In the forests of central and western China this handsome tree is only surpassed 
in size by Cercidiphyllum. It is very abundant in western Szech'uan, but is less com- 
mon in Hupeh. It selects moist slopes and bottom-lands in the neighborhood of 
mountain streams and makes a much-branched, rather flat-headed tree, 16-30 m. tall, 
with a girth of 4-6 m. The bark is nearly smooth, persistent, pale gray or rufous- 
gray according to situation; the wood is white, brittle and of little value. A picture 
of this tree will be found under No. 121 of the collection of Wilson's photographs 
and also in his Vegetation of Western China, No. 484.
