AIRSPORA OF DURBAN - A SUBTROPICAL, COASTAL SOUTH-AFRICAN CITY .1. POLLEN COMPONENT

The atmospheric pollen of Durban has been monitored since 1989 using a Burkard sampler. Data are presented here for the three-year period en ding in 1991. The results do not reflect the indigenous sub-tropical v egetation of the area, but rather exotic elements that are either natu ralised (Morus) or cultivated (Cannabis and Poaceae). The only indigen ous pollen that was recorded in any number was that of the lawn grass Cynodon dactylodon and the tree Celtis africana. However, these two pl ant types are found country-wide, and are not restricted to sub-tropic al regions. All major pollen types recorded have been implicated as al lergens.
