NO AIRBORNE POLLEN WITHIN TROPICAL RAIN-FORESTS

An attempt was made to collect air transported pollen, using mosses as natural pollen traps, in 2 localities of tropical rain forest namely, in mountain forest in Sabah and in lowland forest in Sarawak, Borneo. No airborne pollen was collected. The observation was confirmed by ex posing adhesive-coated slides as pollen traps, using the methodes of B oehm and Leuschner. Moss spores were abundant. These findings agree wi th the well known fact that tropical rain forests are both structurall y and floristically unsuitable for anemophily (wind pollination).
