158 DESCRIPTIVE CATALOGUE 



lateral branches covered with well-marked elongated bases of 

 the scale-leaves, in the axil of which are borne the short shoots 

 with long needle-like leaves. Cones oblong in form, with broad 

 scales similar to those of the Strobus section of the recent genus 

 Pinus, or those of Picea and Abies." 



HORIZON. Type is Wealden ; the described specimen, Kentish 

 Rag, Lower Greensand. 



LOCALITY. For type, Ecclesbourne ; described specimen, 

 Maidstoue. 



TYPE. Several twigs, nos. V. 2160, V. 2'2.V>, V. 121 16 [no 

 definite type-specimen is chosen by Seward] ; British Museum 

 (Nat. Hist.). 



The specimen does not show anything but the vegetative twig 

 and leaf bases, and cannot form the basis for any change in the 

 diagnosis of the form with which it is only uncertainly associated. 

 So ward's type-specimens, however, seem to me much more like 

 Larix than the other genera he mentions. 



The association of this Lower Greensand specimen, of which 

 the fructification is unknown, with Reward's type depends 

 entirely on vegetative similarity and is therefore most uncertain. 

 Vegetatively our specimen agrees perfectly with the Wealden 

 form, however, and it would not be justifiable to make it the 

 basis of a new determination. Several American Lower Creta- 

 ceous species may be compared with it (see Berry, 1911, p. 404). 



41408. A twig 12 cm. long, tapering from 1 cm. to *5 cm. in 

 diameter, bearing the bases of three short shoots. The 

 whole surface is covered, as in A. Solmni, by the 

 rhomboidal scars of the decurrent leaf-cushions. 

 Iguanodon Quarry, Maidstone. Mantell Coll. 



Abietites sp. 



Foliage twigs arc very rare in the British Lower Greensand, 

 so that reference should be made to the small piece of twig from 

 the Iguanodon Quarry near Maidstone, shown in text-fig. 4.">. 

 Its specific determination cannot be attempted, but it recalls 

 several already - described fossils, particularly PagiophyUum 

 crassifolium as recorded from the British Wealden by Seward 

 (1895, p. 212), and also parts of his IS phenol epidium Kurrianum 

 (p. 200) of the same age. As this fragment cannot be definitely
