who, in figuring and describing the species, made the 
error regarding its identity, which has so long prevailed in 
this country with regard to the identity of P. serrulata, 
states that the timber of this tree is highly esteemed in 
Japan for wood-carving and for the preparation of the 
blocks used in printing cloth and wall-paper. In its native 
habitat the tree is stated to attain a height of eighty feet 
with a trunk three feet in diameter. Since its introduction 
to cultivation P. Sargentii has proved one of the most 
beautiful of single-flowered cherries. Hitherto fruits have 
not been freely borne in this country, but in the Arnold 
Arboretum trees of the same generation as those at Kew 
present a striking appearance in the latter part of June 
because of the extraordinary abundance of their small black 
cherries. The seeds these afford provide the best means of 
propagation ; failing seeds the species can no doubt be 
budded on Mahaleb or Gean stocks. The leaves in autumn 
assume a beautiful dark red hue. The tree should be 
planted in good loamy soil in a sunny spot. 
Description.— Tree, sometimes reaching 80 ft. in height; 
trunk reaching 3 ft. in diameter; bark tawny, beset with 
large lenticels ; twigs blackish, glabrous. Buds narrowly

beneath, glabrous on both sides, main nerves 7-10 on each 
side; petiole slender, 3-1 in. long, with a pair of apical 
glands. Flowers rose-coloured, 14-14 in. across, in 2—4- 
flowered sessile umbels ; pedicels slender, up to 14 in. long, 
with glandular serrate basal bracts. Calya tubular, about 
23 jin, long, lobes ovate-lanceolate, acute, 2-23 lin. long, 
entire. Petals obovate, emarginate, 3 in. long, about § in. 
wide. Stamens 20-25, shorter than the petals. Ovary 
glabrous; style glabrous, rather longer than the stamens.
