The original of pi. cxiii., fig. i, of Lindley and Hutton, 

 is much less perfect than Williamson's drawing represents 

 it, but the general features are faithfully shown. The 

 specimen has a length of I3"5 cm., the main axis bears 

 several lateral branches given off at an acute angle, clothed 

 with numerous spirally-disposed, angular and strongly- 

 incurved leaves. The form of the leaves is very similar to 

 that of the leaves of the Norfolk Island pine {Araucaria 

 ex eels a R. Br.) 



The original of pi. cxiii., fig. 2, consists of a branch 

 4'8 cm. in length, terminating in an imperfectly preserved 

 cone, which is much less perfect than as represented in 

 the drawing. The cone consists of a central axis, bearing 

 crowded imbricated scales with broadly acuminate 

 distal ends. The leaves borne on the branch agree 

 with those on the larger specimen (pi. xciii., fig. i), and 

 resemble the thick and curved leaves oi Araucaria- excclsa.
