history. A great quantity of a variety of the common 
Colt’s-foot is grown for the sake of its broad creamy 
white margined foliage, used in decorative work. 
Amongst the bulbous plants, we noticed Crinum 
Maeowani, a species from Natal, usually considered 
only half-hardy, but which is now throwing up a 
vigorous flower-stem, after having braved the English 
climate for the last two years in the open air. More 
praise must be accorded to C. Powelli, a fine hybrid 
between C. eapense (Amaryllis longifolia) and C. 
Moorei, which originated with C. B. Powell, Esq., of 
Southborough, near Tunbridge Wells. A line of 
bulbs in an open border has been blooming profusely 
for some time, and will continue to do so until late in 
the autumn, when the flowers assume a much deeper 
colour than they do in warm weather. At present 
they vary from blush to warm rose, and are conspicuous 
both for their size and number. For the history of 
this hardy Crinum, see The Gardening World, 
ol. II., p. 184, and for illustration, see p. 185. 
Tntonia croeosmaeflora and T. c. aurea, although, 
strictly speaking, not bulbs, may be noticed here on 
account of their beauty and hardiness. Named seed¬ 
lings of Gladioli—some of the Continental productions 
of Lemoine—are grown in quantity, and show, by their 
vigour, that they receive congenial treatment. Great 
variety of colouring and remarkably large flowers may 
be seen amongst them, such as Sir Trevor Lawrence, 
crimson, flaked with a darker colour; G. A. Thiers, 
carmine and yellow in ' the throat, conspicuouslv 
blotched on the lower segments ; and Lamartine, with 
very large rose and yellow flowers, also handsomely 
blotched. Grand hybrids, evidently of the Gladiolus 
purpureo-auratus types, are also very conspicuous and 
showy. -_ 
NEW PLANTS CERTIFICATED 
By the Floral Committee of the R.H.S. 
August 9 th. 
Catasetum Bungerothii. 
This is the grandest of all the Catasetums. The 
oblong-lanceolate sepals are white with a tint of straw- 
colour ; but the broader oblong-elliptic petals are 
erect and ivory-white. The huge labellum is roundly 
cordate or spoon-shaped, sharply toothed or serrated at 
the margin, ivory-white, orange at the opening of the 
shortly-conical spur, and measuring 3 ins. to 4 ins. 
across. The arching raceme bore ten of these noble 
flowers, and the lanceolate plaited leaves are numerous 
and two-ranked. The old pseudo-bulbs are oblong- 
elliptic, somewhat compressed, and marked transversely 
with the sears of the fallen leaves. The odour of the 
flowers is delicious, smelling like Aniseed—some say 
Caraway. Exhibited by Baron Schroder (gardener, Mr. 
Ballantine), The Dell, Egham. 
Saoco labium Heathii. 
This is something in the way of Rhyncostylis 
(Saccolabium) Blumei majns with regard to structure ; 
but the flowers are wholly of the purest white, with the 
exception of the small anther-cap, which is a pale 
creamy yellow. The raceme was closely furnished 
with bloom for a length of 10 ins, and was undoubtedly 
a glorious sight for Orchid-lovers. Such unstained 
purity is of rare occurrence in this or most other genera 
of Orchids. Exhibited by Baron Schroder (gardener, 
Mr. Ballantine), The Dell, Egham. 
CyPRIPEDIL'M ORPHANUM. 
The name here given was owing to the parentage of 
this fine hybrid being unknown. Most, however, 
are agreed that C. Druryi was one of them. The 
standard is short and broad, marked with green lines 
in the centre, and suffused with purple towards the 
margin on a white ground ; the oblong, blunt, slightly 
declining petals are brown, suffused with rose at the 
tip, and dilated on the upper margins. The short, but 
large lip is a fine rose colour, and the most striking and 
distinct organ of the flower. The foliage is an intense 
green, with a few darker markings. Exhibited by F. 
G. Tautz, Esq. (Mr. Cowley, gardener), Studley House, 
Hammersmith. 
Gladioli. 
William Roupell. —The flowers of this new variety 
are very open, and measure 4 ins. in diameter. They 
are of a striking bright scarlet colour, with a crimson 
mid-rib on two or three of the lower segments of the 
perianth. The whole spike has a bold and attractive 
appearance. 
