Spec. Char., §c. Stem somewhat branched. Leaves com- 
poundly divided; those of the stem pinnate, linear, gla- 
brous. Flowers about 5 in a head. Heads almost 
sessile, disposed unilaterally and reflexedly in spikes, 
which are in panicles. (Willd. Sp. Pl.) A native of § 
Siberia, Tartary, and Persia. It has been cultivated | 
since 1596 in British gardens, where it grows to the 
height of 1 ft., forming a low spreading bush, and pro- 
ducing abundance of whitish green flowers from Sep- 
tember to November. The leaves are very small, linear, 
and undivided. The seeds of this species were for- 
merly imported from the Levant, under the name of 
semen santonicum, or worm-seed; but the plant is now 
little used in medicine. It is, however, tonic, and 
stomachic; and, like many other plants now neglected, may be found useful 
to practitioners who depend for drugs on their own resources,

Spec. Char., §c. Leaves tripinnatifid, silky, grey; segments linear. Flowers 
in globose heads, that are borne on simple branchlets. (Willd. Sp. Pl.) A 
native of the Levant, Portugal, and the south of France, principally on the 
sea shore, where it grows to the height of 6 ft. or 8 ft., and produces its yel- 
lowish green flowers from June to August. The whole plant so much re- 
sembles the common wormwood, that Linnzus considered it only a variety 
of that species. It was cultivated in British gardens in 1640; Gerard calls 
it the greater, or female, southernwood, and says that, “ by careful manuring, 
it doth oftentimes grow up in manner of a shrub, and cometh to be as high 
as a man, bringing forth stalks an inch thick, or more, out of which spring 
very many sprigs, or branches, set about with leaves, diversely jagged, and 
finely indented, somewhat white, and of a certain strong smell.” This 
species makes a fine strong plant, and a fit associate for the strong-growing 
variety of the common southernwood. There are plants of this species in 
the Horticultural Society’s Garden, in the Chelsea Botanic Garden, and in 
the arboretum of Messrs. Loddiges ; and it well deserves a place, with A. 
Abroétanum and A. procéra, in collections. Plants are Is. 6d. each. 

App. 1. Other hardy Species of Artemisia. 
In our Hortus Britannicus, several species will be found indicated as ligneous and hardy; but, in 
general, they are of such humble growth, and so imperfectly ligneous, that, for all practical purposes, 
they may be more fitly considered as herbaceous plants ; unless we except 4. procéra, which is said to 
grow 8 ft, high, but which appears to us to be nothing more than A. arboréscens. 
App. ii. Half-hardy Species of Artemisia. 
The same remarks that we have applied to the hardy ligneous 
species in the preceding Appendix will apply to those which are 
half-hardy. Though there are a dozen or more of them enume- 
rated in our Hortus Britannicus, they are almost all too iow to be 
considered otherwise than as herbaceous plants. The most in- 
teresting of these is A. argéntea Ait. Hort. Kew., 3. p.170., L’ 
Heérit. Sert. Angl., t. 28, N. Du Ham., 6. t. 36., and our fig. 839. 
This species has bipinnated silky white leaves, with lanceolate 
linear leaflets. The flower heads are globose, and the flower-bearing 
branches wand-like. The whole plant is of a silvery colour. It 
is a native of Madeira, whence it was introduced in 1777; and, 
in British green-houses, it grows to the height of 4 ft. or 5ft., 
producing its yellowish green flowers in June and July. This is 
by far the handsomest species of the genus, and it used formerly Siz 
to be very common in green-houses. If placed, under favourable

circumstances, against a conservative wall, it would make a fine

appearance, associated with such shrubs as Anthyllis Barba
