Cytology The difference between this and other studies of hybridization involving Hawaiian taxa is that in these instances hybrids can be identified with certainty through an analysis of chromosome pairing during meiosis in floral buds. In each of these cases the parents are differentiated chromosomally and these differences can be positively detected at meiosis. In every hybrid except D. scabra x g. plantaginea the diploid chromosome number is 2n 27, indicating in these instances that one parent furnished 13 chromosomes and the other parent furnished 14. In all cases the chromosome numbers of the parents are consistent with this argument (cf. Carr, 1978). Although D. plantaginea and - D. scabra both have 14 pairs of chromosomes, hyErids between the two can be readily recognized at meiosis by virtue of the fact that their genomes are differentiated by two reciprocal chromosome translocations resulting in the appearance of two chains of 4 chromosomes each (cf. Table 1). These meiotic perturbations result in the inviability of some of the gametes formed. This depression of fertility can be assessed by the staining reaction of pollen grains in certain dyes like cotton blue. Genetic differentiation between parents can also cause low viability and thus low pollen stainability in hybrid plants. Pollen stainability in the hybrids discussed herein ranges from 6 to 86% (Table 1). Conclusion In spite of the spectacular morphological and ecological diversity exhibited by these genera, the occurrence of many intergeneric, intersubgeneric, and interspecific hybrid combi- nations under field conditions attests to the fact that they form a thoroughly natural, genetically cohesive group that has in all probability resulted from rapid evolutionary differentiation of a single colonizing progenitor. Collectively, these plants consti- tute what may be considered an unparalleled example of adaptive radiation and as such are exceedingly interesting to students of evolutionary phenomena.
