R. H. CAMBAGE. 



The same feature was noticed on the fourth and fifth 

 leaves of separate seedlings of A. spectabilis, but here the 

 lower pinna was 1 mm. below the terminal pair on the 

 fourth leaf, and 3 mm. below in the case of the fifth leaf. 



A similar case was found on a plant six feet high of A. 

 decurrens var. normalis, the lower pinna being 4 mm. 

 below the terminal pair. 



On a seedling of A. pycnantha the fourth leaf was appar- 

 ently tripinnate, but in this instance, while the excurrent 

 point was between the central and right-hand pinnae, rt 

 was the central and left-hand pinnae which from their 

 position looked like the terminal pair. The outer pair 

 were opposite at their bases, but the left-hand pinna was 

 the most robust of the three, and the right-hand one began 

 to wither off as soon as it was fully developed. (Pig. 2.)

A strictly tripinnate leaf has, however, been found on a 

 sucker of A. Dorothea, at Leura. In this instance there is 

 no trace of any excurrent point at the base of the pinnae,.
