Erratum to: Genomic DNA extraction from herbarium samples of Cunila D. Royen ex L. (Lamiaceae) and Polygala L. (Polygalaceae)

Herbarium collections represent an important source of rare and foreigner species being an alternative for molecular studies. The present study tested a simple DNA extraction method from herbarium tissues of several ages, as well different PCR methods. The DNA degradation appears to be more related to the condition of exicates than the year in which it was dried.
