68 ARBORETUM ET FRUTICETUM BRITANNICUM. 
102. Tilia alba. 
(Steven.) Host says that he has always found the calyx 6-sepaled, and the 
corolla J2-petaled. A large tree. Hungary. Height 30 ft. to 50 ft. In- 
troduced in 1767. Flowers yellowish white, very fragrant ; June to August. 
Fruit yellow; ripe in October. 
Our own opinion is, that this is nothing more than a very distinct race of 
the common lime ; notwithstanding the circumstance of its having scales to its 
petals, which no one of the other varieties of J. europze‘a is said to possess. 
Even allowing this structure to be permanent in the Hungarian lime, the tree 
bears such a general resemblance to 7’. europee‘a in all its main features, that 
it seems to us impossible to doubt the identity of their origin. We are 
strengthened in this opinion by the circumstance of its being found only in 
isolated stations in the Hungarian forests. We have, however, placed this 
lime by itself, rather than among the other varieties ; because, from the white- 
ness of its foliage, it is far more obviously distinct than 7. e. grandifolia or 
T. e. parvifolia. The tree is at once distinguishable from all the other species 
and varieties by this white appearance, even at a considerable distance, and 
by the strikingly snowy hue of its leaves when they are ruffled by the wind. 
Its wood and shoots resemble those of the common lime; but it does not 
attain the same height as that tree.
