20 Arber, Fossil Plants from the Ardzvick Series. 



Ardwick Series. In association with fairly well-preserved 

 stems showing the characteristic leaf bases, numerous 

 young shoots occur, which are densely clothed with leaves. 

 These leafy branches are the plants recorded by Binney 

 as Lycopodites sp. One of the specimens from Ardwick 

 is thus labelled in Binney's hand-writing. Similar 

 specimens from Ardwick are in the Manchester Museum, 

 Owens College.

This species is a very interesting one, and one which 

 is comparatively rare in British rocks. The Ardwick 

 specimen is regarded by Mr. Kidston, to whom I have 

 referred it, as identical with the plant figured by Zeiller as 

 L. dichotomum. Mr. Kidston is not at present quite con- 

 vinced that Zeiller's plant is identical with that first 

 described by Sternberg under the same specific name. 

 The Ardwick species may also be identical with some 

 specimens described in 1885 by Mr. Kidston as L. Peachii, 

 from Falkirk, Stirlingshire, and from the Middle Coal
