THE GARDENING WORLD. 
September 12, 1891. 
About four to six flowers, 2.J in. to 3 in. in diameter, 
are borne on a scape, and they are of a warm pink 
and white, beautifully netted with darker veins that 
give them an attraction which even more gaudy 
flowers do not possess. The species was introduced 
from Brazil in 1677. 
THE MACARTNEY ROSE. 
Ordinarily this Rose flowers in July, but late 
growths are sometimes produced, and which flower 
in September. The flowers are large, single, pure 
white, and developed singly or in small clusters ter¬ 
minating the shoots. The species is distinguished 
from others b}' the presence of three or four largely 
developed bracts beneath each individual bloom, and 
derives the name of Rosa bracteata from this circum¬ 
stance. The leaves consist of seven to nine oblong, 
deep green leaflets, of which the lowest pair is the 
smallest. The spines of Roses are usually reversed 
or hooked, but in this case they are straight or 
slightly upcurved. Being of a subclimbing nature a 
very good way of growing the species is to train it 
against a wall or wooden fence, where it will run up 
to 6 ft. or 8 ft. As a bush it may not exceed 
2 ft. or 3 ft. in height. It was introduced from China 
in 1795- 
CUPHEA ZIMAPANI. 
Like the plant known as Dahlia Zimapani this 
Cuphea is a native of Mexico, from whence it was 
introduced in 1878. It may be raised from seeds 
sown under glass in March and April, and planted 
out when the weather becomes fine. The stems are 
well furnished with large, ovate, bright green leaves, 
and come into bloom during August. Flowers con¬ 
tinue to be produced till cut down by frost, if the 
soil in which the plants are growing is moderately 
rich and moist. Good drainage is, however, 
essential. The flowers are amongst the largest of 
those commonly seen in cultivation, and rich in 
colour. The tube of the calyx is deep crimson- 
purple. All the five petals are present, which is not 
the case with some of the best known species. They 
are of a dark crimson-purple, and the two upper 
ones are both larger and darker. The plant has a 
bold and attractive appearance, whether grown in 
clumps in the border, or as an edging to large beds 
of herbaceous plants or shrubs. 
EXACUM PEDUNCULATA. 
In general appearance this species somewhat resem¬ 
bles E. affine, but the flowers are smaller and even 
more abundantly produced, so _that what they lack 
in size they more than make up in numbers. The 
stems vary from 4 in. to 10 in. in height, and are 
branched with all the shoots terminating in cymes of 
bright blue flowers, with greenish eyes and a cone of 
bright yellow stamens; the corolla is four-parted. 
As in other species the leaves are opposite, a cir¬ 
cumstance that helps largely in enabling us to place 
Exacum in the order of Gentianworts. The two- 
celled ovary and the cone of stamens point strongly 
to the Solanum family. The leaves are also lanceo¬ 
late, three to five-nerved, and bright green. The 
species comes from Calcutta, and may be seen in the 
stove at Kew. 
H/€MANTHUS CINNABARINUS. 
The habit of this bulbous plant is similar to that of 
H. multiflorus, but the leaves are produced directly 
from the bulb, not from the side of it, and the flower 
scape which is contemporaneous with the foliage 
springs from the centre of the latter, above which it 
rises just sufficient to show the flowers quite clear of 
the leaves. The flowers are borne in dense umbels 
and the lanceolate spreading or slightly reflexed seg¬ 
ments, together with the stamens and style are of a 
bright cinnabar-red, as the specific name implies, 
and very ornamental. As the species is a native of 
the Gold Coast and Cameroon Mountains, it 
requires a stove temperature, but is altogether worthy 
of a place there. 
CANARIUM STRICTUM. 
There are some fifty species of Canarium, all of 
which are tall trees, a fact which prevents them from 
being grown in the stoves of this country. They are 
permeated with a balsamiferous resin of some 
economic importance, and the species under notice 
is known as the Black Dammar. A specimen in the 
economic house at Kew is 10 ft. high, and the large 
pinnate leaves consist of eleven to thirteen oblong- 
elliptic, serrated leaflets of some ornamental value. 