Pp.ls'cess Royal. —The flowers of this variety are 
equally as large if not larger than those of the last, 
and of a pleasing soft blush colour, strikingly flaked, 
and irregularly suffused with rosy carmine. The lower 
segment of the inner series of the perianth is small and 
rose-coloured at the base. Six flowers were fully 
expanded on the spike, and eleven more were in 
various stages of development. Exhibited by Messrs. 
Kelway & Son, Langport, Somerset. 
African Marigolds. . 
Lemon Queen. —Fine flower-heads of a soft lemon- 
yellow, a variety of Tagetes ereeta, were shown, dense 
semi-globular masses 44 ins. in diameter. The florets 
are somewhat undulated, and on the whole present a 
fine appearance, the beau ideal of the florist. 
Prince oe Orange. —The specimens exhibited under 
this name were equally as fine as the last, orange- 
coloured, and, if anything, the flower-heads of the 
best samples were a trifle larger. Exhibited by 
Messrs. Dobbie & Co., Rothesay, N. B. 
Rose, Single 'White Perpetual. 
The foliage of this new single Rose is ample, with deep 
green, ovate, serrated leaflets. The sepals are slightly 
pinnatifid or almost entire and globular, supporting 
five petals that are white, or frequently of a faint blush 
colour ; and the flowers have the further recommenda¬ 
tion of being freely produced and sweet-scented. Ex¬ 
hibited by Messrs. Paul & Son, Cheshunt. 
Gaillardia, "William Kelway. 
The flower-heads of this fine variety are 4 ins. to 
44 ins. in diameter, and look very distinct. The 
wedge-shaped, trifid florets of the ray are so intensely 
reddish crimson as almost to appear blood-red, and 
have small yellow tips. The disk florets are of a fine 
chestnut-brown colour. Exhibited by Messrs. Kelway 
& Son, Langport, Somerset. 
Yiola, Lucy Ashton. 
The ground colour of this pretty new bedding variety 
is white, with several violet lines radiating from the 
small yellow eye on the three lower petals, and the 
margins, broadest on the two upper petals, are purple, 
somewhat shaded with mauve. It was also certi¬ 
ficated at Glasgow in July last. Exhibited by Messrs. 
Dobbie & Co., Rothesay, N.B. 
Hollyhocks. 
Scarlet Gem. —The blooms of this seedling are of 
great size, fully double, semi-globular, and of an 
intense reddish crimson. The central petals are 
undulated, while the outside ones are larger and flat, 
forming a sort of decorative background, which shows 
off the rest of the flower to advantage. 
■William Archer. —-The flowers in this case were 
similar in structure to the last, but the primary or 
guard petals are nearly hidden by the central 
mass. They are, however, very different in colour, 
being of a deep maroon-red, and, from a florist’s point 
of view, equally as good. Exhibited by Messrs. 
Webb & Brand, The Nurseries, Saffron Waldon. 
By the Fruit Committee. 
Apple, Beauty of Bath. 
The fruits of this seedling prove it to be an early 
Apple, of small size and great beauty. It is somewhat 
flattened at each end, perfectly even on the surface, 
with the stalk set in an even cup-shaped depression, 
and having a small closed eye. With the exception of 
the shaded side, which is green, the rest is of a lively 
crimson-red, conspicuously spotted with green. The 
flesh is firm and pale yellow. Exhibited by Messrs. 
G. Cooling & Sons, Bath. 
Cherry, Emperor Francis. 
This is a large red Cherry, shortly and bluntly 
conical in outline, with a shallow depression at the 
base and apex, and a faint indication of furrow on one 
side. It is a deep red, becoming crimson ultimately, 
faintly streaked with a paler colour, and of fine flavour 
when perfectly mature. Exhibited by Messrs. T. 
Rivers & Son, Sawbridgeworth, Herts. 
Pear, Madamoiselle de Solange. 
The fruit of this variety is very small, but very 
early and distinct. It is shortly Pear-shaped, with a 
small shallow open eye, and the stalk, which is moder¬ 
ately strong and about f in. in length, is set on 
obliquely in a very shallow depression. The s kin is 
even, deep green and marked with a few russety spots, 
especially on one side. Exhibited by Messrs. J. Yeitch 
& Sons, Chelsea. 
