The ■writings of Morris,' Carruthers,'' Starkie Gardner,' and 

 others contain scattered references to descriptions of Lower Oolite 

 plants ; several species of the British Jurassic flora are dealt with 

 also by Saporta ' ia his Monograph on the plants of this period. 



The most important of the more modem contributions to our 



knowledge of the Jurassic plants of England is unfortunately 



written in the Swedish language, and is not accompanied by any 



illustrations. In 1880 Nathorst* published a series of notes on his 



visits to various English Museums, together with observations 



made in the field at some of the principal plant localities on the 



Yorkshire coast. The same author discovered a new plant-bed 



between White Nab and Scarborough, which enabled him to add 



some new species to the Lower Oolite flora. Nathorst's notes 



have proved of considerable value in the examination of the 



Yorkshire plants, and his opinions on the several species are 



frequently referred to in the descriptive part of this Catalogue. 



The following new species are mentioned or briefly described, 



but in some cases I have been led to identify them with species 



previously recorded. Whether or not Nathorst's supposed new 



species should be retained, there can be no question as to the 



great value of his critical notes.
