Gymnosperm are the plants of the remarkable importance, they Have the long evolutionary history, form the evolution point of view these groups form the importance’s in the plant kingdom, in this series these plant groups are adapted for the best xeric conditions, the evolution of the vascular system as well as other parts of the plants can be best seen in that group. The evolution of all the organs form roots to the shoots is also the another point of interest. We can observe the cladistics as well as the punctuated equilibrium in the gymnosperms. Mesozoic era was the time of the basic flourish of the gymnosperm in the geological time scale, due to rapid evolutionary changes of the nature and the geological revolutions these groups are very relicts. Well now a day only a belt of the distribution of the gymnosperms can be seen all over the world, some of the northern hemisphere are the point of the distribution of the gymnosperms, in India some mountainous places are the point of the distribution for the gymnosperms. Sustainable utilization and conservation of the gymnosperm is the essential features for the propagation of these plants groups.
