ORCHID NOTES AND GLEANINGS. 
By John Fraser, F.L.S., Kew. 
The undermentioned Orchids were certificated at 
the meeting of the Royal Horticultural Society on 
the 12th inst. 
Dendnobium Griffithianum Guibertii. 
The first plant of this variety appeared in the collec¬ 
tion of an amateur named M. Guibert, of Paris, in 
1876, and was supposed to be the only specimen ever 
introduced. It is therefore remarkably rare. The 
stems are somewhat club-shaped, square, two to 
three jointed, 10 in. long, and suddenly narrowed 
into a sort of stalk at the base. They are sur¬ 
mounted by two or three elliptic leathery leaves of a 
dark green hue. The raceme of bloom is drooping 
from near the top of the stem and bears a large 
number of flowers. The clear yellow sepals are 
ovate; and the petals are much broader, nearly 
orbicular, concave, and similar in hue. The lip is 
orbicular, finely and densely pubescent, emarginate, 
shallowly fringed at the margin, and of a deep almost 
golden-yellow. It differs from the type in having 
the stems more tapered at the base, the leaves more 
leathery, and the racemes longer with larger and 
brighter flowers. It is certainly handsome. First- 
class Certificate. Exhibited by Messrs. F. Sander 
& Co., St. Albans. 
Epidendrum alatum. 
The pseudo-bulbs of this are ovoid, 2 in. to 3 in. 
long, and bear two or three strap-shaped leathery 
leaves about 10 in. long. The scape is 3 ft. long, 
with a panicle of flowers towards the top. Both 
sepals and petals are spathulate and brown, with 
darker veins and a yellow edge. The lip is three- 
lobed, with the lateral lobes obovate, yellow and 
remarkably large for the genus ; the middle lobe is 
reflexed at the sides, yellow, and lined with deep 
brown on the upper two-thirds. Botanical Certifi¬ 
cate. Exhibited by Messrs. F. Sander & Co., St. 
Albans. 
Cattleya Mossiae Mrs. R. H. Measures, 
Nov. var. 
The sepals and petals of this beautiful variety are of 
a delicate blush. The tube of the lip is of the same 
hue, but the much undulated and crisped lamina is 
white with a large purple blotch in the centre. 
There is a pale yellow transverse band joined at an 
angle in the throat, while the interior of the tube is 
lined with white or pale yellow on a purple ground. 
Odontoglossum crispum mirabile, Nov. var. 
The sepals of this strange and beautiful variety, if it 
be a variety of O. crispum at all, are lanceolate and 
white, with one or two very broad and rich brown 
blotches across the middle, covering a great part of 
them. The petals are ovate, acute, revolute at the 
tip, and white with one large brown or chocolate 
blotch above the middle, and one or two minute ones 
below it. The lip is rich chocolate with a yellow 
disc and crest, and is white at the very base and 
tip. Award of Merit. Exhibited by Baron 
Schroder (gardener, Mr. H. .Ballantine), The Dell, 
Egham. 
Odontoglossum crispum Baroness Schroder, 
Nov. var. 
Here again we have a most remarkable variety 
with regard to colour and markings. The sepals are 
lanceolate, and for want of a better definition we 
describe them as of a rich brownish-purple and rosy 
at the base and tip. The petals are ovate, acuminate, 
shallowly toothed, and rich brownish-purple with a 
white claw and a very narrow edge of the same hue. 
The lip is cordate at the base, revolute at the sides, 
and chocolate with a yellow disc, striped brown, and 
white at the tip. Nothing like it has ever appeared 
before. First-class Certificate. Exhibited by Baron 
Schroder. 
Odontoglossum crispum grande maculatum, 
Nov. var. 
The flowers in this instance are of great size with 
very much imbricated segments and beautiful mark¬ 
ings. The sepals are ovate, almost rhomboid, very 
broad, white with a few brownish-purple spots on 
the centre; the back of them is heavily banded with 
purple shining through upon the face. The petals 
are triangular ovate, and white with very numerous, 
orbicular, rich, tawny-brown spots nearly all over 
them. The lip is white with a blotch in front of the 
yellow disc and crest. All the three varieties are 
most probably unique. First-class Certificate.

Masdevallia glaphyrantha, Nov. hyb. 
The seed parent of this hybrid was M. infracta, and 
was crossed with the pollen of M. Barlaeana. The 
tube of the flower is very short, yellow on the ribs, 
and purple between. The upper sepal is short, 
triangular, or nearly orbicular, and purple with a 
crimson tail about 2 in. long. The lateral sepals are 
short, connate for three-parts of their length, and 
dark, rich purple with deeper veins; the brownish- 
crimson tails are ij in. long. Award of Merit. 
Exhibited by Messrs. J. Veitch & Sons, Chelsea. 
Masdevallia Parlatoreana, Nov. hyb. 
The hybrid in this case was derived from M. Barleana 
crossed with M. Veitchiana, and has many of the 
characters and the fine appearance of the latter. 
The tube of the flower is crimson and paler beneath. 
The upper sepal is triangular, orange, and covered 
with a violet-plush ; the lateral sepals are oval, and 
similar in colour; their tails are i in. to ij in. long, 
and crimson. The small petals are pale yellow. 
Award of Merit. Exhibited by Messrs. J. Veitch & 
Sons. 
Masdevallia Asmodia, Nov. hyb. 
M. Chelsoni was the seed parent of this hybrid, 
and the pollen parent was M. Normanil. The tube 
is of medium length and dull red. The triangular, 
upper sepal is pale yellow, with three darker lines and 
a deep dull crimson tail about 3 in. long ; the lateral 
sepals are obliquely ovate, dull rose mixed with 
yellow, and having deep purple veins ; their tails are 
brownish-crimson and 2J in. long. Award of 
Merit. Exhibited by Messrs. J. Veitch & Sons. 
Aerides Maculosum Schroder!, Nov. var. 
The sepals and petals of this beautiful variety are 
elliptic and pale pink spotted with purple. The lip 
is oblong, three-lobed, reflexed at the sides, and deep 
purple ; the lateral lobes are small and white, dotted 
with purple. The variety differs from the type in 
having more richly-coloured flowers with a greater 
profusion of purple spots. First-class Certificate.

