FLORA AND SYLVA 
American seed, in no way corresponds with 
the true D. parviflora of botanists. After de- 
scribing this German seedling, he declares it 
to be (as M. Lemoine has suggested) a natural 
cross which he calls D. angustifolia^ and this 
hybrid origin seems certain in view of the fact 
that gracilis and parvijiora grew side by side 
in the Arnold Arboretum, and nothing would 
be simpler than this accidental crossing. 
D. scabra. — To M, Lemoine we owe the 
reintroduction of this old but scarce shrub, — 
the true D. scabra of Thunberg, — a plant al- 
together distinct from the D. scabra of gardens, 
which is a mere form of D. crenata and hardly 
distinguishable from it. This beautiful shrub 
is from Japan, flowers fully three weeks in 
advance of its namesake, and is quite hardy 
but shows its buds so early that our late frosts 
sometimes catch it. The stems rise rather 
weakly to a height of 2 to 3 feet high, with 
a rough and bronzed surface, slightly hairy 
while young. The leaves have little or no 
stalk and are broadly oval in shape, finely 
toothed, waved and crisped like those of the 
Wayfaring Tree (Viburnum Lantana), strong- 
ly veined and roughly hairy in texture, deep 
green above and somewhat paler beneath. The 
stems spread somewhat loosely and are flowered 
from the very bottom, while all the side-shoots 
carry spike-like clusters of about 40 flowers, 
held very erect and widely open, half-an-inch 
or more across, and of snowy whiteness con- 
trasting prettily with the golden stamens and 
an orange-red disk. The flowers begin to ex- 
pand from the middle of May, and last long 
in beauty. 
A plant sent out by another French firm as 
D. Sieboldiana^ comes so near this plant that it 
may well be considered as a mere variety of 
it. While their hardiness and general appear- 
ance are the same, the D. Sieboldiana (of Chen- 
ault) differs in its longer leaves, which are less 
crisped and curled, as well as in the longer 
flower-clusters in which the petals are concave 
and irregularly undulating. This plant is said 
to force readily and well. 
D. staminea. — A tender shrub from the moist 
mountain valleys of India, which can only be 
grown with success in the warmest gardens, 
and when thoroughly protected. Its stems and 
branches are hairy while young, becoming 
smooth with age ; leaves lance-shaped, with 
unbroken edges, dark green above, and white 
and downy beneath. The flowers appear in 
June and July as a compact, terminal head of 
pure white, the petals triangularly pointed. 
Syn. D. corymbosa of Lindley. 
D. Fihnorina. — A new kind of great merit 
from the mountains of Setchuen (China) , raised 
from seed sent to M. Maurice de Vilmorin in 
1 897, Already over 4 feet, this plant bids fair 
to far exceed this height, throwing a number 
of stout woody shoots, clothed with soft, lance- 
shaped leaves of 3 inches, crisped and minutely 
toothed around the edges,the teeth just touched 
with white. The clusters of 20 to 35 large 
flowers are at first erect, but the slender stalks 
soon droop under the weight of the expand- 
ing flowers and hang horizontally, their number 
and graceful carriage making this one of the 
most charming of Deutzias. It is perfectly 
hardy, flowering from the early days of June, 
and distinct in effect from older kinds. The 
individual flowers are nearly an inch across, 
and snow-white, with their petals lightly 
crumpled. 
As regards their general features, M. Le- 
moine would divide the Deutzias into four 
groups as follows: — Group I., containing only 
D. crenata with its many single and double 
i forms. Group II., including smaller and less 
vigorous shrubs of slender growth, with flowers 
appearing early : — D. gracilis^ D. discolor and 
its forms, and D. Vilmorina. Group III., con- 
sisting of early-flowering kinds with rounded 
and widely opened flowers,suggestive in general 
appearance of the Hawthorn, or certain Spir- 
eas : — D. parviflora^ D. scabra (of Thunberg) 
and its form D. Sieboldiana^ and D. corymbosa. 
Group. IV., comprising late-flowering kinds 
mostly from warmer climates, and too often 
tender in our gardens ; they are further distin- 
guished by their massive and much-branched 
heads of flower : — D. staminea^ and D. corym- 
bijlora. As already mentioned incidentally, D. 
crenata has so far resisted all attempts at cross- 
ing. Of the other kinds the best results have 
come from crossing the plants of Groups II. 
and III. ; while more recently crosses have 
been secured between the plants of Group IV. 
on the one hand, and those of Groups II, and 
III.
