the Jardin des Plantes, Paris, and the other to Kew. The layer 

 was intended for Prof. Sargent. ■ In May of last year the original 

 plant flowered, and figures appeared in the Revue Horticole, 

 p. 297, and in the Gardeners" Chronicle, vol. xxxix., p. 346, and 

 Mr. M. de Vilmorin presented Kew with a good herbarium 

 specimen. In 1889, twenty years after David's discovery, Dr. A. 

 Henry sent good flowering and fruiting specimens to Kew, and 

 Prof. D. Oliver described and figured the fruit in Hooker's Icones 

 Plantarum t. 1961. Henry's specimens were taken from "the 

 only tree observed during a six months excursion." It grew in 

 South Wushan on the Yangstze-kiang, just 

 boundary of Szechuen. 



Ten years later Mr. E. H. Wilson went to China to collect for 

 Messrs. James Veitch & Sons, one of the principal objects of the 

 mission being to procure seeds of Davidia, in which he was highly 

 successful. He was fortunate in discovering a considerable grove 

 of trees to the south-east of Wushan between Patnng and Nanto, 

 Hupeh, in about 110° 45' longitude. There he found abundance 

 of seed, which he transmitted to Messrs. Veitch, who raised a 

 large number of plants ; and the writer described and illustrated 

 the germination and early condition of the seedlings in the

 Szechuen, in about 102° 40' long, and 30° 20' lat. ; and in 1904 he 

 collected further specimens on Mount Omei, in about 103° 40' 

 long, and 29° 30' lat. 



Previous to Mr. Wilson's departure on his third journey to 

 wuna, he called my attention to certain differences exhibited by 

 the specimens of Davidia from different localities, and I have 

 since examined the rich material at Kew
