Standard KOH and acetolysis pretreatments (Faegri & Iversen 1989) were used and selected pollen and spore percentage taxa are presented in FIGURE 5 (palynomorph type nomenclature follows Bennett et al.
For pollen analysis a dried sample of 50 mg was treated with 10% HCl, followed by the standard acetolysis of Moore & Webb (1978).
Next, each sample was washed with distilled water, centrifuged and then extraneous organic material was oxidized using the acetolysis process consisting of a mixture of sulfuric acid and acetic anhydride (Erdtman 1960).
The analysis was based on the principle that microscopic elements were concentrated by centrifuging the honey dissolved in water, examining the sediments and evaluating them under the microscope after acetolysis.
Sixty-four samples for pollen and spore analysis were prepared using standard KOH, HF, HCl and acetolysis techniques (Moore et al.
Following acetolysis, the herbarium samples were cleaned and concentrated through sucrose (Chissoe & Skvarla, 1974), made conductive with solutions of osmium and thiocarbohydrazide (Chissoe et al.
