THE CARBONIFEROUS FLORA OF 

 YORKSHIRE. 



FIRST REPORT 



Ox HEHALF OK THE YORKSHIRE FOSSII. FlOKA CoMMITTKE. 



ROBERT KIDSTON, F.R.S.E., F.G.S. 



This Committee was appointed at the Annual Meeting held 

 at Malton, in March, 1888. but before any Report could be 

 prepared, some time had necessarily to elapse for the collection 

 and examination of specimens. In the case of the specimens 

 collected prior to the formation of the committee, the majority 

 of them are without any note as to the horizon from which 

 they were derived, and even the locality, when stated at all, is 

 in most cases very vague. Unfortunately these remarks apply 

 to almost all the specimens in our Museums, hence the working 

 out of the horizontal and vertical distribution of the Carbonifer- 

 ous Flora can only be done satisfactorily from new material. 



This has delayed the first report, and though it contains 

 the record of over one hundred species it must be regarded as 

 only of a provisional nature. Continued research will doubt- 

 less much increase the number of species and also show a wider 

 distribution of those already known. From want of coUectois 

 there arc practically no records from many parts of the coal 

 field, not that fossil plants do not occur in those areas, but 

 simply that they have not been collected. 'l"he committee there- 

 fore earnestly request members who either possess fossil plants 

 or know of any collections, to communicate with the secretary.
