4 Butterworth, Fossil Seeds of Lagenostoma. 



fellow-workers have fortunately picked up parts of the 

 same block in which they have each met with one seed. 

 The whole of these seeds have been found at one pit 

 which has just been abandoned owing to the nodules in 

 which the seeds and plants are found taking the place 

 of the coal. 



Description of figures in Plate 8. 



Fig. i is a slightly tangential section of Lagenostoma. On 

 the upper side, the section is cut through the centre 

 of a lobe, and shows the hairs springing from it. 

 On the lower side, the section is cut through the 

 space between two lobes, and therefore shows few 

 hairs. 



Fig. 2 is an oblique section of another Lagenostoma. In it, 

 the seed appears to have a continuous zone of hairs 

 all round, but they spring only from about the 

 crown of each lobe. The cavity passing down 

 the centre of each lobe is shown at (A).
