The present communication deals with pollen analyses of moss polsters in order to understand the pollen rain from Udhampur District of Jammu and Kashmir, India. The study revealed that the pollen of Pinus sp. (average 46% pollen) dominates the pollen rain, which could be attributed to its high pollen productivity and excellent pollen dispersal efficiency, followed by Cedrus sp., and Podocarpus sp. However, other conifers such as Abies sp., Picea sp., Juniperus sp. and Tsuga sp., as well as the broad-leaved taxa such Alnus sp., Betula sp., Ulmus sp., Quercus sp., Carpinus sp., Corylus sp., Juglans sp., Ilex sp., Mallotus sp., Elaeocarpus sp. and Aesculus sp., were sporadically recorded which could be due to either their poor pollen dispersal efficiency or poor preservation in the substrate. Tubuliflorae, Poaceae, Amaranthaceae, Malvaceae and Cerealia are the other prominent taxa of the pollen rain, revealing their actual composition in the ground vegetation.
