SCHIZONECEA. O 



Distribution. — Schizoneura appears first in the Talchir Beds of 

 India (Upper Carboniferous), and occurs also in the Damuda Series 

 (Permian). It is also known from South Africa in beds of Pcrmo- 

 Carboniferous age, and in New South Wales near the top of the 

 Permo-Carboniferous Series. The genus, however, reaches its 

 maximum distribution in beds of Triasso-Bhsetic age. In India, 

 Panchet Series; 1 in South Africa, Stormberg Beds; 2 from the 

 Lower Trias of the Vosges, 3 the Upper Trias of Germany; 4 the 

 Bhaetic of Sweden, Germany, Persia, Tonquin, 5 China, 6 and 

 elsewhere.

Stems articulated, branched. Bidges and grooves of the external 

 casts of stems and especially of branches, not very prominent. 

 Oval scars of the vascular bundles of the leaf-sheath are 

 sometimes seen at the node. Pith (?)-casts more coarsely ridged. 

 Leaf-sheaths large, usually 9 cm. long, but sometimes shorter or 

 even longer, usually split into two oblong or lanceolate multi- 

 nerved lobes. Each lobe may in turn be divided to the base into 

 12 to 20 linear uninerved segments. Where the lobes are
