ARBORETUM NOTES. 79 
AG ERACEA: 
pearance both singular and beautiful when in... 
flower (in April and beginning of May); the platanoides 
flowers of a bright greenish yellow, are pro- 
duced in such profusion before a leaf appears, 
that the whole tree appears one mass of yellow. 
They are much frequented by bees and other 
honey-feeding insects. 
ACER SACCHARINUM. 
Loudon, v. 1, 411. 
Onevine tree im).the arboretum; planted 1831. Acer _ 
- F saccharinum 
m@his is rather the. American representative. of 
Acer platanoides than of Pseudo platanus, but 
very different from both in its infloresence; 
the flower pendulous and tassel-like, on long 
slender pedicels, while the main stalk of the 
corymb is very short. The leaves turn bright 
yellow, not reddish, in Autumn; and this I find to 
be the case also in dried native specimens from 
North America. 
I suspect from what I have observed in Acer 
platanoides and Acer campestre, that the autum- 
lai, colouring ofthe leaves is a very variable 
and uncertain character. 
dhe tree in our-arboretum bore fruit in the 
summer of 1864.
