BRACnVPHYLLUil. 297 



Brachyphylluni, and as indicating the very close resemblance 

 between the Yorkshire plant and Cheirolepis Muenstcri, Schcnk. 



The vegetative shoots branch at a more actite angle than in 

 Brachyphylluni. The leaves are crowded, spirally dispose:!, fairly 

 stout, and falcate in form. 



The fragments of this species resemble in habit Sequoia yigantea, 

 Lindl. & Gord., and may be compared also with Araucaria Balansce, 

 Brongn. & Gris., and Bacrydium Franldinii, Hook., but the material 

 is too meagre and ill preserved to admit of a full diagnosis or of 

 a satisfactory comparison with recent Conifers. 



40,570. Several fragments similar to the Scarborough example 

 (Fig. 53a) ; imperfect and fragmentary. 



Genus BRACHYPHYLLUM, Brongniart. 



[Tableau, p. 69, 1819.] 



The genus Brachyphylluni, 1 like many other fossil Conifers, 

 cannot be safely assigned to any definite position among recent 

 genera. The habit of the branches and the form of the leaves 

 favour a comparison with some species of the Tasmanian genus 

 A rthrotaxis : but we are not in a position to speak with confidence 

 as to affinities of this common Mesozoic genus.
