74 OOLITIC SERIES. 



A complete classification of the Oolitic series should include the- 

 various local variations in the nature of the sediments to which 

 special names have been applied. For a more detailed list of the 

 subdivisions of the Oolitic rocks, as founded on the development of 

 the series in different parts of the country, reference should be 

 made to Mr. H. B. Woodward's standard work on the Lower 

 Oolitic rocks of Britain,' and to the memoir by the same author- 

 on the Middle and Upper Oolitic rooks of England (Yorkshire 

 excepted).* 



The British Museum collections include fossil plants from several 

 of the above groups ; in most cases the specimens from any one 

 area or sub-stage represent mere waifs and strays of the floras, but 

 the Stonesfield Slate (Bathonian) has afforded a comparatively rich 

 collection. In the following pages I have arranged the species 

 botanically, mentioning in each case the locality and horizon from 

 which they have been obtained. The list of plants given in the 

 concluding section serves to indicate the species described from the 

 various sub-stages of the Oolitic rocks. 



The Geological Survey memoir on the Jurassic rocks of Britain 

 (vol. iv.) by Mr. H. B. Woodward' contains several references 

 to the occurrence of plants in the Lower Oolitic rocks in other 

 parts of England than Yorkshire. Yol. v.* of the series of 

 Jurassic memoirs by the same author affords valuable information 

 as to the plant-bearing rocks of the Middle and Upper OoUtic- 

 strata ; the Yorkshire area is dealt with in a separate volume by 

 Mr. Eox-Strangways.' 



Several Oolitic plants are figured by Lindley & Hutton in their 

 Fossil Flora;" these are given in the following Ust, with the 

 addition of the names employed for their species in the present 

 volume.
