Western Hupeh: near Ichang, alt. 300-600 m., April and Decem- 

 ber 1907 (No. 685, type); south-west of Ichang, alt. 300 m., Novem-

Allied to Photinia serrulata Lindley, which has prominent winter-buds 3-4 mm. 

 in diameter, perfectly glabrous and somewhat thicker leaves, the petioles 2-4 cm. 

 long, perfectly glabrous shoots and inflorescence, smaller flowers about 6-7 mm. in 

 diameter and smaller ovoid fruits about 5 mm. in diameter, with the branches of 

 the inflorescence shorter, rather thick and angular in the dried state. 



This new Photinia is one of the handsomest evergreen trees in central China 

 and is commonly planted around shrines and tombs. The short interior branches 

 are frequently spinescent. The name "Tung-ching" (winter-green) is sometimes 

 applied to this tree, but this name properly belongs to Xylosma raccmosum Miquel. 

 A photograph of this tree will be foimd under No. 678 of Wilson's photographs.^
