the colour present. (First-class Certificate.) De B. 
Crawshay, Esq. (gardener, Mr. S. Cooke), Rosefield, 
Sevenoaks. 
Odontoglossum crispum purpurascens, Nov 
var. —Here we have another fine, imbricated flower, 
suffused with rose and spotted with rose and brown. 
Good cultivation is shown by the fact that the plant 
carries four successive years’ leaves. (Award of 
Merit.) Sir Trevor Lawrence, Bart, (grower, Mr. 
W. H. White), Burford Lodge, Dorking. 
Cattleya Mossiae Lawrenceae, Nov. var.— The 
sepals and petals are pure white. The tube of the lip 
is yellow at the base, the. colour being caused by the 
orange blotch which extends to the base; the 
lamina on the other hand is netted with pale lilac, 
making a delicately chaste and pale variety. (Award 
of Merit.) Sir Trevor Lawrence, Bart. 
Odontoglossum harryano-crispum, Nov. hyb. 
nat. —This is presumed to be a natural hybrid 
between the two species indicated by the name. 
The spreading sepals are heavily blotched with 
brown, and overlaid with lilac at the tip. The 
spreading, lanceolate petals are broader, and have a 
very large, curiously lobed brown blotch surround¬ 
ing a white, basal area, on which is a violet blotch. 
The flat lip is very broad, triangular, white in the 
upper third of its length, but downwards the whole 
area is covered with short, horizontal, violet stripes. 
The yellow crest consists of finger-like, radiating 
plates. It is a strange looking but very pretty 
hybrid; and the plant had two scapes, with three 
flowers each. (First-class Certificate.) Sir F. Wigan, 
Bart, (grower Mr. W. H. Young), Clare Lawn, East 
Sheen. 
Eria acervata. —The short, stout, leafy stems o* 
this species, carry arching racemes of small white 
flowers, having greenish pedicels. (Botanical Certi¬ 
ficate.) Sir F. Wigan, Bart. 
Laeliocattleya dominiana Fire King, Nov. 
var. —The original, bigeneric hybrid was obtained by 
the crossing of Laelia purpurata with Cattleya 
dowiana. The sepals and petals of the new variety 
are bright purple-rose. The lamina of the large 
and showy lip is of a rich crimson-purple; the 
throat has the usual orange blotch, and the tube 
has crimson lines, as seen in C. dowiana. (First- 
class Certificate.) Mrs. Briggs-Bury (gardener, Mr. 
Wilkinson), Bank House, Accrington. 
Laelia tenebrosa Victor Warburton, Nov. 
var. —The sepals and petals of this light variety are 
pale yellow tinted with bronze. The lip is nearly 
white and variegated or tinted with rose on the 
lamina. (Award of Merit.) A. Warburton, Esq. 
(gardener, Mr. Lofthouse), Vine House, Haslingden. 
Gongora gratulabunda. —The flowers of this 
curious little Orchid are pale, nearly white, and 
freely spotted with purple. (Botanical Certificate.) 
F. W. Moore, Esq., Glasnevin, Dublin. 
Flora! Committee. 
Davallia illustris. —The arching fronds of this 
Haresfoot Fern are about a yard in length, and have 
a triangular lamina that is four to five times pinnati- 
sect. Each pinna is drawn out into a slender tail; and 
the ultimate segments are wedge-shaped. It is a 
graceful and handsome species. (First-class Certi¬ 
ficate.) Messrs. J. Veitch & Sons, Ltd. 
Dracaena indivisa Schneideri. —The linear, 
leathery leaves of this beautiful variety have a 
slender red midrib and the whole of the base red, 
otherwise they are like the type. (First-class 
Certificate.) Messrs. J. Veitch & Sons, Ltd. 
Carnation Trojan (Martin R. Smith.).—Here we 
have a border variety of first-class form, great refine¬ 
ment, and pure white, broad, rounded, smooth petals. 
(Award of Merit.) Mr. James Douglas, Edenside, 
Great Bookham, Surrey. 
Delphinium Sir Walter Scott. —The outer 
sepals of this handsome, semi-double variety are of 
an intense, almost Gentian blue. The inner ones, 
on the contrary, are violet-purple. The small central 
petals are black. (Award of Merit.) Messrs. Kelway 
& Son, Langport, Somerset. 
