except that the transverse walls remain unthickened. Very large 

 cells, with rather conspicuous nuclei, occur in the apical region, 

 but disappear on further development (fig. 12). 



The branching, as often obtains in the liverworts, is endogenous. 

 At an early stage the rudiment is covered by the two outer layers of 

 stem-cells, which it subsequently breaks through (fig. 13). 



This work has been done at the Eoyal College of Science, under 

 the direction of Prof. Farmer, to whom I am indebted for the 

 material, and for advice and assistance given throughout its 



PS. — Since the above work was completed, a paper ("Arche- 

 goniatenstudien ") has been published by Prof. Goebel in Flora for 

 December last, in which the structure of the apex and the 

 development of the auricle are described in another species (P. 

 conchafolium, and his results agree in the main with those given 

 above. The remaining points, however, are not covered by his 



Explanation of Plate 339.— Fig. 1. Small shoot, seen dorsally; nat.size.
