ORCHID NOTES AND GLEANINGS. 
Orchids from Terregles, Dumfries. 
A box containing some fine varieties of Orchids, and good 
examples of what cultivation can do, reached us last 
week from the late Captain Maxwell’s gardener, at 
Terregles, Dumfries, Mr. Chalmers. There were 
two flowers of Cattleya Mendelii, both with a hand¬ 
somely coloured lip, but one was of surprising size and 
beauty. The tube and the side lobes of the lip were 
white, as well as the usual white blotches so character¬ 
istic of this Cattleya. A flower of C. Trianee Schroderre 
was equally notable for size. The sepals and petals 
were of the usual pale lilac, but on the margins of the 
orbicular, bilobed lamina of the lip the colouring was 
distinctly intensified, forming a beautiful border. The 
large orange-yellow blotch in the throat was particularly 
characteristic. Accompanying them were some flowers 
of Dendrobium infundibulum, measuring 4 ins. across 
the petals, and showing the effects of good cultivation. 
There was also a raceme of Oncidium serratum, taken 
from a plant with over 100 flowers upon it; and inflor¬ 
escences of Odontoglossum triumphans, a fine dark 
variety, and of 0. sceptrum, richly coloured, and in 
characteristic form. 
Oncidium maculatum. 
Lindley originally described this under the name of 
Cyrtochilum maculatum, and a few other species were 
also added to the genus. Structurally the flowers of the 
plant under notice present as much affinity with Odonto¬ 
glossum as with Oncidium. This is most observable 
in the form and insertion of the lip, the claw of which 
does not proceed at right angles from the column as in 
a true Oncidium, but ascends for a short distance as in 
Odontoglossum hastilabium, O. citrosmum, and some 
othei'3. The sepals and petals were originally described 
as green spotted with purple, but there are many 
variations amongst specimens that have been imported 
from time to time since the days of Lindley. Several 
of the more important of them have received distinctive 
names. There are some specimens at Devcnhurst, 
Chiswick, showing variation in colour, and the sepals 
and petals are heavily blotched with dark brownish 
purple. The lip is much paler and almost white ; it is 
ovate in outline, pointed, and therefore widely distinct 
from a typical Oncidium, which has a three-lobed lip 
with a large, obreniform, terminal lobe. 
Dendrobium Williamsoni. 
In habit of growth this closely resembles that of D. 
Draconis, to which it is undoubtedly allied. The erect 
stems are about 1 ft. in height, and bear a number of 
flowers at their apex, the sepals and petals of which are 
pale yellow or nearly white, and more or less tinted 
with a fuscous brown. The lip is white with a large 
orange-scarlet blotch on the disc, where also it is 
heavily bearded with hairs of the same colour or a 
little paler. It is a native of Assam, from whence it 
was introduced in 1869, but as it has proved rather 
difficult of cultivation it has never become very 
common. But the same applied to D. formosum, D. 
Draconis and others until the treatment they required 
became better known. It flowered recently in the 
Orchid house at Kew. 
Miltonia Roezlii. 
Asa species this is closely allied to M. vexillaria, and 
both are best recognised under the name of 
Odontoglossum, though why they should ever receive 
that name is not very clear on botanical grounds. 
The sepals and petals of the plant under notice are 
longer and more attenuated at the apex than those of 
M. vexillaria, and this is one of the chief points of 
distinguishing the two, although the foliage is also 
slightly different. It is, however, readily recognised 
by horticulturists by means of the dark vinous-purple 
blotch at the base of the pearly white petals. The large, 
flat, bilobed lip is white, with exception of a few 
radiating yellow lines near the base in front of the 
crest. The odour of this species may be compared to 
that of the China Rose. A large-flowered specimen is 
now in bloom in the gardens at De'vo'nhurst, Chiswick. 
Burlingtonia fragrans. 
The flowers of this charming little Orchid are produced 
in erect racemes from amongst the rigid dark green 
leaves. The sepals and petals are white, or the former 
may be tinted with pink externally. The lip is of 
large size, and white tinted with yellow down the 
centre. The flowers last three or four weeks in 
perfection if kept in a dry atmosphere, and have a 
delicious odour resembling that of Hawthorn. The 
plant is admirably adapted for basket work, and should 
be suspended near the glass. It is flowering in the 
cool Orchid house at Kew.

ODONTOGLOSSUM HORSMANII. 
The late Professor Reichenbach described this Odonto¬ 
glossum as a new species, but he added “ potius 
hybrid,” meaning a hybrid rather. An examination of 
the flower shows points of an intermediate character 
between 0. Pescatorei and 0. luteo-purpureum, or some 
form of it, such as 0. l.-p. sceptrum, of which it 
possesses the size and rounded outline. The lip is 
obscurely pandurate, short, auricled at the base, 
rounded at the apex, and much curled or crisped, 
hiding the minute recurved tip, very finely and shortly 
fringed at the margin, white with a yellow disc, three 
or more cinnamon-brown blotches of moderate size in 
front of it, and several smaller ones around the sides. 
