about four hundred feet southeast of the Belvedere. 
Pendulous varieties of the maple, mulberry, mountain- 
ash, and elm are also cultivated, and all being of small 
size are serviceable for the smallest lawns. Perhaps the 
best as regards curious foliage is the weeping Russian 
mulberry (Aforus tartarica pendula), whose leaf is one of 
the most ornate among trees. A few of these and of the 
weeping ash and elm would do more to diversify the 
Park than any number of European varieties whose dif- 
ferences are purely microscopic. 
Nature has also been coaxed into that extremely dis- 
sected form of foliage known as the cut-leaved, beautiful 
examples of which in Japanese purple-leaved maple, su- 
mach, oak, and white birch are in the Park. Though 
botanically only ‘‘ varieties,’’ they are of far more pro- 
nounced effect than many of the distinct species, and are 
one of the most important innovations in landscape 
gardening that modern times have produced. Another 
quite as important is the purple-leaved foliage, with 
which the Park is well supplied ; if one will look over 
the wall in the vicinity of East Seventy-second Street 
—the best spot in the Park for studying purple and cut- 
leaved foliage—he will find admirable examples of purple 
or rose-purple leaves in white birch, Japanese and syca- 
more maples and beech, all within a hundred feet of each 
other. Some of the purple beeches in these grounds 
are simply magnificent. The Japanese plum, also in the 
Park, is becoming popular as a purple-leaved dwarf tree.