A HEAVY CROP OF CUCUMBERS. 
At the trial grounds of Messrs. J. Yeitch & Sons at 
Chiswick, a fine crop of the Telegraph Cucumber may 
now be seen fast approaching maturity, as they are 
grown solely for seed. The plants are grown in a 
small span-roofed house or pit solely devoted to their 
culture. The structure, measured from the outside, is 
only 40 ft. in length, in two divisions, each accommo¬ 
dating ten plants, which are trained within a short 
distance of the glass on strong diagonal meshed wire 
netting. As a sunk pathway goes down the middle 
between the two beds, it follows that there is no 
available space for the Cucumbers, except the area of 
glass, which is of no great extent, as the pit is low and 
narrow. 
No other support is required than the tying of the 
stems firmly to the wires, and the Cucumbers hang 
suspended into the body of the house, showing them¬ 
selves in the most conspicuous manner to the eye of the 
beholder, as the leaves are all above the wires, thus 
excluding direct sunshine from the fruit. The twenty 
plants bear, in the aggregate, from 480 to 500 good 
fruits, making an average of twenty-five to each ; and 
although the crop is tolerably even, some of the plants 
carry a much greater number than this. The fruits 
are generally quite straight, with a smooth or even 
surface, and measure from 20 ins. to 25 ins. in length, 
with girth in proportion, the average length being 
22 ins. The house was planted in May, and com¬ 
menced fruiting on June 2nd. Most of the fruits still 
hang on the plants, though the greater part are now 
turning yellow and fast reaching maturity. Besides 
the tying, training, and all other cultural matters, 
some idea of the attention they require may be gleaned 
from the fact that every flower which is to develop 
into seed-bearing fruit has to be carefully fertilised 
with pollen from other flowers.

THE MILDEW OF ROSES. 
There are two forms of this—namely, rust and 
brand, both identical but different stages in the life 
cycle of Phragmidium mucronatum, or P. subcorticium 
of another author. Amongst gardeners, however, 
mildew is simply mildew, and they have been accused 
of only recognising two kinds of fungi—namely, mildew 
and Mushrooms. A little acquaintance with the 
microscope would soon dispel this illusion, and show 
that Rose mildew is differently constructed according 
to the progress of its development. The two stages 
above mentioned are, moreover, so different in general 
appearance that they were formerly regarded as distinct 
species. 
When the spores germinate, they develop a whitish 
but extremely fine thready material, that ramifies in 
the tissue of the leaf, destroying and appropriating its 
substance, causing the Rose-leaves to become crumpled 
and otherwise deformed, and greatly affecting their 
health, as is well known. Later on, reddish or rust- 
coloured spots appear, due to the formation of single- 
celled spores. This is the so-called rust—the Uredo 
rosse of old authors. These are easily blown about by 
the wind, and propagate the disease with alarming 
rapidity if not checked. This continues for some time 
during the early stages of the parasite ; but later on 
black spots appear, known as brand (the Puccinia 
rosse of the old school), which is merely the ultimate 
stage in the life history of Phragmidium mucronatum. 
These can be detected with an ordinary lens as clusters 
of stalked spores of a black colour, and are the resting 
or hibernating spores of the fungus. With the aid of 
a microscope they are seen to consist of a short string 
of cells, dark-coloured, and thick-walled, seated on a 
colourless stalk. Each of these cells constitutes a 
resting spore that lies dormant during winter, and 
renews the life of the parasite and its work of des¬ 
truction next year. 
If attacked in the early stages by a dusting of 
flowers of sulphur the disease is arrested, and a cure 
effected ; but after it has reached the brand stage, the 
same application is found to be ineffectual. The 
explanation is that sulphur is powerless to kill the 
thick-walled spores, and the only remedy lies in 
picking the leaves if the affected ones are not so 
numerous as to make this impracticable ; otherwise 
collecting them after they fall in autumn, and burning 
or burying them deeply, preferably the former, is the 
only course left open for the Rose grower to pursue. —
