"THE CARBONIFEROUS FLORA OF 
YORKSHIRE. 
SECOND REPORT 
ON BEHALF OF THE YORKSHIRE FossiL FLORA COMMITTER, 
FOR 1890. 
ROBERT RIDSTON, FRSE, DES 
SINCE giving in the last Report, at the Hull Meeting, in 
November, 1889, I have to note the occurrence of ten species 
not previously known to occur in Yorkshire, and of these some 
are new to Britain. ‘They have all been collected by Mr. W. 
Hemingway, to whom, for his continued successful labours, the 
Committee owe so much for their knowledge of the Yorkshire 
Carboniferous Flora. In addition to the records of the species 
new to Yorkshire, Mr. Hemingway has added many new 
localities for those already recorded. 
The Committee are also indebted to Mr. James Spencer, 
Halifax, whose collection has afforded several new /oca/ifies for 
species included in the first Report. 
In addition to the records in this Report, there are still 
some specimens awaiting further examination which, owing to 
several circumstances, must be held over. In some cases these 
species have been excluded meanwhile, awaiting the oppor- 
tunity of comparing them with authentic specimens of the 
species to which they are believed to belong. 
For the assistance given by Mr. Spencer and Mr. Heming- 
way the Committee return their hearty thanks. 
The Committee again take this opportunity of appealing 
to Yorkshire Geologists for assistance in carrying on their 
investigations. —
