| Abstract: | The atmospheric pollen of Durban has been monitored since 1989 using a Burkard sampler. Data are presented here for the three-year period ending in 1991. The results do not reflect the indigenous sub-tropical vegetation of the area, but rather exotic elements that are either naturalised (Morus) or cultivated (Cannabis and Poaceae). The only indigenous pollen that was recorded in any number was that of the lawn grass Cynodon dactylodon and the tree Celtis africana. However, these two plant types are found country-wide, and are not restricted to sub-tropical regions. All major pollen types recorded have been implicated as allergens. |
