 is quite hardy, withstanding freezing temperatures." (Peter liinxct.) 



Originally introduced under S. P. I. No. 23233 (Meyer's No. 301). but as it

55715. Prunus serrulata pubescens Wilson. Araygdalaceje. 



A tree up to 55 feet in height, with a trunk sometimes 7 feet In cir- 

 cumference and leaves with pale-green lower surfaces. The white or 

 pink single flowers are usually about four-flfths of an inch in diameter. 

 This variety, known as Kasumi saknra. has the widest distribution of 

 any of the Japanese cherries and flowers about two w(H>ks later than 

 Prunus serrulata spontanea, from which variety it differs chiefly in the 

 slight hairiness of the leaves. (Adapted from Milton. Chcrnct of 

 Japan, p. 31.)

 (P. mrgentii Rehder.) [dalaceie. Sargent's cherry. 



This variety, the Yama .mkura of nortliern Japan, is very similar to 

 Prunus serrulata pubeseens, except that the leaves are not hairy, and 

 the flowers which are pink or rose colored, rarely white, are usually a 

 little more than an inch in diameter. It is the handsomest of all the 

 wald cherries of eastern Asia and is the parent of several of the finest 

 double-flowered Japanese cherries. (Adapted from Wilnon, Cherries of 

 Japan, p. 35.)
