732 ARBORETUM AND FRUTIGETUM. PART III. 
Spec. Char., §c. Leaves stipuled, pinnate ; the leaflets sessile, opposite, 
lanceolate, doubly and sharply serrated. Inflorescence a thyrse-like panicle. 
Torus wholly connate with the tube of the calyx. Ovaries connate, 5. A 
native of Siberia, in moist places. (Dec. Prod., ii. p. 545.)

S. grandiflora Hort. Brit., No. 29267., and Sweet’s Hort. Brit., 
p. 194.; S. Pallas# Don’s Mill., ii. p. 520. —Suffruticose. Flowers 
twice the size of those of the species, and disposed in corymbs. 
Leaves smaller, and serrately incised. A native of eastern Siberia 
and of Kamtschatka. (Dec. Prod., ii. p. 545.) This is the S. 
grandiflora of Sweet’s Hort. Brit., and our Hort. Brit., and is 
very different from S. s. grandiflora, the S. grandiflora of Lodd., 
described before, among the varieties of S. salicifolia, p. 730. 
Description, §c. 8. sorbifdlia is a branchy 448 
shrub, growing to the height of 6 ft. or 8 ft., Wy, 
with a round, brown-coloured, warty stem ; 
the wood of which is brittle, and hollow within, 
with a soft ferruginous pith. The leaves are 
thin in texture, and bright green on both sides. 
The flowers are in terminating panicles, small 
and white: they are odorous, but not agree- g 
ably so. According to Pallas, it is a native “ 
of eastern Siberia, in boggy woods and wet 
mountains, where it grows along with S. salici- 
folia, and attains the height of 6 ft. ; but, in 
dry rocky situations, it does not rise above 
1 ft. in height, and is subherbaceous. It was 
cultivated by Miller in 1759, and deserves a 
place in every collection, from its marked character, and from the beauty both 
of its foliage and its flowers. It throws up abundance of suckers, by which it 
is easily propagated. 


App. i. Species or Varieties of Spira‘a not yet introduced. 
XS. Blumei G. Don, S. chamezdrifdlia japénica Blume Bijdr., 1114., is a native of Java and 
Japan, with white flowers, and is, probably, nothing but a variety of S. chamedrifdlia, it being con- 
sidered such by the discoverer, Blume, though elevated to the rank of a species by G. Don. 
% S. lanceolata Poir. (Don’s Mill., ii. p. 518.) is a native of the Mauritius and China, with leaves 
like those of S. salicifdlia, and white flowers. 
2S. argéntea Mutis has the whole plant clothed with silky silvery down. Itis a native of New 
Grenada ; and, if introduced, would probably be found, at first, rather tender; but, if our conjecture, 
as to a constitution of truly natural genera be correct, it will be found capable of being accli- 
matised. 
%S. Thunbérgii Blume, and Don’s Mili., 2. p. 319., is anative of Java and Japan, with linear- 
lanceolate leaves, and white flowers. : 
2S. magellanica Poir, and Don’s Mill., 2. p. 519., has lanceolate leaves, and white flowers; and, 
being a native of the Straits of Magellan, will, doubtless, be found quite hardy. 
 S. japénica Sieb. ex Blume, and Don’s Mill.,2. p. 519., is said to resemble the preceding species. 
XS. Menziésii Hook. Fl. Bor. Amer., p. 173., and Don’s Mili., 2. p. 520., is thus described : — 
Branches pubescent at the apex. Sepals reflexed. Leaves elliptic. Panicle crowded with rose- 
coloured flowers. It would be a desirable introduction, and will, doubtless, soon be procured. 
XS. Dougilasii Hook. Fl. Bor. Amer., p.172., and Don’s Mi/l., 2. p.520. From Dr. Hooker’s 
description of this sort, it appears to us to be the same, or ;nearly so, as the preceding. It is a 
native of the north-west coast of America, about the Columbia and the Straits of Fucas where it 
is said to grow to the height of 4 ft. or 5ft. 
% S. callosa Thunb., S. expansa Wail., isa native of Japan and Nepal, and said to differ from 
S. salicifdlia in the leaves being nearly stalked. It grows to the height of 4ft., and has showy red 
flowers. 
& S. ceruléscens Poir. has sessile bluish-coloured leaves, and white flowers, and, being a native of 
India, would probably prove only half-hardy in British gardens. 
% S. discolor Pursh Fl. Amer. Sept., 1. p. 42., is described by that botanist from specimens 
which he saw in aherbarium. It is said to be found on the banks of the Kooskoosky ; to have dis- 
coloured leaves ; and to grow to the height of about 5 ft. 
Almost all the known species of Spire‘a being quite hardy, of the easiest culture, and very free 
flowerers, it is much to be desired that a part or all of the above species could be procured. We 
recommend the subject to those who have friends and correspondents in the countries where these 
species are indigenous.
