pubescent pedicels and calyx-tube. S. Zenryi on the other 
hand is not so readily distinguishable from our plant by 
any striking difference in structure, though the two are 
unmistakable when seen growing side by side. But apart 
from their difference in habit, S. Henryi will be easily 
recognised by its much more frequently and more coarsely 
toothed leaves, which are slightly lustrous and are less 
pubescent, as well as by its laxer corymbs, with pilose 
pedicels and a hairy calyx-tube. S. /denryi, moreover, 
flowers about a fortnight later than S. Wilsoni does. Like 
nearly all the Spiraeas, S. Wilsoni is easily cultivated 
where a good loamy soil is available. It is advisable to 
remove old flowering branches that have become worn out, 
but any shortening back of the shoots must be avoided. 
The plant flowers on short branchlets produced on the shoots 
of the previous summer; the aim should therefore be to 
have the latter as long as possible and to prevent them from 
becoming unduly crowded. Propagation is readily effected 
by making cuttings of side twigs with a “heel” in the 
month of July; the flowers open in June. The material 
from which our plate has been prepared was supplied from 
one of the original plants of this species growing in the 
nursery of Messrs. J. Veitch & Sons at Coombe Wood. 
_Derscriprion.—Shrub, of graceful habit, ultimately 6-8 ft. 
high, with long arching branches and purplish pubescent 
young shoots. Leaves deciduous, rather firm, oval or 
obovate or oblong, somewhat acute or quite blunt at the 
nip, cuneate at the base, either entire—especially on the 
flowering branchlets, or with a few teeth near the apex 
only ; $-2} in. long, 2-1 in. wide; dull greyish green and 
pubescent above, paler and more closely pubescent beneath, 
ciliate ; petiole 1 in, long or shorter. Corymbs terminal 
on short lateral branchlets, com pact, rounded, many-flowered, 
13-2 in. across ; peduncles and pedicels sparsely pilose or 
glabrous. Flowers pure white, } in. wide. Calya with 
5 triangular lobes rather shorter than tube, margins of 
lobes ciliate, otherwise quite glabrous. Petals 5, suborbi- 
cular, Carpels 5, yy in. long, minutely pilose, dehiscing 
ventrally.
