THE GENUS IMPATIENS. 
nearest to the fall, and quite within the in- 
fluence of the spray: in this position, however 
favourable to exuberant vegetation, he did not 
observe it producing any flowers. It is an 
annual. 
1 m i-vT i F.\s PALLIDA (the pale -flowered 
Impatiens, or, Touch-me-not). — A North Ame- 
rican annual species, nearly related to I. Noli- 
tangere, with pale yellow flowers, very slightly 
dotted with red. This plant appears to be 
found in some parts of England ; and is, per- 
haps, hardly distinct from the common 
species. 
Impatiens Candida (White-flowered Im- 
patiens, or, Touch-me-not). — A stately annual, 
growing six feet high, under favourable cir- 
cumstances, with a bright green, obtusely four- 
angled succulent stem, branched to the very 
ground ; the leaves are generally in whorls of 
three, narrow-lanceolate, tapering to a fine 
point, and edged with minute crimson serra- 
tures, or teeth : between the leaves forming 
the whorls is situated a row of small crimson 
glands. The flowers are white, speckled 
slightly with crimson, large and showy ; they 
grow in loose terminal umbels, and are pro- 
duced in succession throughout the autumn. 
It was introduced from the Himalayan moun- 
tains, and though it will grow freely, and 
flower when treated in the open ground 
as a half-hardy annual, yet much of its 
delicacy is thus lost, and, in order to 
realize its full beauty, it should be grown in a 
green-house, in the same way as the common 
garden Balsam is cultivated. Nevertheless, in 
sheltered situations, the out-door plants will 
not be without interest. 
Impatiens rosea ( Small pink Impatiens, or, 
Touch-me-not). — This grows four or five feet 
high, with less of a branching habit than some 
of the other kinds. It is a beautiful half- 
hardy annual, from the Himalayas, with suc- 
culent upright stems, and linear-lanceolate 
alternate leaves, from six to eight inches long, 
tapering most towards the base, and edged with 
minute saw-teeth. The flowers, which are 
small, are produced in clusters from the axils 
of the leaves, on blood-red stalks, as long as 
the leaves, and of a delicate rose-colour. The 
seed-pods are oblong, and covered with white 
wool, and the paper in which the imported 
seeds were- packed, was marked " woolly- 
podded Balsam, found growing on old ruins." 
Like the others, it will admit of being grown 
both in the open ground, and in pots in the 
green-house : when well grown in the latter 
situation, a greater degree of delicacy is at- 
tained, though considerable beauty is developed 
out of doors. Like all other succulent, 
strong growing annuals, the out-door plants 
succeed best when the summer is hot and 
comparatively dry. The flowers of this kind, 
when gathered, are said to last for several 
weeks without fading. 
Impatiens glanduligera (Gland-bearing 
Impatiens, or, Touch-me-not). — This is one of 
the largest growing species, attaining as much 
as twelve feet in height when grown freely in 
a green-house, and from six to eight feet, under 
favourable circumstances, out of doors. It has 
a strong, fleshy, upright central stem, from 
which issue numerous branches, decreasing 
in size from the bottom upwards, and forming 
a thick, somewhat conical bush, with branches 
quite down to the ground. The leaves are 
large and lance-shaped, finely serrated on the 
edges, and growing in whorls round the stem ; 
the flowers are large and numerous in terminal 
umbels; they are of a deep rosy-purple colour, 
which, however, sometimes varies in the seed- 
lings to a lighter tint. The plants continue to 
bloom from the month of July, or earlier if 
reared early in the spring, quite through the 
summer and autumn months. It is a native 
of the Himalayan mountains, and so hardy 
that self-sown seedlings have been known to 
survive in the open air, through a mild winter. 
Being exceedingly handsome both in its habit 
and flowers, it is therefore deserving of cultiva- 
tion in pots, under glass, in company with it! 
near ally, the common garden Balsam (Balsa- 
mina hortensis), and in such situations its beauty 
becomes more fully developed; yet it may also 
be regarded as a very desirable half-hardy 
annual, adapted to situations where its size 
would not render it inappropriate. Dr. Royle 
raised this plant from Cashmere seeds. 
Impatiens macrochila (Broad-lipped Im- 
patiens, or, Touch-me-not). — This is an Hima- 
layan species, growing eight or ten feet in 
height, and of about the same degree of hardi- 
hood as the other Himalayan species ; that is, 
it will grow freely and flower in the open air ; in 
fact, it is as hardy as any of this class of 
annuals, growing when protected only from 
frost ; but it will also well repay cultivation 
in pots in the green-house, as a tender annual. 
It grows with an erect succulent stem, not so 
much branching as in I. glanduligera. The 
leaves are alternate on the stem, ovate-lanceo- 
late, smooth, serrated on the edges, and furnished 
with glands at the base; the flowers are pro- 
duced in umbels towards the points of the 
branches; they are large, pale rose-coloured, 
and showy. In habit, this species approaches 
I. tricornis. 
Impatiens tricornis (Three-horned Im- 
patiens, or, Touch-me-not). — This species 
grows four or five feet high. It has an erect 
stem, with alternate, hairy lanceolate leaves, 
without glands, from the axils of which the 
short racemes of flowers are produced ; they 
are pale yellow, slightly spotted with red. It 
is an annual, introduced from the North of
