spur. The lip is very small, as in other species ; and 
the small, pale purple petals lying alongside of the 
column are included in the hood. It is a native of the 
Cape, between Cape Town and Port Elizabeth, on the 
same spots as the rare D. venosa, which seems to be 
undergoing extinction by it. A plant was exhibited 
by Mr. James O’Brien, Harrow-on-the-Hill, at the 
Royal Botanic Society’s show on the 14th inst., and 
was awarded a Botanical Certificate. 
Cypripedium Elliottianum. 
The upper sepal of this Cypripedium, as exhibited 
by Messrs. Hugh Low & Co., Clapton, at the Royal 
Botanic Society’s show on the 14th inst., was broadly 
ovate, acute, and marked by numerous parallel deep 
brown stripes on a yellow ground. The lower sepal is 
similar, but narrower. The ground colour of the long, 
linear-lanceolate, declining petals is also yellow, spotted 
with brown markings along the course of the veins on 
the lower half, and striped with the same hue on the 
apical half. The large lip is heavily suffused with 
brown, with darker veins. The ligulate, heeled leaves 
are bright green. A Botanical Certificate was awarded 
to it. 
Cattleya Mendelii albens. 
The sepals are oblong, and, like the petals, are white. 
The latter are broadly ovate, and crisped at the margin. 
The lip is also white, with the exception of a faint 
purple blotch on the disc of the lamina and a pale 
yellow one in the throat ; the lamina is beautifully 
crisped along the edges. The plant was exhibited at 
the Royal Botanic Society’s show on the 14th inst. 
by Mr. G. T. White, Drayton Villa, Winchmore 
Hill, who received a Botanical Certificate for it. 
Cymbidium ALBUC/EFLORUM. 
By an oversight, in our report of the last meeting of 
the Floral Committee of the Royal Horticultural 
Society, the exhibition of a flowering specimen of this 
plant was attributed to M. Linden, instead of to Mr. 
G. Burnham, 17, Paget Road, Stoke Newington, N. 
Mystacidium filicorne. 
I should be glad if some reader who has successfully 
grown this Orchid would give me a little information 
as to the best way of treating it.— It. H., Leeds.

SEASONABLE WORK IN THE 
GARDEN. 
Gf.sneras and Ttdzeas.— The late batches of these 
should now receive attention, for the tubers will be 
starting, and the young shoots if not thoroughly exposed 
to light will suffer by becoming drawn and weakened. 
If still in the old soil and started into growth, the 
plants should receive a good watering to make them 
part freely from the old soil. Re-pot the Gesneras in a 
rich light soil and give the Tydseas a little more loam. 
Gloxinias. —Keep the spring sown seedlings growing 
on rapidly by re-potting as they require it, giving the 
plants the advantage of plenty of heat and moisture, 
with a good exposure to light, shading, however, in the 
hotter parts of the day. The more forward of the 
earliest sown batch should be fit to put in their flowering 
pots. 
Lachenalias. —The plants that flowered recently 
should not be rapidly ripened off by the entire with¬ 
holding of water, but should be regularly attended to 
in that respect until the leaves gradually die away and 
become yellow, when water may with propriety be 
stopped. 
Chrysanthemums. —Late kinds, if they are intended 
to be headed down in order to keep them dwarf for the 
November exhibitions, should now have the operation 
performed. Early flowering kinds, on the other hand, 
may be left for another fortnight before being cut back, 
as they sooner reach the flowering stage. Stand the 
plants on a bed of ashes in a situation sheltered from 
north and east winds. 
Dahlias. — Late-struck cuttings should be kept 
growing freely in frames kept rather close. Those that 
are of some size, and in 5-in. or 6-in. pots, should be 
kept by themselves and freely ventilated during the 
day after the roots have taken to the fresh soil in re¬ 
potting ; in fact, the sashes may be entirely taken off 
with advantage. Leave plenty of space between each 
plant, so that light and air may freely reach all the 
foliage. 
Gladioli. —Corms that have been potted up and 
started under glass to forward them should be turned 
out of the pots, and planted where they are intended to 
flower, without further delay. Give a good watering 
after planting to settle the soil, and should the weather 
prove dry later on, the operation may be repeated to 
great advantage. 
Hollyhocks. —Where strong stems are desired for 
exhibition or otherwise, the small shoots should be 
cut away to concentrate the energies of the plant upon 
one stem alone. This should be secured to a stout 
stake as it advances. Where a large quantity of 
flowers is desired simply for ordinary garden decoration, 
three or four stems may be allowed from old stools and 
secured to stakes. 
