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 Pithecolo- 
bium in deference to the advice of Baron von Mueller, who writing 
us on the subject, says : — 
" If you look through the Iconography of Australian Acacias 
and allied genera, you will find that the characters, on which 
Pithecolobium by my celebrated friend Martius 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 Pithecolobium, at all events for 
the Asiatic and Australian species, there being absolutely no 
difference between these genera. Whether Pithecolobium 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 Albizzias of the eastern 
and western world. Furthermore, the well known genus 
Gleditschia in Leguminosse contains species with dry and succulent 
legumens. What I said of Gleditschia applies similarly to the 
still closer allied genus Prosopis.''''
