FLORICULTURAL NOTICES. 
showy effect, it does not appear a very valuable species. Like G. canariensls^ it 
was kept in a greenhouse, and potted in sandy loam. Bot. Reg. 23. 
Impatiens glanduligera. The prime peculiarity of this fine Balsam is the 
curious little glandular hairs near the bottom of each leaf, and the round club- 
shaped stipules just below them, surmounted by similar glands. In other respects 
it is a remarkably rapid-growing annual, attaining, in one season, the height of 
twelve feet, notwithstanding the seeds had not been sown till the month of May. 
The leaves are verticillate, ovate-lanceolate, much serrated, strongly veined, and 
of a rather coarse appearance. The flowers are particularly handsome, of a deep 
reddish-purple, with a large concave open spur, spotted with red on a yellow 
ground in the interior. It does not require a high temperature, but delights in a 
moist atmosphere, with a moderate but equable heat. Tlie following passage, 
quoted by Dr. Lindley from the work of Dr. Royle on the Himalayan Flora, &c., 
may be useful to the cultivator of the numerous beautiful plants from that district : 
" There is a peculiarity in the hill-climate of India, where the moderation and 
equability of temperature, excess of moisture pn the atmosphere], and consequent 
smallness of evaporation during the rainy season, have been shown to be favourable 
to the existence of tropical plants." Balsams, Orchidaceae, and others that are 
considered as exclusive inhabitants of tropical regions, are then adduced, and are 
stated to remain " apparently unchanged for weeks together " at this period ; 
although " of so loose, moist, and cellular a texture, as would at any [pother] 
season in this locality be destroyed in a single day." Bot. Reg. 22. 
Ipomcea longif5lia. There is much of novelty in the habit of this meritorious 
plant, which was found by Mr. Hartweg, in the pastures about Leon, Mexico, 
and sent to the Horticultural Society, by which body it has been profusely distri- 
buted. " It is a half-hardy perennial, with a long spindle-shaped root, and a stem 
from four to five feet long, without any side branches ; " the foliage being oblong, 
and the large white flowers, with a purplish centre, axillary, solitary, and pro- 
truded on long peduncles. "The time of flowering is from July to September; 
each flower opening in the morning, and lasting all day, if not exposed to the 
mid-day sun, and each stem producing a fresh flower nearly every day. Being- 
very fragrant, it is well worth placing in the sitting-room during the blooming 
season, especially as the plant, when in flower, seems to require shade." From 
the nature of the roots, a rich soil is demanded in the summer season, but they 
must be removed from it and stored in a dry place at the decline of autumn. It 
may be propagated by seeds, and the young shoots can also be taken off when 
about two inches long, and managed as dahlia cuttings. Bot. Reg. 21. 
Milt5nia CANDIDA ; mr. flavescens. A trifling variation in the colour of 
the labellum is the sole circumstance which stamps this plant as a new variety, 
that organ being " yellowish, with a tinge of purple," and the column likewise 
" white or pale yellowish-white." Considering that M. Candida itself has a purple 
shade at the base of the lip, it is highly probable that the difference here noted is
