageneric taxa of this genus in southern South America. We performed a cytogenetical and morphological ... -
Increasing reports in Mimosa (Mimosoideae, Leguminosae) for the Brazilian Flora
(Sociedad Argentina de Botánica, 2015-06)Five species of Mimosa for the Brazilian Flora are reported: M. strigillosa, M. leimonias, M. petraea, M. oligophylla, and M. barnebiana. The three first ones are registered from Mato Grosso do Sul, while the remainder are ... -
Karyotype studies in Mimosa (Mimosoideae, Leguminosae) from Southern South America and ecological and taxonomic relationships
(Taylor & Francis, 2011)In this work we studied the chromosome number and karyotype formula of seven species of Mimosa L. (Mimosoideae, Leguminosae). The chromosome number 2n = 2x = 26 for M. detinens Benth., M. hex- andra M. Micheli, M. ostenii ... -
Leaflet trichome micromorphology in the Dolentes-Brevipedes taxonomic complex (Mimosa L., Mimosoideae)
(Tubitak Scientific & Technical Research Council, Turquía, 2016)We studied leaflets of 18 taxa of the genus Mimosa, specifically the Dolentes-Brevipedes taxonomic complex, focusing on micromorphology, type, shape, and density of trichomes. Within the nonglandular trichomes we described ... -
