Descripción
Mimosa debilis Humb. Bonpl. ex Willd. and M. nuda Benth. were grouped in specific and infraspecific complexes. Both taxa showed exomorphological similarities, with conflicts in their taxonomic circumscription and present different ploidy levels. The objective of the present contribution was to analyse chromosome numbers of different populations and to evaluate morphological characters of specimens from Paraguay, Argentina and boundary regions. Chromosome numbers of M. debilis var. debilis (2n=2x=26 and 2n=4x=52) confirmed previous reports, whereas those of M. nuda var. glaberrima (2x=26, 4x=52), M. nuda var. gracilipes (2x=26, 4x=52) and M. nuda var. nuda (4x=52) are presented for the first time. Variation was observed in habit, foliar and floral morphology and was correlated with the chromosome number and the geographical distribution of the taxa. Groups with stable morphological characters and restricted geographic distribution were identified. Also, the results showed a pattern of hybrid swarms and polyploids of different origin that may explain the existence of taxonomic conflicts in the M. debilisM. nuda species complex. On the basis of these results, M. nuda should be included in the synonymy of M. debilis.
