Ginkgo digitata (Brongn.) forma Hutton. 
The only example of the genus Ginkgo hitherto recorded from the Kimeridgian 
strata of Scotland is an imperfect leaf-impression referred to Huer’s species G'. sibirica.t

is a fairly good example of a Ginkgo leaf with broad cuneate segments, of the form 
frequently spoken of as Ginkgo Huttoni (Sternb.). Through the courtesy of Professor - 
NatHorst a drawing was made of the specimen in the Stockholm museum: this

CoNCLUSION. 
The fossils described in this paper, though unfortunately for the most part frag- 
mentary and imperfectly preserved, enable us to extend the list of species of Scottish 
Jurassic plants. There can be no doubt that further search both among the petrified 
blocks on the beach at Helmsdale and on the shores of Kathie Bay, will lead to the 
discovery of additional information as to the structure of Kimeridgian plants, and one 
of our aims in writing these pages is to stimulate further research into the composition 
of a comparatively rich and by no means exhausted flora. 
The list of Jurassic plants recorded from Scotland, published by one of us in a 
paper communicated to the Royal Society of Edinburgh in 1910,{ may be supplemented 
by the following species :—
