380 MR ROBERT KIDSTON ON THE FOSSIL FLORA OF THE 



once the H. pulckerrima of Corda and the fruit of Pec. Miltoni. The fossil 

 occurs as a dark brown impression of the lower surface of the frond on a 

 yellow-brown matrix. On the left of the rachis, of which only a small portion 

 is shown, are the remains of 7 pinnae. The 3 lower ones are imperfect, but the 

 4 upper show their complete length. The pinnules at the base of the pinnae 

 are contiguous and oblong, with blunt apices; the upper pinnules are confluent. 

 The whole of the surface of the pinnules is thickly covered with stellate groups 

 of sporangia, hence the veins are only seen at a few points of the specimen, and 

 even then indistinctly. The sporangia are oval, and arranged in stellate groups 

 of 3-6 sporangia, though 4 is the common number in each little star. The 

 central point of attachment of the groups of sporangia is situated midway 

 between the central vein and the margin of the pinnule, which latter bears a 

 greater or less number of sori. In this example the pinnules near the apex of 

 the pinnae bear very few sori ; those about the centre bear three on each side of 

 the midrib, whilst the lowest pinnules bear 5 or 6 sori on each side of the main 

 nerve. The little stellate groups of sporangia measure in their greatest dia- 

 meter 1 mm. to 15 mm., the individual sporangia ranging from *5 to 75 mm. 

 This specimen was associated with barren examples of Pecopteris Miltoni, 

 Artis, sp.