Succulents for Carpet Beds. —Now that Hya¬ 
cinths and Tulips are over, they may be lifted, and the 
summer bedding commenced in earnest. Where a 
large amount of carpet bedding is done, the beds should 
be prepared, the designs drawn out, and the planting 
of Sedums, Echeverias, Kleinias, and Sempervivums 
proceeded with. Echeveria secunda glauca and other 
allied kinds are perfectly safe from late frosts now. 
Hardy Subjects for Carpet Bedding. — Such 
things as Herniaria glabra, Mentha Pulegium gibral- 
tarica, Thymus lanuginosus, Sedum lydium, S. glaucum, 
S. brachyphyllum, crustaceous Saxifrages, including 
S. aizoon, S. Hostii, S. valdensis, and others of that 
type, furnish a long list of plants that may with 
propriety he used for the groundwork of beds. All 
are perfectly hardy, and easily kept in the reserve 
garden during winter should it be necessary to remove 
them from the beds during that season for the planting 
of spring-bedding stuff. 
Teaches. —When the fruits in the earliest house 
have safely passed the stoning period they may be 
urged to make their second swelling, by giving more 
artificial heat at night, by allowing the temperature to 
rise higher during the day, and by closing earlier in the 
afternoon to economise fuel. Syringe freely and damp 
down when closing, in order to keep insect pests in 
check. 
Early Vinery. —Red-spider and thrip are liable to 
obtain a footing during the ripening period of the fruit, 
owing to the maintenance of a dry atmosphere. Paint 
the hot-water pipes with sulphur to keep down spider, 
and fumigate lightly on two or more successive nights 
in order to keep thrip under control till the fruit is cut. 
Figs. —Syringing must be stopped when the plants 
are carrying ripe fruits, but, in order not to starve or 
check the vigour of the plants, plenty of liquid food 
should be applied at the roots. Damping down the 
paths and borders will also tend largely to prevent the 
increase of red-spider and scale. Ventilate freely to 
secure a free circulation of air. 
Kitchen Garden. —Great advantage will accrue to 
the different crops by keeping the hoe constantly at 
work, stirring the surface soil as well as destroying 
the weeds. A great deal ot watering can be saved by 
thus keeping the surface soil loose, when the plants 
will respond by making a more rapid growth. When¬ 
ever the young plants of such things as Savoys, Brussels 
Sprouts, Broccoli, and others intended for winter use 
are ready for transplanting, no opportunity should be 
lost of having the operation performed after a shower 
of rain.

ROYAL AQUARIUM SHOW. 
The early summer exhibition, opened on Wednesday, 
was somewhat novel in character, and rather differently 
arranged from the shows that have previously been 
held at the Aquarium. Roses, Azaleas, hardy her¬ 
baceous plants, including Pansies, Irises, Pyrethrums, 
Daffodils, also Calceolarias, Gloxinias, and miscellaneous 
greenhouse plants made up the bulk of the flowering 
subjects. Amongst the non-flowering, Caladiums were 
a great feature. Messrs. John Laing & Sons, Forest 
Hill, took the first prize for a group of flowering 
and foliage plants arranged for effect. The Palms, 
Dracaenas, Ferns, and Caladiums were brightened 
up with Orchids and Heaths. Mr. H. James was 
second with a mixed lot of plants ; he, however, took 
the first prize for Ferns and eight greenhouse Azaleas. 
Mr. C. Turner, Slough, was second for Azaleas. Messrs. 
J. Laing & Sons took the first prize for Caladiums with 
nine specimens about a yard in height and as far 
through. Mr. J. Day, gardener to W. S. Gover, Esq., 
Casino House, Herne Hill, took the second prize with 
smaller but well-coloured specimens. Mr. C. Turner 
took the prizes in both classes of Pelargoniums with 
well-flowered examples, especially of the fancy kinds. 
