    Análisis cariológico de ocho especies de encinos (Quercus, Fagaceae) en México
    (Spanish National Research Council, 2006) Saúl Flores-Maya; Ivonne Flores-Moreno; Silvia Romero-Rangel; Carlos Rojas-Zenteno; Liliana Elizabeth Rubio-Licona
    Karyotype analyses of eight species of the Quercus genus were performed and are reported here. Five species (Q. candicans, Q. crassifolia, Q. elliptica, Q. hintonii and Q. urbanii) belong to the Lobatae section and three (Q. frutex, Q. obtusata and Q. rugosa) to the Quercus section. This is the first report of the chromosome numbers of all of them except Q. rugosa, and demonstrate that they are diploid (2n = 2x = 24) and the karyotypes are moderately asymmetrical.
