CONTRIBUTIONS TO A CHROMOSOME ATLAS OF THE NEW-ZEALAND FLORA .34. WAHLENBERGIA (CAMPANULACEAE)

Meiotic and mitotic chromosome counts are documented for 16 taxa and o ne putative hybrid of Wahlenbergia in New Zealand. Ten taxa, all those with rhizomatous growth form, have 2n = 4x = 36. Of the remaining gro up, with radicate growth form, five species and one hybrid have 2n = 8 x = 72, and an undescribed species has 2n = 6x = 54. Chromosome counts are also provided for two Wahlenbergia species from Australia with 2n = 4x = 36 and 2n = 6x = 54, one from Japan with 2n = 8x = 72, one fro m New Caledonia with 2n = 8x = 72, and one from West Bengal with 2n = 2x = 18.