The first prize for a group of hardy cut flowers arranged 
for effect was awarded to Mr. T. S. Ware, Tottenham ; 
Messrs. Paul & Son being second, and Messrs. Barr & 
Son, third. The groups consisted of Irises, Pieonies, 
Daffodils, Pyrethrums, Azaleas and Lilac. These 
different kinds were arranged in bunches with their own 
foliage. Mr. C. Nunn, gardener to J. Soames, Esq., 
Maze Hill, Greenwich Park, took the first prize for 
Gloxinias in the open class, and also the first prize 
offered for that class of plants by Messrs. Sutton 
& Sons. Mr. J. Lambert, gardener to II. W. Segelcke, 
Esq., Herne Hill, had the best Gloxinias in the 
amateurs’ class. Mr. R. Dean, Ealing, was awarded 
the first prize for show Pansies in pots ; they were well 
flowered. Mr. F. Hooper, Widcombe Hill, Bath, had 
the best fancy Pansies in pots. Messrs. Paul & Son 
were first for Violas, Mr. C. Turner was second, and 
Mr. R. Dean was third. In the miscellaneous class a 
collection of fancy Pansies was shown by Messrs. 
Ryder & Son, Sale, Manchester. Mr. R. Dean showed 
a nice lot of Poppies, Stocks and other hardy subjects. 
A collection of Roses in pots and also cut flowers was 
shown by Messrs. W. Paul & Son.

QUESTIONS AND ANSWERS. 
Black-fly on Ivy. — W. M. C.: A wash made of soft-soap 
dissolved at the rate of 4 ozs to the gallon, and a little tobacco- 
water, will be found very effectual. Syringe the plants in the 
evening, and wash with clear water the next morning. We 
tried the “ Demon" Insecticide in a similar case last week, and 
with the best results. 
Brussels Sprouts, &c., Diseased.— M. M., Aberdeen: Your 
seedlings of Brussels Sprouts, Cauliflower, and Broccoli are 
affected with a fungus known as the White Rust (Cystopus 
candidus). It is the same which attacks the Shepherd's Purse 
and many other Cruciferous weeds, as well as the Cabbage tribe 
generally. The disease cannot be cured after it has thoroughly 
taken possession, as it ramifies in the intercellular tissues of the 
stems, leaves, or fruits, according to the part attacked. Your 
best plan would be to root out and burn all plants badly affected, 
and remove the leaves in other cases where the attack is less 
severe, and treat them in the same way, in order to check the 
increase of the fungus. Shepherd’s Purse or other Cruciferous 
weeds growing with or in the neighbourhood of your plants 
should also be rooted up and burnt. Perhaps a dusting of sulphur 
would prevent the spreading of the spores produced on the 
surface of stems and leaves ; but it would not kill that part of 
the fungus in the interior of the plants. 
Cucumbers Diseased. — Devonian: Your Cucumbers must be 
in a very sorry plight if they are all as bad as those you sent us. 
The sunk spots and patches on the surface of the fruits are 
densely covered with what is called the Mildew of Cucumbers 
(Polyactis vulgaris); but although that assists in causing a more 
rapid rotting of the fruits, it is only able to live there because of 
the presence of another fuDgus—namely, Glceosporium laeticolor, 
which lives in the interior of the fruits. Both kinds of fungi 
are now making rapid progress in their work of destruction. 
All diseased fruits should be removed and destroyed at once by 
burning them. The progress of the disease would also be con¬ 
siderably held in check if you maintain a drier atmosphere and 
give plenty of ventilation. This would not only be inimicable 
to the fungus, but harden the plants and make them more 
disease-resisting. 
Names of Plants. — J. Potten: White—Saxifraga granulata 
flore pleno. Pink—Cardamine pratensis flore pleno. Both 
British. James Hay; 1, Maxillaria arachnites; 2, Maxillaria 
tenuifolia ; 3, Miltonia flavescens ; 4, Clerodendron Thomsons. 
JV. J. D.: The flowers are those of Leucojum aestivum; the 
leaves belong to Narcissus poeticus recurvus. IF. L.: I, Clivia 
(Himantophyllum), miniatum var. ; 2, Dieffenbachia regina, or 
closely similar to it; 3, Howea Forsteriana, generally known as 
Kentia Forsteriana in gardens; 4, 'Asplenium bulbiferum ; 5, 
Asplenium flaccidum ; 6, Epipliyllum truncatum. 
Smokeless Coal. — A. AT, K. : The nearest approach to smoke¬ 
less coal is Anthracite, obtained in the South Wales coalfields, 
and this is extensively used now in gardening establishments on 
account of its heat-giving properties, economy of labour in 
stoking, and extremely little smoke production. For further 
information on the subject, write to Mr. W. II. Essery, Colliery 
Office, Swansea.
