This charming tree, though so long known in cultivation, 
has never before been well figured in this country. It has a 
very wide distribution; in Siberia it occurs in the eastern 
districts of Lake Baikal and in Dahuria; thence it passes by 
the Amur river north of China into Japan, whence we have 
numerous specimens. In the Himalaya it extends from the 
Indus to Kumaon, at elevations between 6000 and 11,000 
feet, entering the Tibetan region of Piti; and it was gathered 
by Dr. Thomson and myself in the Moflong woods of the 
Khasia mountains, at an elevation of 6000 feet. Tt varies 
very much as to the pubescence of its parts; the Siberian 
and Japanese specimens being almost wholly glabrous; the 
Western Himalayan having more or less pubescent calyces, 
pedicels and petioles, and sometimes young leaves beneath ; 
whilst those from the dry region of Piti, on the border of 
Tibet, are as glabrous as the Siberian; and those from the 
very wet region of the Khasia are the most pubescent of any. 
this correlation of humidity with pubescence 1s not unusual 
in the vegetable kingdom. : 
The figure of P. éaccata is taken from Kew specimens,
