Abstract

Gymnosperm are the plants of the always of the great economic and the evolutionary values. They have the abundant empire in the Mesozoic era; the conservation of the nucleic acid is the significant step in the tracing the evolution of the plants in the geological history of these magnificent plants. The cycadales are considered as the living fossils, only 11 genera of the cycadales have been reported from all over the world. The whole group is represented by the genera of the conifers which are well distributed in the in India and the other part of the world. They are utilised for the fulfilment of the many kinds of the needs of the human beings. In this review article we are working on some of the aspects of the one of the conifer genus entitled as the Ketelaleria. This is the genus which has a very narrow distribution in the current era, however the Long history of the plants can be seen in the late Triassic era. The genus is well distributed in the china and the Vietnam. In India however, few members can be seen but as far as the endemism is concerned these plants are well distributed in the central china. conservation of the plants is necessary for the saving of the belt in the world since the plants is important from economically and the evolutionary point of view.
