NOTES ON THE JURASSIC FLORA OF 

 CLEVELAND. 



By Rev. George J. Lane, f.g.s. 



In the month of September, 1908, the Yorkshire Geologists 

 visited the Marske Quarries. Many specimens of plants 

 were obtained on that occasion, and the task of further 

 investigation was urged on Mr. Saunders and myself. To 

 this interesting work we addressed ourselves with vigour. 

 A list of our finds was published in the Naturalist for March, 

 1909, and further genera and species in my possession will 

 appear in a later issue, as I have opportunity. Members 

 of our Field Club are acquainted with the geological horizon 

 of the Marske Quarry, so that any general description is 

 superfluous and unnecessary. Difficult specimens of the 

 plants obtained have been submitted to Professor Seward 

 for examination. I also had the great honour of a visit 

 from Prof. Nathorst, of Stockholm, who determined all the 

 plants in my possession, and encouraged me in the Avork. 

 As stated in a previous number of the Proceedings of our. 

 Club, Mr. Elgee collaborated with me in determining the 

 plants, and it is gratifying to him and myself to know that 

 with few exceptions, Prof. Nathorst confirmed our results. 

 As stated in my article in the " Naturalist," we, as a Club, 

 acknowledge our indebtedness to the Rev. J. Hawell, who 

 did some excellent pioneer work in the Marske Quarry, 

 which resulted in the identification of seventeen species, 

 finding for the first time in England a Dictyozamites, which 

 was named after him Dictyozamites Hawelli. 



The following list has been found by Mr. Saunders and 

 myself : — 



I. EQUISETALES— 



Equisetites columnaris (Brongn). 

 „ beani (Bunb.) ?
