been .sketched in our old as \Yell as new paintings. The 

 typical form, a. Jamasakura, which I have figured and 

 described in " Icones Florae Japonic^e," Vol. I. Part 1, under 

 the name of Prunus pseudo-Cerasus Lindl. «. spontanea Maxim., 

 is the so-called " Yama-zakura," or Mountain Cherry, and may 

 be the origin of our numerous cultivated forms, which all 

 belong to varr. /9. hortensis and y. Sieboldi of Maximowicz. 

 The appearence of the young reddish (very rarely greenish) 

 leaves and simple-flowers at the same time in Spring, and the 

 fugacity of the white-rosy-coloured (so-called * sakura '-colour 

 of Japanese) petals are the common peculiarities of this tree. 

 The leaves commonly fall off in early autumn before many 

 other trees do so, assuming more or less a red tint ; but in 

 the northern part it turns a brighter scarlet. The discoid 

 glands of the leaves secrete sweet juice to invite the ants. The 

 fruits mature in May-June, but are scarcely eatable owing to 

 their more or less bitter taste. The wood is hard, fine, close- 

 agained, with very fine and copious medullary rays, the heart- 

 vv^ood, or duramen, reddish-brown in colour, v^hile the sap-wood, 

 or alburnum, is of pale yellowish colour, it is exceedingly 

 valuable, being especially fitted for engraving, but also made into 

 various furniture. The bark is tenacious and smooth, and 

 is also useful for various purposes.
