Hypnodendron comatum in section Comosa is listributed in N e w Zealand, with a doubtful rec- )rd from Norfolk Island (Touw, 1971). The five populations examined (Table I, Appendix I) all lad the chromosome number n = 4 (Fig. 54). The bivalents were larger than those in other taxa with four chromosomes. The large bivalent (Figs. 14, 57) is probably not fuUy contracted. There is I larger chromosome visible at both anaphase I Fig. 55) and metaphase II (Fig. 56).