Mr. W. H. White), Burford Lodge, Dorking. 
Prominea microptera, Nov. sp. 
As FAR as we are aware this is new to cultivation. 
The sepals and petals are lanceolate and pale green. 
The lip is three-lobed, the lateral lobes are white and 
striped purple, while the middle lobe is ovate and 
greenish-white with two broad brown bars. It is a 
dwarf and small-growing plant suitable for culture 
suspended in small pans. Botanical Certificate.

Bulbophyllum barbigeptim. 
The sepals of this remarkable Orchid are deep pur¬ 
ple. The spreading and resupinate lip oscillates 
with the slightest breath of wind, and is covered 
with a yellow tomentum and furnished at the tip 
with a heavy beard of long, slender purple hairs that 
wave to and fro in a very peculiar manner when 
agitated by the wind. The small, roundish pseudo¬ 
bulbs are furnished with one oblong leaf. Botanical 
Certificate. Exhibited by Sir Trevor Lawrence, 
Bart.

very choice. That under notice is pure white with 
exception of an orange blotch in the throat. First- 
class Certificate. Exhibited by H. T. Pitt, Esq., 
Stoke Newington. 
Odontoglossum crispum Miss Florence M. 
Bovill, Nov. var. 
The flowers of this very choice form are large, and 
round with imbricated segments. Both sepals and 
petals are spotted with rich, purplish-red and beauti¬ 
fully suffused with rose in such a characteristic way 
that renders them very distinct. Award of Merit.

large and very characteristic flowers. The sepals 
and petals are of a uniform creamy colour while the 
lip is a .soft mauve hue. Award of Merit. Exhibited 
by De B. Crawshay, Esq. 
Houlletia Lansbergii. 
The flowers of this species are almost white and 
therefore much paler than those of this genus usually 
are. All the segments are incurved, making the 
flower concave. The curious lip has very narrow or 
linear lateral segments. Botanical Certificate.

The Orch’d Growers' Calendar. 
Insects. — Cleanliness being such an important 
factor in the successful culture of Orchids, too much 
attention cannot possibly be given to the thorough 
eradication of insects. Hitherto we have gone on in 
the old sweet (?) way of fumigating the houses with 
Tobacco paper, but this mode, although effective, is 
unpleasant and injurious to those who have to re¬ 
main in the houses until they are well filled with 
smoke. This is necessary to prevent the paper 
flaring, which it is sure to do if left to burn out with¬ 
out attention. In addition, it is necessary to remove 
all plants that are in bloom to some other structure 
whilst the house is being fumigated. With the new 
vaporizing fumigator all this inconvenience is avoided. 
As a rule we are not in a hurry to try new remedies, 
but after reading the favourable'remarks on p. 647 of 
your issue of June gtb, w^e decided to give Mr. 
Richards' vaporiser a trial. Two of the vaporisers 
were placed in the Cattleya house, which has about 
4,oco cubic feet of space, and to secure a reliable 
trial a few plants badly infested with aphis were in¬ 
troduced. On examination afterwards the aphis 
was found to be quite dead, in fact, nothing in the 
way of aphis or thrips could be found with any life 
in them, so effectually had it done its work. Neither 
flowers nor young Fern fronds appear to be in the 
least affected by the vapor. 
Odontoglossum citrosmum. —As this beautiful 
Orchid goes out of bloom it should be re-basketed 
or re-panned as the case may be. We grow some in 
each kind of receptable, which are hung up close to 
the glass in the Cattleya house. Peat, sphagnum 
moss and bits of croCKS mixed grows them excellently. 
It is not unusual when well looked after for them to 
make branching spikes, and we think it much the 
best with these plants to afford them a shift every 
season, as, owing to the long rest they are subjected 
to after the growth is made up until the flower 
spikes are in sight, causes the sphagnum to die. 
Cool House.— Oncidium macranthum, now flower¬ 
ing and pushing spikes, must be well supplied with 
moisture at the roots ; in fact, they never should be 
allowed to get really dry. Thrips are very partial 
to this Oncidium, and must be kept under, or the 
foliage will soon become disfigured and the plants 
weakened ; but if the atmosphere (as it should be) 
is kept well charged with moisture, they will not be 
very troublesome. 
Syringing. —Keep the syringe well going in all 
divisions during bright days, so as to induce the 
plants to make good, strong growths. If done 
thoroughly the Odontoglossums will require very 
little water other than what is supplied through the 
syringe. It is, however, advisable to look over them 
twice a week with a water pot, as those at the back 
may be dry.— C.
