Abstract
THE Gnetales are considered to be the most highly evolved order among the gymnosperms. Tho fossil record of the order is surprisingly poor, and has been reviewed by Wilson1. Some palynologists have, however, reported the occurrence of fossil pollen grains having close resemblance to gnetalean pollen. While analysing some samples from Dharamsala beds (Lower Miocene to Oligocene) of Kangra District, Punjab, we came across some pollen grains which showed a gnetalean affinity.