The young stem and leaves are, however, highly 
attractive. The former is velvety crimson, and the 
older of half-a-dozen leaves are of a rich bronzy-red, 
while the younger ones are of a rich crimson. The 
matured leaves are of course green. Small speci¬ 
mens would be highly appreciated in the stove for 
the sake of their foliage. 
THE CHINESE PAGODA TREE. 
Seeing that Sophora japonica is a native both of 
China and Japan, the popular name may with equal 
propriety be Chinese or Japanese Pagoda-tree. It 
was first introduced to Britain from China in 1763, 
and, considering the length of time it has been in this 
country and its hardiness, one is inclined to ask why 
it has never become more popular than it is. The 
leaves are pinnate, somewhat resembling those of a 
Robinia, but they are smaller, more leathery (giving 
one the impression that they are evergreen), and of 
an intense dark-green colour. The pea-shaped 
flowers are pure white, and produced in the greatest 
abundance in panicles terminating the shoots, so that 
when in bloom the effect is handsome during August 
and September, till cold weather or frosts cause the 
flowers to drop. The tree is very late in coming 
into leaf in the spring, in fact, one of the latest, and 
the leaves retain their rich, dark hue till frost causes 
them to fall. Why such a tree should so seldom be 
seen in British collections is a mystery which is 
difficult of explanation. 
SOLANDRA GRANDIPLORA. 
Popularly this is known as the Peach-coloured 
Trumpet Flower, and is a native of tropical America. 
It therefore requires a stove temperature to grow and 
flower it properly, and being of the nature of a tall 
climber plenty cf houseroom must be given it, 
otherwise years may elapse without ever a flower 
being produced. The latter is trumpet-shaped and 
buff-yellow, with ten brownish-burple bands in the 
throat (that is, one opposite each segment and one 
between). One to six of these flowers are produced 
in a cluster terminating the shoots, but an axillary 
shoot is soon developed, making the flowers appear 
lateral, as occurs in many other members of the 
Solanum family. The corolla is drooping with a 
five-lobed, undulated, and crenate lamina, and may 
be compared to that of a Brugmansia, but the tube 
is shorter and narrower, while the lamina is rela¬ 
tively wider. A dry stove temperature suits it very 
well, as may be seen in the succulent house at Kew. 
TUBEROUS BEGONIA MRS. B R. DAVIS. 
This superb new double variety received a Certificate 
at Shrewsbury, and was in a stand of very fine blooms 
exhibited by Mr. B. R. Davis, of Yeovil. Its form is 
that of a beautiful Camellia imbricata, and as large, 
of very fine substance, and of a bluish-white colour, 
margined with bright light pink. It is a complete 
walk-away from any others seen at the Midland and 
Northern Shows this year, but cannot be sent out for 
at least a couple of years. — W. D. 
ORCHID NOTES AND GLEANINGS. 
Orchid Growers' Calendar. 
Many of the plants now completing their growth 
will require careful attention as to watering. As the 
pseudobulbs reach maturity less water will be re¬ 
quired. Plants of Dendrobium chrysotoxum, 
D. suavissimum, &c., having completed their 
growth should be removed to a cooler house where 
the plants can get more air, which will assist them 
to mature their pseudobulbs, and ensure their 
flowering freely when introduced into heat later on. 
Masdevallias of the Harryana and ignea type may 
be seen to and potted if required. Large specimens are 
apt to decay in the centre. Where this is the case 
the plants should be carefully divided into pieces and 
repotted, using peat and sphagnum with a few pieces 
of charcoal added. The pots should be well drained, 
and the plants kept well up above the rim of the 
pot. Although the Masdevallias are essentially 
cool house Orchids, they should not be kept too cold 
during the autumn and^winter months, or the plants 
are liable to be damagecj by " spot ” on the leaves, a 
troublesome complaint to get rid off. Keep the 
plants close and a little warmer for a week or ten 
days after repotting. 
Oncidium flexosum may also be repotted where 
necessary. This plant is very effective for arranging 
with others when grown with single leads in 48's or 
32’s. The flower spikes when so treated become 
larger, with a greater quantity of flowers. This 
Orchid delights in plenty of heat and moisture when 
making its growth, and the usual mixture of peat 
and sphagnum will suit it to grow in. Oncidium 
sarcodes may also be repotted; remove all the old 
material that can be had without injury to the roots, 
and repot in fresh peat, sphagnum and charcoal. 
