Abstract

The chromosome numbers of the two species of Byblis and their karyotypes are recorded, and compared here for the first time. The karyotype formulas for both species are as follows: Byblis gigantea Lindl.: K (2n = 14) = 2sat Aot + 2Bsm + 2Cm + 4D1ot + 2D2sm + 2Em; B. liniflora Salisb.: K (2n = 24) = 2A1sm + 2sat A2ot + 2Bsm + 2satCot + 2Dot + 2Eot + 2F1sm + 2sat F2ot + 4Got + 4Hot. Byblis is in an aneuploid series, and the basic chromosome numbers are X = 7 for B. gigantea and X = 12 for B. liniflora.
