16208. Davidia involuckata. Davidia. 



From London, England. Received thru J. Veitch & Sons, November 2, 1905. 



In the whole vegetable kingdom there is not a more striking object than a tree 

 of Davidia when covered with its pure white bracts, which make it conspii-uous at 

 a great distance. It is a handsome tree, growing to a height of 60 to 70 feet, with 

 foliage nmch resembling that of our conjmon linden or basswood. When in full 

 flower it is said to be a marvelous sight, owing to the alternate white and green 

 caused by the large bracts intermingling with the leaves. The flowers themselves 

 are polygamo-diu'cious, all borne in heads inside a pair of large, white bracts about 

 3 inches long, with conspicuous red-anthered stamens and a long, bottle-shaped 

 gyno?cium. Botanically, the plant is allied to the dogwoods. 



Growing at an elevation of 6,000 to 7,000 feet in central China, where the minimum 

 temperature is about 5° F., there ought to be little doubt as to its hardiness in the 

 greater part of the L'uited States. Trees set out in France have survived the winters 

 at Paris, while others in England have withstood 15 degrees of frost unprotected. 

 Until well established, however, some protection in very severe weather is recom- 

 mended. New plants are readily obtained by cuttings or by layering, and should be 

 planted in a rich soil, with some protection from too much sunshine.
