title: Atomospheric pollen counts in Brasilia, Brazil.
abstract: Daily pollen counts were made in Brasília DF, Brazil, from February 9, 1973 to February 9, 1974. Just one pollen season was perfectly delineated: a grass season. Two weeds, Smilax and Aristolochia, showed some regularity, with a few number of pollen granules. Tree pollens belonging to the Rosaceae family presented a similar behaviour.
