NEW FLOWERS AND PLANTS. 
45 
length, and separating into a five-lobed limb 
of about half an inch in diameter ; the colour, 
as the name implies, is a fine dark blue, 
deepening near the extremities, and merging 
into a bluish green towards the calyx ; the 
throat is of a yellowish tinge. A very de- 
sirable species for the open border, or even a 
rockery. Native of the mountains of Co- 
lumbia. Introduced to the Belgian Gardens 
in 1846. Flowers in June and July. Cul- 
ture. — Nearly hardy ; requiring shelter in 
wet or severe winters, when it may be kept 
in pots in a greenhouse or dry airy frame ; 
rich loamy soil ; propagated by seeds, or by 
division. 
Epidendrum sulphureum, Morren (sul- 
phur-flowered Epidendrum). — Orchidaceas § 
Epidendreas-Lailiadas. — A pretty species, 
with oval conic pseudo-bulbs, from which 
short unilateral stems issue, having en/tire, 
smooth, linear lanceolate, attenuated, obtuse 
leaves, furrowed down the middle, keeled 
underneath, and partially two-lobed at the 
points. The flowers are numerous, and pro- 
duced in short racemes, usually from eight 
to ten in number, and forming a graceful 
panicle, the stem of which springs from the 
axils of the leaves ; the petals and sepals are 
of equal size, and of an ovate-lanceolate form, 
the sepals being slightly spathulate, and of a 
uniform sulphurous colour ; the labellum is 
three-lobed, the two side ones red, three- 
angled, and pointed ; the intermediate one 
broad, oval, crenated, and beautifully lined 
with rose colour, which terminates at the 
column in red streaks. Native of Guatemala. 
Introduced in 1847. Flowers in the summer. 
Culture. — Requires a moist stove ; turfy peat 
soil; propagated by division of the plant. 
Barkeria melanocaulon, Richard and 
Galeotti (dark-stemmed Barkeria). — Orchi- 
dacse § Epidendreas-Laeliadre. — A graceful 
little plant with small round fleshy roots, and 
growing up with a straight round stem of 'a 
dark brownish colour at the base, and bearing 
small distichous, ovate lanceolate alternate 
leaves, commonly four in number, attenuated 
at both extremities, and recurved at the 
points. Immediately above the leaves are a 
number of bracts, usually three ; they are 
straight, lanceolate, and clasping the stem at 
their base, the undermost being considerably 
longer and broader than those above it. The 
flowers are borne on a pendant raceme from 
the apex of the stem ; they are from twelve 
to fourteen in number, an inch and a half 
broad, about half an inch apart, and of a rosy 
lilac colour ; the petals are oval, attenuated 
at the points, and about thrice as broad as the 
sepals, which are linear-lanceolate ; the lip is 
two-lobed, sinuated at the margins, and having 
a double, obtuse, or roundish notch in the 
middle, the column being of a purplish colour, 
which merges into green at the base. Native 
of Mexico. Introduced to the Belgian Gar- 
dens in 1848. Flowers in June. Culture. — 
Requires a stove; turfy peat soil ; propagated 
"by division of the plant. 
Brassia coryandra, Morren (helmet-co- 
lumned Brassia). — Orchidacea3§Vandece-Bras- 
sidas. — A distinct and interesting epiphytal 
species. The psendo bulbs are conical, com- 
pressed, and each bear one lanceolate pointed 
leaf, which is shorter than the flower-stems. 
The flowers are produced in pendant racemes, 
and are beautifully variegated with green and 
white ; the sepals are very long — three to four 
inches — linear and acuminate, the upper one 
smooth, straight, and turned down ; the petals 
are divaricated, linear-lanceolate, shorter than 
the inferior sepals, which are the longest ; the 
colour of both sepals and petals is pale green 
spotted with brown near the base ; the lip, 
which is white spotted with green over its 
lower half, and having a yellow crested plate 
at the base of the column, is elongate-pandu- 
riform, about half as long as the petals, 
lengthened out into an acuminate point, which 
is reflexed. Native of Brazil. Introduced to 
the Belgian Gardens in 1848, by Mr. A. Vers- 
chaffelt, of Ghent. Flowers in June. Cul- 
ture. — Requires a moist stove ; turfy peat 
soil ; propagated by division of the plant. 
Dossinia marmorata, Morren (marbled 
leaved Dossinia). — Orchidacese § Neottese- 
Physuridaa. — This is one of that group of 
dwarf creeping stemmed orchidaceous herbs, 
whose greatest interest lies in the appearance 
of the foliage, which looks like a velvet surface 
overlaid with lustrous metallic veins. Some 
species of the genera Ansectochilus and Phy- 
surus, having these characters, are not un- 
frequently met with in English gardens. The 
present species is of very recent introduction. 
It has a sub-repent habit, the stems being 
fleshy and assuming an erect position at the 
apex. The beauty of the plant consists in 
the colour and marking of the leaves, which 
are seated rather close together at the base of 
the upright part of the stem. When in bloom 
the plant rises with an erect rose-coloured 
stem about a foot in height, the flowers 
being arranged as a lengthened raceme-like 
spike on the upper part, the apex being re- 
curved. The leaves are ovate, attenuated 
towards both extremities, having a velvety 
surface, rich dark green with a mahogany 
coloured stain, clouded with yellowish green, 
and netted over with clear yellow lines, re- 
sembling the veins in marble ; these lines do, 
in fact, mark the reticulated veins of the 
leaves. The under surface is similarly marked, 
but less velvety, and of a paler colour. The 
flowers are small, and not attractive ; the sepal