This plant should be kept in the warm house while 
making its growth, and the plant rested for some 
time after flowering. When well flowered this 
makes a telling object when arranged with others, 
lasting about three weeks in flower. 
Cattleyas should have plenty of water while 
making their growth, but from those having their 
growths nearly completed the water should be some¬ 
what withheld.— A. W. 
Habenaria carnea. 
The genus to which our native Butterfly Orchis 
belongs is a very large one, and the plant under 
notice is quite distinct in its way. The leaves are 
lanceolate-oblong, olive-green and thickly spotted 
with white, reminding one of an Anaectochilus or 
Goodyera more than a Habenaria. They are borne 
in a radical rosette lying upon the soil, while a few 
bracts clasp the otherwise leafless stem. The scape 
is 6 in. or 8 in. high, bearing a short spike of flowers 
of large size for the genus and quite showy. The 
upper sepal is small, hooded, three-nerved, and of a 
deep flesh-colour; the lateral sepals are obliquely 
ovate, much larger and paler. The petals are half 
ovate, small, pale, and approach one another under 
the upper sepal. The lip, on the contrary, is very 
large, deeply three-lobed, and almost white; its 
lateral lobes are broad and rounded on the outer 
edge, while the middle lobe is obversely reniform 
with a small tooth in the notch. The spur, from 
which the generic name is derived, is long, slender, 
and projects behind. Altogether it is a neat and 
pretty Orchid, well deserving of cultivation in collec¬ 
tions. As it comes from Singapore it may require 
stove treatment to grow it succesfully, but that 
remains to be proved by experiment. It has been 
flowering for some time past in the warm division of 
the Orchid house at Kew, 
Coryanthes leucocorys. 
Such is the name given to a strikingly distinct and 
new species of Coryanthes from Peru, introduced by 
Messrs. Linden, L’Horticulture International, Parc 
Leopold, Brussels, and flowered by them in June 
last. Readers will be familiar with the name Cory¬ 
anthes if not with the plant, as the Orchid with the 
large bucket into which a liquid trickles, resembling 
a dripping well, specially prepared to give its insect 
visitors a bath, gratis, and no doubt much against 
their will. The bucket is 2 in. in diameter, ij in. 
from front to back, ij in. deep, and suffused and 
marbled with rosy purple on a white ground. The 
hood is concave resembling the half of a bivalve 
shell, ivory white and overlapping the edge of the 
bucket. In this latter respect it differs from other 
species which have yet found their way into cul¬ 
tivation. The dorsal sepal is very large, suborbicular 
and striped and suffused with brownish-purple on a 
pale yellowish-green ground ; the lateral sepals are 
curiously shaped organs, more than 4 in. long, 2 in. 
broad, and yellowish green striped and blotched 
with brownish-purple. The petals are falcate, and 
very narrow, but 2 J in. long, and white, variously 
suffused and marked with purple. The pseudobulbs 
are oblong-ovoid, ii in. to 2J in. long, ribbed and sur¬ 
mounted by lanceolate leaves similar to those of a 
Stanhopea. The pendulous scape bears one or two 
huge flowers. There is a coloured figure of the 
species in Lindenia, pi. 293. 
Sobralia leucoxantha. 
This plant will flower when only about 12 in. high, 
but a specimen exhibited by Messrs. Seeger & 
Tropp, Lordship Lane, East Dulwich, at the Drill 
Hall on the 25th ult., had slender stems 3 ft. or 4 ft. 
high, and furnished with lanceolate-elliptic, strongly 
plaited or ribbed, dark green leaves. The sepals are 
oblong, the petals broader, and all are revolute at 
the tips and pure white. The lip is the striking 
feature of the flower and stands out boldly : the 
tubular or convolute portion is white, while the 
lamina is much crisped and golden jellow passing 
into orange in the throat and white at the margin. 
The species is a native of Costa Rica. An Award of 
Merit was granted it.
