Abstract
A critical insight into the meiotic profile and behaviour of Balsaminaceae has been attempted. Fairly high recombination index, incapacity for outbreeding, the patent bivalent symmetry, endemic habit, circumscribed ecological location in marshy niches-all these would appear to stamp out the monotypic Hydrocera as a taxon that has reached evolutionary cul-de-sac.
The four varieties of Impatiens balsamina have registered very intimate affiliation as reflected in their meiotic traits.
Cytogenetical affinity between Impatiens latifolia and I. leschenaultii with each other is far more intimate than with the rest of the genus. I. clavicornu, among the different species of Impatiens, is unique in its meiotic profile and behaviour and affords a glaring example of the profound impact of karyogenetic factors on the phenotypes.