Carnation Lady Gerard. —This bold and hand¬ 
some Malmaison Carnation was much admired by 
visitors, particularly the ladies. The flowers are of 
great size, and may be described as creamy-white, 
fading to cream or showing streaks of yellow when 
old. (Award of Merit.) Mr. H. Walters, Eastwell 
Gardens, Ashford, Kent. 
Pelargonium Fire Dragon. —The new Cactus- 
flowered Pelargonium has at last been recognised 
with an Award of Merit. It may lead up to some¬ 
thing finer and even more singular. It originated 
as a seedling from Raspail Improved. The long, 
narrow petals are revolute at the sides, which recalls 
the behaviour of the Cactus Dahlias. Mr. E. S. 
Fowell, Llewot, Hampton Hill.

Kitctien Barden Calendar. 
Many of both the early and second early varieties of 
Potatos will now be lifted, so that room will be found 
for planting the late winter crops. In many places 
too the ground has been thoroughly moistened by the 
recent heavy rains, so that plants put out now will 
soon take hold. In gardens that have to be cropped 
heavily there is usually much difficulty in getting 
many of such things planted at the proper time, in 
which case there is always more trouble and risk 
attending the planting. Early Peas as a rule have 
not been up to the standard this year, the crops 
being light. As such things are cleared off the ground 
ought to be occupied with something else. 
It is advisable to make a sowing of Carrots now 
for winter use. In fact seed sown at the present 
time would under good cultivation produce very 
serviceable roots by October, and seed sown on a 
warm border about the third week in the month 
would give nice sweet roots during winter and 
spring. The varieties we grow are Parisian Forcing, 
Carter’s Golden Ball, Gem and Inimitable Forcing. 
About the third week in this month is a good time 
for sowing Turnips; but where the soil is good those 
sown the second week in August will be far better for 
winter and spring use. When the autumn has been 
mild the roots have continued growing through 
November so that seed sown at the latter end of 
August has produced fine roots. There is always 
more satisfaction in having small, crisp, sweet roots 
than those of larger size if they have become tough 
and stringy. 
The last sowing of Peas should now be made in 
the open, any sown after the middle of the month 
ought to be on a border where protection could be 
afforded in the autumn in case of early frost. We 
sometimes have a mild season when good Peas are 
gathered in November ; but as our climate is so 
variable it is always well to be on the safe side, as 
a little frost injures the tender varieties when in 
bloom. The rows should be sown about eighteen 
inches apart so that a framework can be put over 
them for protection. After using the best marrow 
varieties one does not like to go back to those hard 
round-seeded kinds, but as there there are so many 
first-class dwarf varieties of the former there is no 
necessity for sowing these latter. William Hurst, 
Carter’s Forcing, Excelsior and the like are all good, 
growing about eighteen inches high, therefore suit¬ 
able for sowing on a warm border or in frames. 
The late Celery should be got into the trenches 
at the first favourable opportunity, even if the plants 
are small, as it is far better to plant them out than 
allow them to stand longer close together. In some 
places the Celery Fly is troublesome this season. 
Where this is so, syringe the plants with a solution 
of permanganate of potash. This will do the 
plants no harm, but will keep off the fly. Lettuce 
and such like plants suffer much during hot dry 
weather and soon go to seed. Where the ground is 
at all dry a liberal soaking of manure water should 
be given, for unless the plants are kept growing they 
will be of little value. Runner Beans may still be 
sown with every prospect of success .—Kitchen

The undermentioned subjects were brought before 
the members of the Scientific Committee of the 
Royal Horticultural Society on the 13th ult. 
Panax mastersianus.—Dr. Masters exhibited 
a flowering spray of this plant, which probably 
came from New Guinea. It has never been thoroughly 
described hitherto, as no flowers had been seen. 
Dr. Masters undertook to examine them, which 
appeared to be all male, and report upon it. 
Cattleya Mossiae. — He also exhibited a 
blossom of this Orchid strangely malformed, which 
he also undertook to examine. 
Lilac with central (terminal) bud aborted. 
