NEW n.ANTS IN THE HORTICULTURAL SOCIETY S GARDEN. 
»li 
grow in close cymes of from nine to eleven 
each, on stalks somewhat shorter than the 
leaves. They are of a clear bright blue, and 
very handsome. The corolla is an inch and a 
half across, with a Hat limb, a very short tube, 
and long projecting stamens. The species lias 
been regarded by M. Choisy as a variety of 
Jacqutmontia violacea, the Convolvulus pent- 
anthus of gardens, but it is certainly quite 
distinct and far handsomer. It grows freely 
in soil composed of equal parts of peat and 
loam, mixed with a little sand. In this country 
it must be treated as a green-house climber, 
and its slender stems trained round a trellis 
fixed in a pot, or it may be planted out in the 
border of the house and trained up the rafters. 
In cither place it will succeed very well, and 
flower abundantly during summer and autumn. 
It strikes readily from cuttings prepared in 
the usual way. It is a welcome addition to 
our collections of green-house creepers, as its 
habit is neat, and the flowers are of the same 
colour and larger than in the J. violacea just 
noticed. — Fusagasvga, in Bogota, Mr. Hart-

Lysimachia Candida, (white flowered Loose- 
strife.)— This is a dwarf, compact, dark-green 
herbaceous plant, growing about a foot high. 
It is perfectly smooth. The radical leaves 
are narrowly oval, tapering into the stalk, and 
about four inches long ; those of the branches 
are very narrow, and somewhat spathulate ; 
all of them are very obscurely toothed at the 
edge, or show some tendency to be so, and are 
marked by scattered dark-purple dots, which 
are not seen unless the leaves are viewed by 
transmitted light. The flowers grow in close 
racemes, are white, and have much the appear- 
ance of those of L. Ephemerum, but the 
corollas are much larger. From the short 
time is has been in the garden it is impossible 
to state what its proper mode of treatment may 
be. It will in al! probability prove hardy, or 
at least enough so for bedding out in the 
flower-garden. It appears to be a plant of 
free growth, and likely to succeed in any sort 
of soil. From the profuse manner in which it 
blossoms, it will doubtless be abundantly mul- 
tiplied from seed. — liaised from the soil con-

Oncidium unguiculatum, (unguieulate, or 
clawed-lipped Oncid.) — This is one of the 
finest yellow Oncidiums in cultivation. Its 
oval shining pseudo-bulbs are three inches 
long. The leaves are a foot long and )}, 
inch wide. The scape is three feet high, and 
divided into several slender straight rod-like 
branches, over which, at the distance of about 
two or three inches, are scattered the. fine 
large flowers in a one-sided manner. They 
are nearly 2\ inches long and about I ', inch 
wide, so that they present to the eye a 
somewhat narrowed appearance. This is 
owing to the form of the lip, which is pure 
bright yellow, with a long stalk to the trans- 
verse two-lobed middle segment. The sepals 
and petals are greenish-yellow, spotted with 
brown. We have no Oncidium in cultivation 
to which this bears much resemblance. It is, 
however, apparently allied to the O. macro- 
ptcrum of Kichard and Galeotti, if any judg- 
ment can be formed from the slight specific 
character of it, published in the Annates ties 
Sciences. In that plant, however, the column- 
wings are said to be extremely broad, and no 
allusion is made to the very remarkable 
length of the stalk of the middle lobe of 
the lip. — Purchased at a sale of Mexican 
Orchids. 
Platijcodon grandiflorus, with semi-double 
white flowers. — This is a striking variety of 
the beautiful Platyeodon grandiflorus, remark- 
able for having pure white blossoms, consisting 
of one flve-lobed corolla placed within another 
so exactly that the two constitute a large white 
star of ten points. There is no tendency to 
further irregularity of structure, unless it be 
that the two corollas of this variety are flatter 
than the single one of the wild blue form. 
Although it is doubtful whether or not this 
beautiful thing will prove hardy, few will 
deny it room in their green-house. It appears 
to grow freely in any sort of soil, and to re- 
quire an ample supply of water in summer. 
Like the generality of plants with fleshy roots, 
it must be put to rest in autumn, so that 
in winter it may be kept quite dry. In spring 
it may be re-potted and started to grow in 
the usual way. It strikes very freely from 
cuttings. — China, cultivated in nursery gar- 
dens near Shanghae, Mr. Fortune, April, 
1845. 
Stcnanthiitin frigidiini, (frigid Stonan- 
thium.) — This is a perennial grassy- leaved 
plant, very much like a tuberose in appear- 
ance before it conies into blossom. It is re- 
markable for the dull blackish-purple colour 
of its flowers, which appear in drooping pani- 
cled leafy racemes at the tup of a leafy stem 
about three feet high. The only inter* st that 
attaches to this plant consists in its poisonous 
qualities. From the name under which it 
was sent home by Mr. llartweg (Cebadella de 
tierra fria) it may be supposed to furnish a 
part of the venomous Sabadilla seeds of com- 
merce, from which Veratria is prepared. Dr. 
Schiede says (Linnaa, vol. iv. p. 226,) that 
the inhabitants of Mount Orizaba, where it 
grows wild, know it to be dangerous to the 
horses that bite it ; and in another place that 
it is called the "Scvoej.i." It is probably a 
hardy perennial, requiring to be grown in 
peat >"il aud a rather moist situation during