There is also a line of faint brown spots around the 
margin of the lamina ; but this character is common to 
varieties of 0. crispum, 0. Pescatorei, and 0. luteo- 
Odontoglossum Horsmanii. 
purpureum sceptrum. The crest consists of two 
diverging, slightly-toothed lamella;, with a shorter 
ridge between their bases, and a bifid tooth on each 
side. The lamellae and teeth are yellow, with radiating 
orange lines running down the claw. The crest and 
the lip—especially the former—points to 0. Pescatorei ; 
but neither are identical with the latter. The lanceo¬ 
late-elliptic sepals are incurved, wavy at the margin, 
with three cinnamon blotches on a ground of the palest 
sulphur. The rhomboid-elliptic petals are also in¬ 
curved, and again recurved at the tip, much undulated 
at the sides, and crenate at the edges, with a few larger 
teeth at the widest part, a little below the middle. 
When fresh, the ground-colour is white, with several 
large cinnamon blotches above the middle, and numerous 
small spots below it. The column is clavate, channelled 
in front against the claw of the lip, white or pale 
sulphur upwards, with a few brown blotches behind 
near the top. The wings are obliquely sauarish, shortly 
toothed at the edge, with the uppermost teeth longer, 
but not fringed, and white with a row of brown spots. 
These characters of the column again point to 0. 
Pescatorei, but they may be only coincidental, just as 
allied species may have characters in common by which 
they may be classified in groups. It is perfectly distinct 
from either of the supposed parents, and cannot strictly 
be said to belong to any of them. For garden purposes 
it is certainly of great ornamental value, and anything 
but common, if not rare. Our illustration was taken 
from a plant in the collection of H. M. Pollett, Esq., 
Fetnside, Bickley. It is a native of the hilly regions 
of Ocaha, in New Granada. 
SEASONABLE WORK IN THE 
GARDEN. 
Coleus. —Tie down the shoots into position as they 
grow and keep the plants well exposed to light to 
bring out the true colours of the foliage. A batch of 
cuttings may be struck now for conservatory decoration 
later on. A few plants dotted about on the front of the 
stages adds much to the effect of a collection of mixed 
plants. 
Basket Ferns.— Whether for conservatory or green¬ 
house work, a few of these hung about the roof does 
much to relieve the nakedness, especially of a lofty 
building. The present is a good time to transfer the 
plants to baskets, because they are now growing freely 
and would soon root into the fresh material. Several 
of the Adiantums are suitable for this work, including 
A. amabile, A. assimile, A. semulum, and A. cuneatum 
gracillimum. Larger kinds are Asplenium lucidum, A. 
flaccidum, Polypodium sub-auriculatum, Davallia Tyer- 
manni, D. elegans and D. bullata. 
Calceolarias. —The herbaceous kinds used for 
conservatory and greenhouse decoration will soon be in 
flower, as they are already in some establishments. 
Before the flowers expand they should be carefully 
examined for green-fly, and fumigated, otherwise the 
plants will get disfigured and very dirty before the 
flowering period is over. 
Liliums. —When the flower buds of such kinds as 
L. candidum, L.longiflorum Harrisii, L. auratum, and 
others make their appearance, a weak dose of liquid 
manure occasionally will greatly assist them. 
Balsams. — The earliest batch will by this time 
require a shift, and when this is done the operator 
should make a point of getting the stems as low in the 
pots as possible, to avoid legginess. Use a compost of 
moderately light, rich soil, and place the plants close to 
the glass to keep them dwarf and sturdy, at the same 
time giving ventilation freely. 
Deutzias. —When these have finished flowering will 
be a good time to thin out old, weak, and useless wood. 
This will allow a freer play of air and light upon those 
that are left, and encourage the plants to make good 
wood for next year’s flowering. Large plants in pots 
should be examined as to the state of the drainage, for 
if that is good, shifting is unnecessary, because assist¬ 
ance can be given during the flowering period by the 
application of manure-water. If potting is actually 
necessary, now is the best time to do it. 
Cyclamens.— If it is intended to save seed, the best 
varieties should be marked for this purpose, and each 
plant should only be allowed to carry but a few seed 
pods ; for by this means larger and finer seeds will be 
the result. Plants intended for flowering again in 
autumn may b; rested in a cold frame, and supplied 
with sufficient water to prevent them getting dried off 
or baked, according to the old custom. 
Vines. —The temperature in the early house, where 
the Grapes are now ripe, should be kept up to 60° at 
night, with a chink of air left on to carry off the super¬ 
fluous moisture. See that the borders are not allowed 
to get dry, otherwise the health of the foliage, a very 
important matter, cannot be maintained. Attend to 
the thinning of bunches and berries in the later houses 
in due season. 
Peaches. —The fruits in early houses should be 
exposed to all the light possible in order to colour 
them. It is difficult to get the fruits to colour so well 
as in late houses. Tie down all loose shoots therefore, 
and turn aside leaves which obstruct the light, and on 
front trellises the shoots carrying fruit should be raised 
above the wires in order to get a maximum of exposure. 
Oranges. —Where the fruits are swelling, plenty of 
heat and moisture will constitute the principal require¬ 
ments. Syringe and damp down freely, and close the 
ventilators early in the afternoon to economise sun 
heat. 
Beet and Carrots. —The earliest sowing is now 
well through the ground, and the plants should be 
thinned in due season before they become crowded. 
The main crop may now be sown, and will have plenty 
of time to attain full size. Formerly it was a custom 
to sow too early, and the roots always grew to such a 
size as to be unfit for table. A sowing of Carrots may 
still be made, if necessary, to come into use late in 
summer. 
Tomatos. —Plants intended for covering spare places 
on walls should now be put in cool, ventilated houses, 
in order to harden them off, and give that sturdiness 
necessary to prepare them for the change. By such 
means they will not suffer that check to their growth 
which unprepared plants with soft and watery tissues 
would.
