The species was introduced to Brazil about 60 years ago and now the country is the world?s biggest producer. Even though the fruits of acerola have high commercial value, as they are an important source of the natural vitamin C, very little chromosome information is available for this species. Previous studies showed that most Malpighia species are diploids, including M. emarginata with 2n = 20. In the present paper, the chromosome number of acerola was confirmed, and for the first time, its karyotype was described, providing the identification of the homologues for the ideogram construction. The acerola chromosomes are small (1.71 to 2.56 ?m) and metacentric with the exception of chromosome 2 that was classified as submetacentric. In addition, it is recommended a protocol to produce rooted-plantlets in vitro for mitotic studies that could be also used for micropropagation of acerola.  achromosomes  aAcerola  aCytology  aIn vitro culture establishment  aWest Indian cherry1 aOLIVEIRA, C.
