The seed, which is 5 cm. long and 2 cm. broad, gradually contracts into a micropylar 

 beak, which is about 075 cm. long but may not be quite complete.

 described above. To the side of the cushion which bears the seed is attached a foliage 

 pinnule of the ordinary type. The specimen is seen enlarged 3 times at text-fig. 5. 

 Neuropteris heterophylla is very common and widely distributed on the coal field.
