摘要: In this paper cytogenetic studies on 64 specimens from 20 Iberian populations ofCarex laevigata (Cyperaceae) are presented. Chromosome behaviour in meiosis suggests that the different chromosome numbers obtained (ranging 2n = 69 to 80) were distributed according an increasing geographic gradient of fission along North → South direction. Four relatively stable areas also delimited displayed by species, i.e. c. 72, 74, 76, and 78. The meiotic ×deserta (C. ×C. binervis) was studied.
