Abstract:
The frond structure of Protoblechnum and the other similar plants is examined. These plants are like the neuropterids of the Late Palaeozoic Era, with forked or unforked rachides, whose fronds are simple pinnate or pinnately compound leaf and unequally or equally pinnate fronds. Based on the new materials of the bipinnatifid fronds of Protoblechnum contractum (Gu & Zhi) from Henan in China, it may be seen that other species of Protoblechnum besides Protoblechnum wongii Halle may also be bipinnatifid fronds. The discovery provides important materials for making a clear distinction between Protoblechnum and similar plants.
