Tilia alba 
6S ARBORETUM NOTES. 
LILIACEHZE: 
is certainly a distinct species from Tilia Europaea, 
as species are generally understood by Botanists. 
There is a clear and _ botanically important _ 
character in the scales (as they are called)* of the 
corolla; these scales are in appearance, super- 
numerary petals: they stand exactly opposite to 
the real petals, but appear to be separate from 
them from the very base, are of the same colour 
and texture, nearly equal in length, but much 
narrower, and are enveloped in the normal petals 
when these curl inwards in withering. 
* “ Nectaries,” according to the Linnean school.
