Discussion

Species 7 or 8 (1 in the flora).

Chromosome counts from New Zealand (E. J. Beuzenberg and J. B. Hair 1983; P. J. de Lange et al. 2004) indicate a base number of x = 5 for Glossostigma. An anomalous count (2n = 32) has been reported for G. diandrum (Linnaeus) Kuntze from Bangladesh (see M. O. Rahman 2006).

"broad" is not a number.
