STRUCTURE AND AFFINITIES OF LEPIDOSTROBI. 



accompanying wood-cut of the cones of the L. Magellanicum will show. 



Fig. 4. 



The internal structure, form of the sporan 

 gium, the length of the apices of the scales, 

 and breadth of the cones, are very nearly 

 alike in all the specimens. To this L. 

 ornatus (Brongniart's Figs. 1, 2, and 4 

 of vol. ii., Tab. 23), should, possibly, be 

 referred. 



The beautiful little nut, of which a 

 wood-cut is added, * is most probably a 

 sporangium, belonging to this cone of Lepi- 

 dodendron elegans ; though differing in 

 shape, its sculpturing corresponds with that 

 of sporangium, removed and restored from 

 Lepidostrobus, Plate 4, fig. 5. 



The young state of this species is the 

 very elegant specimen contained in a no- 

 dule of clay-iron-stone, figured at Plate 7. 

 Besides the more conical and shorter form 

 of the cones, they are distinctly attenuated 

 to the apex, as if hardly matured. The 

 apices of the scales, too, do not appear to 

 be produced downwards to the degree of 

 those of the former species.
