Abstract
Documented chromosome numbers are reported for 33 species, 7 subspecies, 9 varieties, 2 forma, 2 hybrids, and 14 taxa of uncertain rank from 21 families ofangiosperms. Thirty‐eight of these are for previously uncounted taxa and hybrids. The majority of the counts are for nationally uncommon and threatened, or newly described plants. In the majority of genera the numbers follow established patterns but new examples of polyploid series have been found in New Zealand species of Crassula and Gratiola.
