NEW AND RARE PLANTS. 
heat. Where it can he had, the heat of fermenting materials is the best for stove plants of all 
kinds, and in it they will not only grow faster, but may be kept more free from insects than 
under any other treatment. Towards August, when the plants have completed their summer's 
* growth they must be fully exposed to the sun, admitting air very freely, but still maintaining 
a high temperature. As the wood gets thoroughly matured some of the leaves will fall off; 
but never mind that, as it shows the object you are aiming at is attained. As the wood ripens, 
decrease the supply of water, and through the winter it must be supplied very sparingly, and 
a temperature of sixty degrees will be quite sufficient to keep the plants in health. The R.ou- 
pellia rarely flowers the first season, and if you get a strong plant, take care in the second 
year to get short stubby well-ripened wood, from which the flowers mil be produced. Mr. 
Cole, the successful gardener to Mr. Colyer, to whom we are indebted for an opportunity 
of figuring the plant, says, he has no fear but that in another season he “ will bloom it as freely 
as an Ixora;” and if so, it will certainly be one of our finest exhibition plants.—A. 
The generic name Roupellia has been applied in honour of the family of Roupell, several 
members of which are active promoters of botany.

Maranta ornata, Linden. Ornate Maranta ( Flore des Serves , v., 413 and 414).—Nat. Ord., Marantacese.— 
A very conspicuous and elegant-leaved stove herb, of which the proper generic name remains doubtful until 
flowers have been examined. The leaves are ovate-lanceolate, of a rich deep green, tinged on the under side as 
well as on the stems, with a rich stain of purple. There are two forms of this plant:—1, albo-lineata , in which 
the leaves on each side the midvein have a series of divergent narrow, but clear white lines, giving them a very 
distinct and interesting appearance; and, 2, roseo-lineata , in which the leaves have a similar series of marks, hut 
of a clear delicate pink colour. It is, however, said that markings of both these colours are sometimes seen on the 
same plant. From Columbia. Introduced in 1848. Flowers in ? 
Neippergia chrysantha, Morren. Golden-flowered Neippergia ( Ann . de Gand ., t. 282).—Nat. Ord., Or. 
chidacese § Yandese-Maxillaridas.—Syn: Acineta chrysantha, Lindley .— A very handsome stove perrennial. The 
pseudo bulbs are large, ovate, and streaked, bearing each three to five lanceolate plaited leaves upwards of a foot 
long. The flowers are numerous on an erect (?) scape, which issues from the root, and reaches eight or ten 
inches in height; these flowers are erect, an inch and a half across, and from twenty to thirty on the scape, and of 
a golden yellow colour, relieved by purple dots, the lip white, and the column crimson; they are scentless by day, 
but have a sweet aromatic odour at night and in the morning. The plant requires the treatment of other terres¬ 
trial stove orchids. Supposed to be from Mexico. Introduced to Belgian gardens in 1848. Flowers in autumn. 
Achimenes gloxinielora, Lemaire. Gloxinia-flowered Achimenes.—Nat. Ord., Gesneraceae § Gesnerese.—A 
very beautiful stove herbaceous plant, with scaly rhizomes, slender erect flexuose stems, bearing opposite 
pale green leaves, serrated from near the middle to the apex. The flowers are axillary large, with a funnel-shaped 
tube, rather more than two inches long, inclined, and dilated beneath, the limb broad, spreading, five or six lobed, 
finely and equally crenulated on the margin, white ; the throat wide with a fine tinge of golden yellow, which 
is prolonged to the base of the tube; on the whole inner surface are myriads of small purple dots, which have a 
peculiarly pleasing effect. From Mexico. Introduced to the Boyal Garden at Lacken, in 1844, by M. Ghies- 
breght. Flowers in the summer. 
Lycaste chrysoptera, Morren. Golden-winged Lycaste {Ann. de Gand., t. 232).—Nat. Ord., Orchidaceee § 
Yandese Maxillaridse.—A handsome stove epiphyte, with ovate compressed pseudo-bulbs, bearing each one broadly 
lanceolate plicate leaf from its summit, and one-flowered scapes from its base. The sepals are spreading, broadly 
ovate, oblong acute, of a deep yellow ; the petals shorter, erect, oblong, deeper orange yellow, with crimson 
dotted lines at theff base ; the lip is short, oblong, concave, with three reflexed lobes, the intermediate one lanceo¬ 
late, plicate-undulate, with crisped margins, the lateral ones abrupt; the colour is the same as that of the petals. 
The flowers have a most delicious and lasting aromatic fragrance. From Mexico. Introduced to the Belgian 
Gardens, in 1846, by the collectors of the Belgian Government. Flowers in autumn. 
Ceanothus rigidus, Nuttatl. Ptigid Ceanothus. — {Journ. Hort. Soc ., v. 197).—Nat. Ord., Bhamnaceae.—A 
rigid, much branched evergreen shrub, nearly or quite hardy, growing in its wild state to the height of four feet. 
The branches are downy when young, and are furnished with small persistent, truncate, subsessile, spiny-toothed 
leaves, smooth and shiny on the upper surface; netted, paler, and hairy beneath. The small flowers grow in 
clusters or umbels at the end of the very short spur-like branches, and are deep purplish-violet in colour, “ less 
showy than those of C. dentatus or C. papiUosus.” From California: open places in woods near Monterey. 
Introduced in 1848 by Mr. Hartweg. Flowers in summer, or in the open air apparently in autumn. Horticul¬ 
tural Society of London.
