BRITISH EOCENE FLORA. 



cones have lost their basal scales, as if they had suffered decay on land or abrasion in 

 rapidly moving streams before reaching salt water/ 



The fossils bear a considerable resemblance to Pitys Haidingeri, pi. xix, ' linger 

 Chloris Protogaea,' p. 73, from Leoben in Styria, and very little doubt can exist as to their 

 identity with Pinus Defrancii,^ Ad. Brongn., from the " Calcaire grossier," of Arcueil, 

 in the Paris Basin. Pinus hordeacea, Rossner, from Tschnernowitz, in Bohemia, is also 

 not dissimilar. 



The nearest existing species seem to be P. laricio, P. pyrenaica, and P. halepensis, 

 Pines belonging essentially to the Mediterranean region. 



P. Dixoni, if all the specimens are correctly placed in the same species, would range 

 from the Bracklesham to high up in the Bembridge Marls, but it is not improbable that 

 a good series of more perfect specimens might lead to the recognition of more than one 

 species.

This Pine is so far only known from very mutilated specimens, and the original 

 example figured in the ' Geology of Sussex ' no longer exists, Dixon's figure does not in 

 all probability exhibit the true apices of the scales, for they are represented merely as 

 bluntly recurved, without umbo, but considerably thickened, forming a type of scale 

 unknown in the genus Pinus. The similarity in the breadth and form of the scales and 

 of the cone generally have induced me to unite with it a specimen in which a few scales 

 are perfect ; they are of somewhat crescentic form, two centimetres broad, transversely 

 keeled, and with small recurved mucronate umbo. 



Mr. Carruthers, in separating it from P. Dixoni, Bow., described it as " ovate (?) or 

 oblong (?). Scales very large, broad, and cuneate ; apex broad, fiat, and with a re- 

 curved edge ; covered part of the scale large, and deeply imbricated." He also suggests 

 that it might be only the upper portion of a very large and long cone, but I scarcely think 

 this can have been the case, and I am inclined to believe that nearly the entire axis is 

 present in the specimen figured in Plate XIII, fig. 9. 



1 Whether the decay is due to such causes, or to the ravages of birds or squirrels, tlie basal scales 

 are the first to suffer.
