[The fewer pinnae and pubescent peduncles in the .Australian speci- 

 mens induced me formerly to doubt whether they really belonged to 

 the A. Farnesiana, especially as I had not then seen the fruit, and 

 the specimens generally were bad. But I have since seen both East 

 Indian and South American specimens agreeing precisely with the 

 Australian form, and passing gradually into the commoner Tropical 

 varieties. — G. B.]

 Arborea, glabra, ramulis parum angulatis, spinis crassis curvato-

[The specimens marked 76, from Victoria River, are nearly allied 



to A. Bidwelli, but differ in the longer leaflets, the shorter pods, and
