This paper presents first cytogenetical analysis of a monotypic genus, Zanonia indica (Cucurbitaceae). The diploid chromosome number was 2n = 2x = 30. Male meiosis was normal and revealed 15 bivalents at diakinesis. Karyotype was symmetrical (Stebbins’s 4a category). All chromosomes possessed median centromere. Chromosome length ranged from 1.10 ± 0.14 µm to 1.98 ± 0.33 µm. Mean chromosome length (MCL) was 1.47 ± 0.24 µm. Pollen grains were tricolporate and prolate with P/E ratio 1.49.
