Dedication. — In honour of Baron Sir Ferdinand von Mueller, 

 K.C.M.G., the distinguished Government Botanist of Victoria. 



We have used the generic term Albizzia instead of Fithecolo- 

 hium in deference to the advice of Baron von Mueller, who writing 

 us on the subject, sa3^s : — 



" If you look through the Iconography of Australian Acacias 

 and allied genera, you will find that the characters, on which 

 Pithecolohium by my celebrated friend Martins was founded, find 

 their counterpart in Acacia, and that accordingly also from Acacia 

 a number of species would on the same grounds require to be 

 separated. Indeed Vachellia has been distinguished by a pithy 

 pod for A. Farnesiana, but by common consent Vachellia became 

 discarded. It was not on light considerations that I overthrew 

 in the Journal of Bot. for 1872 Pithecolohium, at all events for 

 the Asiatic and Australian species, there being absolutely no 

 difference between these genera. Whether Pithecolohium can be 

 maintained for any S. American species I cannot positively assert. 

 It was founded on species with somewhat succulent pods, such as 

 the monkeys there feed on. Hence the name. But no difference 

 in other respects seems to occur among the Alhizzias of the eastern 

 and western world. Furthermore, the w^ell known genus 

 Gleditschia in Leguminos?e contains species with dry and succulent 

 legumens. What I said of Gleditschia applies similarly to the 

 still closer allied genus Prosopis.''
