Quick Reference

An extinct plant, the last species referred to its genus and to the family Glossopteridales, which is known from the Trias of India. Glossopteris is characterized by a leaf with a fairly well defined midrib and a reticulate venation. The Permian glacial deposits of S. Africa, Australia, S. America, and Antarctica are succeeded by beds containing a flora very different from that of N. America and Europe. The flora of the south grew in a cold, wet climate, while that of the north existed under warm conditions. Plants with elongate, tongue-shaped leaves dominated the southern flora, of which the genera Glossopteris and Gangamopteris are among the best known. Of these two, the genus Glossopteris gives its name to the flora.
