rea, and is perfectly hardy. The following account is from 
the Gardener’s Chronicle. “This charming shrub was in- 
troduced into Europe by Dr. Siebold, to whom our collec- 
tions are indebted for so many novelties, only to be pro- 
cured with the utmost difficulty. It deserves the atten- 
tion of all amateurs, as well for its hardiness as its elegant 
habit and beautiful flowers. The Dutch traveller found it 
cultivated in the Japanese gardens, and supposes its na- 
tive country to be Corea, or the north of China. It isa 
shrub, from six to nine feet high, and has upright, close, 
bushy, slender branches, which are covered with a smooth, 
ash-colored bark, that detaches itself at later periods in 
thin scales. The leaves are oval, or ovate-elliptic, rounded 
at their base, obtuse or a little acute at their apex, downy 
beneath, denticulated at the edge. The flowers, which 
grow by threes or sixes, cover the whole length of the 
branches, are as white as snow, and very double, in conse- 
quence of a complete abortion of their stamens. Their 
shape is exactly like that of the Ranunculus aconitifolius 
with double flowers, and their number and arrangement, 
with a light and elegant bright-green foliage, render this 
plant a charming addition to the shrubs which grow in 
the native air.” It flowers in this climate in May. 
§. Douglasii.m Mr. Douglas’s Spirzea. — This shrub is 
from California, and has some resemblance to S. tomentosa, 
flowering in the same manner; flowers fine rosy-lilac, con- 
tinuing in bloom from July till the autumnal frosts com- 
mence. 
S. sorbifélia.—Pinnate-leaved Spirea.—This is a vigor- 
ous shrub, a native of Siberia. It develops its handsome 
pinnate foliage very early in the spring. The leaflets are 
serrated, or with notched edges. The flowers are yellow- 
ish-white, produced in large, dense panicles, in June. The 
flowers seem to be peculiarly attractive to the rose-bugs, 
which sometimes disfigure and spoil their beauty by the