—He brought sprays to show the presence of this 
bud lying between two opposite fully formed buds. 
It is said to be always aborted by frost; but as it is 
invariably the case, it would be more likely to be 
atrophied, in consequence of all the nourishment 
being conveyed into the two opposite buds. 
Hemerocallis leaf diseased.— Dr. Smith 
reports as follows upon leaves sent to the last meet¬ 
ing :—"The reddish spots on leaf sent are caused by a 
fungus. Each spot is £to J-inch diameter, and con¬ 
sists of a patch of cavities (pycnidia) sunk in the leaf 
tissue. From these tiny conida are given off to dis¬ 
perse the fungus. In addition to the internal 
pycnidia, another form of pycnidium is formed on 
the surface, when a portion of the leaf with spots is 
kept in a moist chamber ; these latter also give off 
tiny conidia. The forms of pycnidium and their 
structure refer the fungus to the genus Asteroma. 
Farlow, in his • Host Index for U.S. America,’ gives 
a form Asteroma Lineola, the pycnidial stage of 
Dothidea Lineola. The ascospore or Dothidea stage 
is not present, as far as I can see, on leaf sent." 
Diseased Peach.—The following is also Dr. W. 
G. Smith’s report;—“ The fruit sent showed a large 
patch of fungus mycelium with conidia. Two forms 
of conidia occurred, by which the rot might be referred 
either to black spot disease (Cladosporium carpo- 
philum) or the fruit rot (Monilia fructigena). In 
transit the fungus spot appears to have enlarged 
enormously, and it looked quite unlike what one 
generally sees in either of the above Peach diseases. 
In any case it is a distinct fruit rot, and controllable 
by spraying methods, 
Peridermium Plowrighti(Kleb).—The following 
communication was received from Dr. Plowright, 
with illustrative specimens:—-'' The specimens of 
Peridermium sent herewith were produced by arti¬ 
ficial culture, and afford an illustration of how easy 
a matter it is to unravel a mystery when one once 
has the clue to it. It is just twenty-five years ago 
since Wolff showed that Coleosporium Senecionis 
was connected with Peridermium Pini on Pinus 
sylvestris. This Peridermium is frequent upon the 
Fir trees near King’s Lynn, so that I had ample 
opportunity of confirming Wolff's observations. 
As a matter of fact, between the years 1881 and 
1888, on ten separate and distinct occasions, I did 
apply the spores of Peridermium Pini to Senecio 
vulgaris. Once, and once only, did I succeed in pro¬ 
ducing the uredo on the last named plaDt. My 
non-success I attributed to some error in manipula¬ 
tion, and as I was engaged with other species I did 
not follow the research up. Dr Klebahn, of 
Hamburg, however, set about the problem, and 
soon cleared the matter up. He showed that the 
Coleosporia as a genus had their aecidiospores on 
Pinus sylvestris, and not C. Senecionis alone. The 
species on Tussilago Farfara, which is exceedingly 
common all over England, was one of the forms to 
which Dr. Klebahn directed his attention, and he 
gave the above name to its aecidiospores. The 
specimens sent herewith were produced by artificial 
culture. On October i6tb, 1898, a leaf of Coltsfoot, 
with the telutospores of Coleosporium Tussilagiois 
abundantly upon it, was fastened upon young Pinus 
sylvestris ; on Febuary 20th suspicious spots began 
to show, but it was (not) until April 22nd that an 
abundant development of the Peridermium was ob¬ 
served. On that date the Coltsfoot leaf was still at¬ 
tached to the Fir, and the most abundant develop¬ 
ment of Peridermium was seen to be immediately 
beneath it. As this experiment was performed some 
three miles from my house the plants were not visited 
so often as they otherwise would have been. On April 
25th two young plants of Tussilago Farfara were in¬ 
fected with the above aecidiospores, and on May 13th 
each was found to be abundantly affected with the 
uredo of Coleosporium Tussilaginis; they were 
gathered, and are also sent herewith. I have to 
thank Mr. Walter Scott, of the Golden Ball Nurseries, 
for the material employed in these cultures, and Mr. 
Rodgers for his assistance in looking after the plants."
