CORREA, Maria Goreti Senna et al. Chromosomal characterization of Anthurium gaudichaudianum (Araceae), a native Brazilian species. Rev. bras. Bot. [online]. 2010, vol.33, n.4, pp.705-710. ISSN 0100-8404.  http://dx.doi.org/10.1590/S0100-84042010000400017.

The karyotype of Anthurium gaudichaudianum Kunth, a species belonging to the Araceae family, is described for the first time. The species is native to Brazil, occurring from the state of Rio Grande do Sul to the state of São Paulo, and the specimens examined were collected from Brazilian Atlantic Forest, in the woods of the municipalities of Torres and Peruíbe, located in the states of Rio Grande do Sul, and São Paulo, Brazil, respectively. Anthurium gaudichaudianum has 2n = 2x = 30 and its karyotype is formed by three pairs of metacentric chromosomes, nine pairs of submetacentric chromosomes and three pairs of acrocentric chromosomes, one of them with satellites (6 m + 18 sm + 6 a). The size of the chromosomes vary from nearly 6.0 to 2.8 μm. The complement of 30 chromosomes for A. gaudichaudianum found in our study is in accordance with the findings of 2n number for most of species in this large genus.
