The beautiful Lime here figured has long been a puzzle 
to arboriculturists. There are many specimens of it at 
Kew, where it has long been cultivated under the names of 
Tilia americana pendula, T'. alba-pendula, T. platyphylla- 
pendula, and 1’. argentea pendula. The first of these being 
the most frequent name, I directed Dr. Asa Gray’s atten- 
tion to this tree when in this country in 1882, and he at 
once declared against its being an American species, and 
suggested a comparison with the little known T. petiolata 
of De Candolle, a tree of which neither flower nor fruit were 
described, nor anything further known of its origin than 
that it is cultivated in the Garden of Odessa in the Crimea. 
This species De Candolle places next to the Hungarian Lime 
(1. argentea, Hort. Par.; T. alba, Waldst. and Kit.), and 
separates it from that plant by the leaf-blade being only 
twice as long as the petiole, whilst that of T. argentea is 
four times as long. Referring to the Herbarium, the only 
- specimen I find named T. petiolaris is one cultivated at 
_Therapia, near Constantinople, collected and named by 
_ Montbret, and communicated to Sir W. Hooker by the late » 
_ P. B. Webb. There are, however, two other specimens 
which agree with it; one called 7’. argentea, collected by 
_ Noe in the Bithynian Olympus, and the other named 7’. alba, 
_ from Hungary, collected by Pfendler. Unfortunately none 
of these are in fruit, and as the White Lime has often 
petioles as long in proportion to the blade as those of 7.
