Late Palaeozoic Plant-Geography of the Peri gondwana and Evolution of the Kashmir Basin

A typical Gondwanan Flora comprising species of Trizygia, Glossopteris, Vertebraria, etc. is known from the Kashmir Basin. At certain levels, however, the flora contains some exotic elements, such as Lobatannularia, Sphenophyllum, Kashmiropteris (Protoblechnum/Comsopteris) and Rhipidopsis. All these elements are important constituents of the Cathaysian Flora. In southern Xizang, too, a plant bearing horizon contains elements of both Gondwanan and Cathaysian floras.
